-4.15 Fri Mar 1 12:04:50 CET 2013
- - destroying a non-default loop would stop the global waitpid
- watcher (Denis Bilenko).
- - queueing pending watchers of higher priority from a watcher now invokes
- them in a timely fashion (reported by Denis Bilenko).
- - add throw() to all libev functions that cannot throw exceptions, for
- further code size decrease when compiling for C++.
- - add throw () to callbacks that must not throw exceptions (allocator,
- syserr, loop acquire/release, periodic reschedule cbs).
- - fix event_base_loop return code, add event_get_callback, event_base_new,
- event_base_get_method calls to improve libevent 1.x emulation and add
- some libevent 2.x functionality (based on a patch by Jeff Davey).
- - add more memory fences to fix a bug reported by Jeff Davey. Better
- be overfenced than underprotected.
- - ev_run now returns a boolean status (true meaning watchers are
- still active).
- - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
- libev's EV_ERROR (reported by 191919).
- - (ecb) add memory fence support for xlC (Darin McBride).
- - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
- - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
- - work around some kernels losing file descriptors by leaking
- the kqueue descriptor in the child.
- - work around linux inotify not reporting IN_ATTRIB changes for directories
- in many cases.
- - include sys/syscall.h instead of plain syscall.h.
- - check for io watcher loops in ev_verify, check for the most
- common reported usage bug in ev_io_start.
- - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
- - always use WSASend/WSARecv directly on windows, hoping that this
- works in all cases (unlike read/write/send/recv...).
- - try to detect signals around a fork faster (test program by
- Denis Bilenko).
- - work around recent glibc versions that leak memory in realloc.
- - rename ev::embed::set to ev::embed::set_embed to avoid clashing
- the watcher base set (loop) method.
- - rewrite the async/signal pipe logic to always keep a valid fd, which
- simplifies (and hopefuly correctifies :) the race checking
- on fork, at the cost of one extra fd.
- - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
- inotify-supporting filesystems.
- - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
- versions ignore it before
- (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
- - add some untested android support.
- - enum expressions must be of type int (reported by Juan Pablo L).
-
-4.11 Sat Feb 4 19:52:39 CET 2012
- - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
- was documented already, but not implemented in the repeating case.
- - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
- - fix a race where the workaround against the epoll fork bugs
- caused signals to not be handled anymore.
- - correct backend_fudge for most backends, and implement a windows
- specific workaround to avoid looping because we call both
- select and Sleep, both with different time resolutions.
- - document range and guarantees of ev_sleep.
- - document reasonable ranges for periodics interval and offset.
- - rename backend_fudge to backend_mintime to avoid future confusion :)
- - change the default periodic reschedule function to hopefully be more
- exact and correct even in corner cases or in the far future.
- - do not rely on -lm anymore: use it when available but use our
- own floor () if it is missing. This should make it easier to embed,
- as no external libraries are required.
- - strategically import macros from libecb and mark rarely-used functions
- as cache-cold (saving almost 2k code size on typical amd64 setups).
- - add Symbols.ev and Symbols.event files, that were missing.
- - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
- - fix #3 "be smart about timeouts" to not "deadlock" when
- timeout == now, also improve the section overall.
- - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
- - support new EV_API_STATIC mode to make all libev symbols
- static.
- - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
- were empty.
-
-4.04 Wed Feb 16 09:01:51 CET 2011
- - fix two problems in the native win32 backend, where reuse of fd's
- with different underlying handles caused handles not to be removed
- or added to the select set (analyzed and tested by Bert Belder).
- - do no rely on ceil() in ev_e?poll.c.
- - backport libev to HP-UX versions before 11 v3.
- - configure did not detect nanosleep and clock_gettime properly when
- they are available in the libc (as opposed to -lrt).
-
-4.03 Tue Jan 11 14:37:25 CET 2011
- - officially support polling files with all backends.
- - support files, /dev/zero etc. the same way as select in the epoll
- backend, by generating events on our own.
- - ports backend: work around solaris bug 6874410 and many related ones
- (EINTR, maybe more), with no performance loss (note that the solaris
- bug report is actually wrong, reality is far more bizarre and broken
- than that).
- - define EV_READ/EV_WRITE as macros in event.h, as some programs use
- #ifdef to test for them.
- - new (experimental) function: ev_feed_signal.
- - new (to become default) EVFLAG_NOSIGMASK flag.
- - new EVBACKEND_MASK symbol.
- - updated COMMON IDIOMS SECTION.
-
-4.01 Fri Nov 5 21:51:29 CET 2010
- - automake fucked it up, apparently, --add-missing -f is not quite enough
- to make it update its files, so 4.00 didn't install ev++.h and
- event.h on make install. grrr.
- - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
- - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
- - use "(libev) " prefix for all libev error messages now.
-
-4.00 Mon Oct 25 12:32:12 CEST 2010
- - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
- - ev_embed_stop did not correctly stop the watcher (very good
- testcase by Vladimir Timofeev).
- - ev_run will now always update the current loop time - it erroneously
- didn't when idle watchers were active, causing timers not to fire.
- - fix a bug where a timeout of zero caused the timer not to fire
- in the libevent emulation (testcase by Péter Szabó).
- - applied win32 fixes by Michael Lenaghan (also James Mansion).
- - replace EV_MINIMAL by EV_FEATURES.
- - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
- seems the former is *much* faster than the latter.
- - linux kernel version detection (for inotify bug workarounds)
- did not work properly.
- - reduce the number of spurious wake-ups with the ports backend.
- - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
- - do async init within ev_async_start, not ev_async_set, which avoids
- an API quirk where the set function must be called in the C++ API
- even when there is nothing to set.
- - add (undocumented) EV_ENABLE when adding events with kqueue,
- this might help with OS X, which seems to need it despite documenting
- not to need it (helpfully pointed out by Tilghman Lesher).
- - do not use poll by default on freebsd, it's broken (what isn't
- on freebsd...).
- - allow to embed epoll on kernels >= 2.6.32.
- - configure now prepends -O3, not appends it, so one can still
- override it.
- - ev.pod: greatly expanded the portability section, added a porting
- section, a description of watcher states and made lots of minor fixes.
- - disable poll backend on AIX, the poll header spams the namespace
- and it's not worth working around dead platforms (reported
- and analyzed by Aivars Kalvans).
- - improve header file compatibility of the standalone eventfd code
- in an obscure case.
- - implement EV_AVOID_STDIO option.
- - do not use sscanf to parse linux version number (smaller, faster,
- no sscanf dependency).
- - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
- - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
- - add section on accept() problems to the manpage.
- - rename EV_TIMEOUT to EV_TIMER.
- - rename ev_loop_count/depth/verify/loop/unloop.
- - remove ev_default_destroy and ev_default_fork.
- - switch to two-digit minor version.
- - work around an apparent gentoo compiler bug.
- - define _DARWIN_UNLIMITED_SELECT. just so.
- - use enum instead of #define for most constants.
- - improve compatibility to older C++ compilers.
- - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
- default arguments when compiled as C++.
- - enable automake dependency tracking.
- - ev_loop_new no longer leaks memory when loop creation failed.
- - new ev_cleanup watcher type.
-
-3.9 Thu Dec 31 07:59:59 CET 2009
- - signalfd is no longer used by default and has to be requested
- explicitly - this means that easy to catch bugs become hard to
- catch race conditions, but the users have spoken.
- - point out the unspecified signal mask in the documentation, and
- that this is a race condition regardless of EV_SIGNALFD.
- - backport inotify code to C89.
- - inotify file descriptors could leak into child processes.
- - ev_stat watchers could keep an erroneous extra ref on the loop,
- preventing exit when unregistering all watchers (testcases
- provided by ry@tinyclouds.org).
- - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
- symbols to make it easier for apps to do their own fd management.
- - support EV_IDLE_ENABLE being disabled in ev++.h
- (patch by Didier Spezia).
- - take advantage of inotify_init1, if available, to set cloexec/nonblock
- on fd creation, to avoid races.
- - the signal handling pipe wasn't always initialised under windows
- (analysed by lekma).
- - changed minimum glibc requirement from glibc 2.9 to 2.7, for
- signalfd.
- - add missing string.h include (Denis F. Latypoff).
- - only replace ev_stat.prev when we detect an actual difference,
- so prev is (almost) always different to attr. this might
- have caused the problems with 04_stat.t.
- - add ev::timer->remaining () method to C++ API.
-
-3.8 Sun Aug 9 14:30:45 CEST 2009
- - incompatible change: do not necessarily reset signal handler
- to SIG_DFL when a sighandler is stopped.
- - ev_default_destroy did not properly free or zero some members,
- potentially causing crashes and memory corruption on repeated
- ev_default_destroy/ev_default_loop calls.
- - take advantage of signalfd on GNU/Linux systems.
- - document that the signal mask might be in an unspecified
- state when using libev's signal handling.
- - take advantage of some GNU/Linux calls to set cloexec/nonblock
- on fd creation, to avoid race conditions.
-
-3.7 Fri Jul 17 16:36:32 CEST 2009
- - ev_unloop and ev_loop wrongly used a global variable to exit loops,
- instead of using a per-loop variable (bug caught by accident...).
- - the ev_set_io_collect_interval interpretation has changed.
- - add new functionality: ev_set_userdata, ev_userdata,
- ev_set_invoke_pending_cb, ev_set_loop_release_cb,
- ev_invoke_pending, ev_pending_count, together with a long example
- about thread locking.
- - add ev_timer_remaining (as requested by Denis F. Latypoff).
- - add ev_loop_depth.
- - calling ev_unloop in fork/prepare watchers will no longer poll
- for new events.
- - Denis F. Latypoff corrected many typos in example code snippets.
- - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
- check that the syscall number is available before trying to
- use it (reported by ry@tinyclouds).
- - use GetSystemTimeAsFileTime instead of _timeb on windows, for
- slightly higher accuracy.
- - properly declare ev_loop_verify and ev_now_update even when
- !EV_MULTIPLICITY.
- - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
- - support EV_MINIMAL==2 for a reduced API.
- - actually 0-initialise struct sigaction when installing signals.
- - add section on hibernate and stopped processes to ev_timer docs.
-
-3.6 Tue Apr 28 02:49:30 CEST 2009
- - multiple timers becoming ready within an event loop iteration
- will be invoked in the "correct" order now.
- - do not leave the event loop early just because we have no active
- watchers, fixing a problem when embedding a kqueue loop
- that has active kernel events but no registered watchers
- (reported by blacksand blacksand).
- - correctly zero the idx values for arrays, so destroying and
- reinitialising the default loop actually works (patch by
- Malek Hadj-Ali).
- - implement ev_suspend and ev_resume.
- - new EV_CUSTOM revents flag for use by applications.
- - add documentation section about priorities.
- - add a glossary to the dcoumentation.
- - extend the ev_fork description slightly.
- - optimize a jump out of call_pending.
-
-3.53 Sun Feb 15 02:38:20 CET 2009
- - fix a bug in event pipe creation on win32 that would cause a
- failed assertion on event loop creation (patch by Malek Hadj-Ali).
- - probe for CLOCK_REALTIME support at runtime as well and fall
- back to gettimeofday if there is an error, to support older
- operating systems with newer header files/libraries.
- - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
- (default most everywhere), otherwise not.
-
-3.52 Wed Jan 7 21:43:02 CET 2009
- - fix compilation of select backend in fd_set mode when NFDBITS is
- missing (to get it to compile on QNX, reported by Rodrigo Campos).
- - better select-nfds handling when select backend is in fd_set mode.
- - diagnose fd_set overruns when select backend is in fd_set mode.
- - due to a thinko, instead of disabling everything but
- select on the borked OS X platform, everything but select was
- allowed (reported by Emanuele Giaquinta).
- - actually verify that local and remote port are matching in
- libev's socketpair emulation, which makes denial-of-service
- attacks harder (but not impossible - it's windows). Make sure
- it even works under vista, which thinks that getpeer/sockname
- should return fantasy port numbers.
- - include "libev" in all assertion messages for potentially
- clearer diagnostics.
- - event_get_version (libevent compatibility) returned
- a useless string instead of the expected version string
- (patch by W.C.A. Wijngaards).
-
-3.51 Wed Dec 24 23:00:11 CET 2008
- - fix a bug where an inotify watcher was added twice, causing
- freezes on hash collisions (reported and analysed by Graham Leggett).
- - new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
- a direct syscall - slower, but no dependency on librt et al.
- - assume negative return values != -1 signals success of port_getn
- (http://cvs.epicsol.org/cgi/viewcvs.cgi/epic5/source/newio.c?rev=1.52)
- (no known failure reports, but it doesn't hurt).
- - fork detection in ev_embed now stops and restarts the watcher
- automatically.
- - EXPERIMENTAL: default the method to operator () in ev++.h,
- to make it nicer to use functors (requested by Benedek László).
- - fixed const object callbacks in ev++.h.
- - replaced loop_ref argument of watcher.set (loop) by a direct
- ev_loop * in ev++.h, to avoid clashes with functor patch.
- - do not try to watch the empty string via inotify.
- - inotify watchers could be leaked under certain circumstances.
- - OS X 10.5 is actually even more broken than earlier versions,
- so fall back to select on that piece of garbage.
- - fixed some weirdness in the ev_embed documentation.
-
-3.49 Wed Nov 19 11:26:53 CET 2008
- - ev_stat watchers will now use inotify as a mere hint on
- kernels <2.6.25, or if the filesystem is not in the
- "known to be good" list.
- - better mingw32 compatibility (it's not as borked as native win32)
- (analysed by Roger Pack).
- - include stdio.h in the example program, as too many people are
- confused by the weird C language otherwise. I guess the next thing
- I get told is that the "..." ellipses in the examples don't compile
- with their C compiler.
-
-3.48 Thu Oct 30 09:02:37 CET 2008
- - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll
- backend by assuming the kernel event mask hasn't changed if
- ADD fails with EEXIST.
- - work around spurious event notification bugs in epoll by using
- a 32-bit generation counter. recreate kernel state if we receive
- spurious notifications or unwanted events. this is very costly,
- but I didn't come up with this horrible design.
- - use memset to initialise most arrays now and do away with the
- init functions.
- - expand time-out strategies into a "Be smart about timeouts" section.
- - drop the "struct" from all ev_watcher declarations in the
- documentation and did other clarifications (yeah, it was a mistake
- to have a struct AND a function called ev_loop).
- - fix a bug where ev_default would not initialise the default
- loop again after it was destroyed with ev_default_destroy.
- - rename syserr to ev_syserr to avoid name clashes when embedding,
- do similar changes for event.c.
-
-3.45 Tue Oct 21 21:59:26 CEST 2008
- - disable inotify usage on linux <2.6.25, as it is broken
- (reported by Yoann Vandoorselaere).
- - ev_stat erroneously would try to add inotify watchers
- even when inotify wasn't available (this should only
- have a performance impact).
- - ev_once now passes both timeout and io to the callback if both
- occur concurrently, instead of giving timeouts precedence.
- - disable EV_USE_INOTIFY when sys/inotify.h is too old.
-
-3.44 Mon Sep 29 05:18:39 CEST 2008
- - embed watchers now automatically invoke ev_loop_fork on the
- embedded loop when the parent loop forks.
- - new function: ev_now_update (loop).
- - verify_watcher was not marked static.
- - improve the "associating..." manpage section.
- - documentation tweaks here and there.
-
-3.43 Sun Jul 6 05:34:41 CEST 2008
- - include more include files on windows to get struct _stati64
- (reported by Chris Hulbert, but doesn't quite fix his issue).
- - add missing #include <io.h> in ev.c on windows (reported by
- Matt Tolton).
-
-3.42 Tue Jun 17 12:12:07 CEST 2008
- - work around yet another windows bug: FD_SET actually adds fd's
- multiple times to the fd_*SET*, despite official MSN docs claiming
- otherwise. Reported and well-analysed by Matt Tolton.
- - define NFDBITS to 0 when EV_SELECT_IS_WINSOCKET to make it compile
- (reported any analysed by Chris Hulbert).
- - fix a bug in ev_ebadf (this function is only used to catch
- programming errors in the libev user). reported by Matt Tolton.
- - fix a bug in fd_intern on win32 (could lead to compile errors
- under some circumstances, but would work correctly if it compiles).
- reported by Matt Tolton.
- - (try to) work around missing lstat on windows.
- - pass in the write fd set as except fd set under windows. windows
- is so uncontrollably lame that it requires this. this means that
- switching off oobinline is not supported (but tcp/ip doesn't
- have oob, so that would be stupid anyways.
- - use posix module symbol to auto-detect monotonic clock presence
- and some other default values.

-3.41 Fri May 23 18:42:54 CEST 2008
- - work around an obscure bug in winsocket select: if you
- provide only empty fd sets then select returns WSAEINVAL. how sucky.
- - improve timer scheduling stability and reduce use of time_epsilon.
- - use 1-based 2-heap for EV_MINIMAL, simplifies code, reduces
- codesize and makes for better cache-efficiency.
- - use 3-based 4-heap for !EV_MINIMAL. this makes better use
- of cpu cache lines and gives better growth behaviour than
- 2-based heaps.
- - cache timestamp within heap for !EV_MINIMAL, to avoid random
- memory accesses.
- - document/add EV_USE_4HEAP and EV_HEAP_CACHE_AT.
- - fix a potential aliasing issue in ev_timer_again.
- - add/document ev_periodic_at, retract direct access to ->at.
- - improve ev_stat docs.
- - add portability requirements section.
- - fix manpage headers etc.
- - normalise WSA error codes to lower range on windows.
- - add consistency check code that can be called automatically
- or on demand to check for internal structures (ev_loop_verify).
-
-3.31 Wed Apr 16 20:45:04 CEST 2008
- - added last minute fix for ev_poll.c by Brandon Black.
-
-3.3 Wed Apr 16 19:04:10 CEST 2008
- - event_base_loopexit should return 0 on success
- (W.C.A. Wijngaards).
- - added linux eventfd support.
- - try to autodetect epoll and inotify support
- by libc header version if not using autoconf.
- - new symbols: EV_DEFAULT_UC and EV_DEFAULT_UC_.
- - declare functions defined in ev.h as inline if
- C99 or gcc are available.
- - enable inlining with gcc versions 2 and 3.
- - work around broken poll implementations potentially
- not clearing revents field in ev_poll (Brandon Black)
- (no such systems are known at this time).
- - work around a bug in realloc on openbsd and darwin,
- also makes the erroneous valgrind complaints
- go away (noted by various people).
- - fix ev_async_pending, add c++ wrapper for ev_async
- (based on patch sent by Johannes Deisenhofer).
- - add sensible set method to ev::embed.
- - made integer constants type int in ev.h.
-
-3.2 Wed Apr 2 17:11:19 CEST 2008
- - fix a 64 bit overflow issue in the select backend,
- by using fd_mask instead of int for the mask.
- - rename internal sighandler to avoid clash with very old perls.
- - entering ev_loop will not clear the ONESHOT or NONBLOCKING
- flags of any outer loops anymore.
- - add ev_async_pending.
-
-3.1 Thu Mar 13 13:45:22 CET 2008
- - implement ev_async watchers.
- - only initialise signal pipe on demand.
- - make use of sig_atomic_t configurable.
- - improved documentation.
-
-3.0 Mon Jan 28 13:14:47 CET 2008
- - API/ABI bump to version 3.0.
- - ev++.h includes "ev.h" by default now, not <ev.h>.
- - slightly improved documentation.
- - speed up signal detection after a fork.
- - only optionally return trace status changed in ev_child
- watchers.
- - experimental (and undocumented) loop wrappers for ev++.h.
-
-2.01 Tue Dec 25 08:04:41 CET 2007
- - separate Changes file.
- - fix ev_path_set => ev_stat_set typo.
- - remove event_compat.h from the libev tarball.
- - change how include files are found.
- - doc updates.
- - update licenses, explicitly allow for GPL relicensing.
-
-2.0 Sat Dec 22 17:47:03 CET 2007
- - new ev_sleep, ev_set_(io|timeout)_collect_interval.
- - removed epoll from embeddable fd set.
- - fix embed watchers.
- - renamed ev_embed.loop to other.
- - added exported Symbol tables.
- - undefine member wrapper macros at the end of ev.c.
- - respect EV_H in ev++.h.
-
-1.86 Tue Dec 18 02:36:57 CET 2007
- - fix memleak on loop destroy (not relevant for perl).
-
-1.85 Fri Dec 14 20:32:40 CET 2007
- - fix some aliasing issues w.r.t. timers and periodics
- (not relevant for perl).
-
-(for historic versions refer to EV/Changes, found in the Perl interface)
-
-0.1 Wed Oct 31 21:31:48 CET 2007
- - original version; hacked together in <24h.

-libev is a high-performance event loop/event model with lots of features.
-(see benchmark at http://libev.schmorp.de/bench.html)
-
-
-ABOUT
-
- Homepage: http://software.schmorp.de/pkg/libev
- Mailinglist: libev@lists.schmorp.de
- http://lists.schmorp.de/cgi-bin/mailman/listinfo/libev
- Library Documentation: http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod
-
- Libev is modelled (very losely) after libevent and the Event perl
- module, but is faster, scales better and is more correct, and also more
- featureful. And also smaller. Yay.
-
- Some of the specialties of libev not commonly found elsewhere are:
-
- - extensive and detailed, readable documentation (not doxygen garbage).
- - fully supports fork, can detect fork in various ways and automatically
- re-arms kernel mechanisms that do not support fork.
- - highly optimised select, poll, epoll, kqueue and event ports backends.
- - filesystem object (path) watching (with optional linux inotify support).
- - wallclock-based times (using absolute time, cron-like).
- - relative timers/timeouts (handle time jumps).
- - fast intra-thread communication between multiple
- event loops (with optional fast linux eventfd backend).
- - extremely easy to embed (fully documented, no dependencies,
- autoconf supported but optional).
- - very small codebase, no bloated library, simple code.
- - fully extensible by being able to plug into the event loop,
- integrate other event loops, integrate other event loop users.
- - very little memory use (small watchers, small event loop data).
- - optional C++ interface allowing method and function callbacks
- at no extra memory or runtime overhead.
- - optional Perl interface with similar characteristics (capable
- of running Glib/Gtk2 on libev).
- - support for other languages (multiple C++ interfaces, D, Ruby,
- Python) available from third-parties.
-
- Examples of programs that embed libev: the EV perl module, node.js,
- auditd, rxvt-unicode, gvpe (GNU Virtual Private Ethernet), the
- Deliantra MMORPG server (http://www.deliantra.net/), Rubinius (a
- next-generation Ruby VM), the Ebb web server, the Rev event toolkit.
-
-
-CONTRIBUTORS
-
- libev was written and designed by Marc Lehmann and Emanuele Giaquinta.
-
- The following people sent in patches or made other noteworthy
- contributions to the design (for minor patches, see the Changes
- file. If I forgot to include you, please shout at me, it was an
- accident):
-
- W.C.A. Wijngaards
- Christopher Layne
- Chris Brody

-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN

-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)

-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a

-# Configuration subroutine to validate and canonicalize a configuration type.
-# Supply the specified configuration type as an argument.
-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.
-
-# This file is supposed to be the same for all GNU packages
-# and recognize all the CPU types, system types and aliases
-# that are meaningful with *any* GNU software.
-# Each package is responsible for reporting which valid configurations
-# it does not support. The user should be able to distinguish
-# a failure to support a valid configuration from a meaningless
-# configuration.
-
-# The goal of this file is to map all the various variations of a given
-# machine specification into a single specification in the form:
-# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
-# It is wrong to echo any other type of specification.

-\`configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --infodir=DIR info documentation [DATAROOTDIR/info]

-Optional Features:
- --disable-option-checking ignore unrecognized --enable/--with options
- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --enable-maintainer-mode enable make rules and dependencies not useful
- (and sometimes confusing) to the casual installer
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-sysroot=DIR Search for dependent libraries within DIR
- (or the compiler's sysroot if not specified).
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-.SH "WHAT TO READ WHEN IN A HURRY"
-.IX Header "WHAT TO READ WHEN IN A HURRY"
-This manual tries to be very detailed, but unfortunately, this also makes
-it very long. If you just want to know the basics of libev, I suggest
-reading \*(L"\s-1ANATOMY\s0 \s-1OF\s0 A \s-1WATCHER\s0\*(R", then the \*(L"\s-1EXAMPLE\s0 \s-1PROGRAM\s0\*(R" above and

-.SH "ABOUT LIBEV"
-.IX Header "ABOUT LIBEV"
-Libev is an event loop: you register interest in certain events (such as a
-file descriptor being readable or a timeout occurring), and it will manage
-these event sources and provide your program with events.
-.PP
-To do this, it must take more or less complete control over your process
-(or thread) by executing the \fIevent loop\fR handler, and will then
-communicate events via a callback mechanism.
-.PP
-You register interest in certain events by registering so-called \fIevent
-watchers\fR, which are relatively small C structures you initialise with the
-details of the event, and then hand it over to libev by \fIstarting\fR the
-watcher.
-.SS "\s-1FEATURES\s0"
-.IX Subsection "FEATURES"
-Libev supports \f(CW\*(C`select\*(C'\fR, \f(CW\*(C`poll\*(C'\fR, the Linux-specific \f(CW\*(C`epoll\*(C'\fR, the
-BSD-specific \f(CW\*(C`kqueue\*(C'\fR and the Solaris-specific event port mechanisms
-for file descriptor events (\f(CW\*(C`ev_io\*(C'\fR), the Linux \f(CW\*(C`inotify\*(C'\fR interface

-limited support for fork events (\f(CW\*(C`ev_fork\*(C'\fR).
-.PP
-It also is quite fast (see this
-benchmark <http://libev.schmorp.de/bench.html> comparing it to libevent
-for example).
-.SS "\s-1CONVENTIONS\s0"
-.IX Subsection "CONVENTIONS"
-Libev is very configurable. In this manual the default (and most common)
-configuration will be described, which supports multiple event loops. For
-more info about various configuration options please have a look at
-\&\fB\s-1EMBED\s0\fR section in this manual. If libev was configured without support
-for multiple event loops, then all functions taking an initial argument of
-name \f(CW\*(C`loop\*(C'\fR (which is always of type \f(CW\*(C`struct ev_loop *\*(C'\fR) will not have
-this argument.
-.SS "\s-1TIME\s0 \s-1REPRESENTATION\s0"
-.IX Subsection "TIME REPRESENTATION"
-Libev represents time as a single floating point number, representing
-the (fractional) number of seconds since the (\s-1POSIX\s0) epoch (in practice
-somewhere near the beginning of 1970, details are complicated, don't
-ask). This type is called \f(CW\*(C`ev_tstamp\*(C'\fR, which is what you should use
-too. It usually aliases to the \f(CW\*(C`double\*(C'\fR type in C. When you need to do
-any calculations on it, you should treat it as some floating point value.
-.PP
-Unlike the name component \f(CW\*(C`stamp\*(C'\fR might indicate, it is also used for
-time differences (e.g. delays) throughout libev.
-.SH "ERROR HANDLING"
-.IX Header "ERROR HANDLING"
-Libev knows three classes of errors: operating system errors, usage errors
-and internal errors (bugs).
-.PP
-When libev catches an operating system error it cannot handle (for example
-a system call indicating a condition libev cannot fix), it calls the callback
-set via \f(CW\*(C`ev_set_syserr_cb\*(C'\fR, which is supposed to fix the problem or
-abort. The default is to print a diagnostic message and to call \f(CW\*(C`abort
-()\*(C'\fR.
-.PP
-When libev detects a usage error such as a negative timer interval, then
-it will print a diagnostic message and abort (via the \f(CW\*(C`assert\*(C'\fR mechanism,
-so \f(CW\*(C`NDEBUG\*(C'\fR will disable this checking): these are programming errors in
-the libev caller and need to be fixed there.
-.PP
-Libev also has a few internal error-checking \f(CW\*(C`assert\*(C'\fRions, and also has
-extensive consistency checking code. These do not trigger under normal
-circumstances, as they indicate either a bug in libev or worse.
-.SH "GLOBAL FUNCTIONS"
-.IX Header "GLOBAL FUNCTIONS"
-These functions can be called anytime, even before initialising the
-library in any way.
-.IP "ev_tstamp ev_time ()" 4
-.IX Item "ev_tstamp ev_time ()"
-Returns the current time as libev would use it. Please note that the
-\&\f(CW\*(C`ev_now\*(C'\fR function is usually faster and also often returns the timestamp
-you actually want to know. Also interesting is the combination of
-\&\f(CW\*(C`ev_now_update\*(C'\fR and \f(CW\*(C`ev_now\*(C'\fR.
-.IP "ev_sleep (ev_tstamp interval)" 4
-.IX Item "ev_sleep (ev_tstamp interval)"
-Sleep for the given interval: The current thread will be blocked
-until either it is interrupted or the given time interval has
-passed (approximately \- it might return a bit earlier even if not
-interrupted). Returns immediately if \f(CW\*(C`interval <= 0\*(C'\fR.
-.Sp
-Basically this is a sub-second-resolution \f(CW\*(C`sleep ()\*(C'\fR.
-.Sp
-The range of the \f(CW\*(C`interval\*(C'\fR is limited \- libev only guarantees to work
-with sleep times of up to one day (\f(CW\*(C`interval <= 86400\*(C'\fR).

-you linked against by calling the functions \f(CW\*(C`ev_version_major\*(C'\fR and
-\&\f(CW\*(C`ev_version_minor\*(C'\fR. If you want, you can compare against the global
-symbols \f(CW\*(C`EV_VERSION_MAJOR\*(C'\fR and \f(CW\*(C`EV_VERSION_MINOR\*(C'\fR, which specify the
-version of the library your program was compiled against.
-.Sp
-These version numbers refer to the \s-1ABI\s0 version of the library, not the
-release version.
-.Sp
-Usually, it's a good idea to terminate if the major versions mismatch,
-as this indicates an incompatible change. Minor versions are usually
-compatible to older versions, so a larger minor version alone is usually
-not a problem.
-.Sp
-Example: Make sure we haven't accidentally been linked against the wrong

-\&\f(CW\*(C`ev_supported_backends\*(C'\fR, as for example kqueue is broken on most BSDs
-and will not be auto-detected unless you explicitly request it (assuming
-you know what you are doing). This is the set of backends that libev will
-probe for if you specify no backends explicitly.
-.IP "unsigned int ev_embeddable_backends ()" 4
-.IX Item "unsigned int ev_embeddable_backends ()"
-Returns the set of backends that are embeddable in other event loops. This
-value is platform-specific but can include backends not available on the
-current system. To find which embeddable backends might be supported on
-the current system, you would need to look at \f(CW\*(C`ev_embeddable_backends ()

-.IP "ev_set_allocator (void *(*cb)(void *ptr, long size) throw ())" 4
-.IX Item "ev_set_allocator (void *(*cb)(void *ptr, long size) throw ())"
-Sets the allocation function to use (the prototype is similar \- the
-semantics are identical to the \f(CW\*(C`realloc\*(C'\fR C89/SuS/POSIX function). It is
-used to allocate and free memory (no surprises here). If it returns zero
-when memory needs to be allocated (\f(CW\*(C`size != 0\*(C'\fR), the library might abort
-or take some potentially destructive action.
-.Sp
-Since some systems (at least OpenBSD and Darwin) fail to implement
-correct \f(CW\*(C`realloc\*(C'\fR semantics, libev will use a wrapper around the system
-\&\f(CW\*(C`realloc\*(C'\fR and \f(CW\*(C`free\*(C'\fR functions by default.
-.Sp
-You could override this function in high-availability programs to, say,
-free some memory if it cannot allocate memory, to use a special allocator,
-or even to sleep a while and retry until some memory is available.

-Example: Replace the libev allocator with one that waits a bit and then
-retries (example requires a standards-compliant \f(CW\*(C`realloc\*(C'\fR).

-.SH "FUNCTIONS CONTROLLING EVENT LOOPS"

-An event loop is described by a \f(CW\*(C`struct ev_loop *\*(C'\fR (the \f(CW\*(C`struct\*(C'\fR is
-\&\fInot\fR optional in this case unless libev 3 compatibility is disabled, as
-libev 3 had an \f(CW\*(C`ev_loop\*(C'\fR function colliding with the struct name).
-.PP
-The library knows two types of such loops, the \fIdefault\fR loop, which
-supports child process events, and dynamically created event loops which
-do not.
-.IP "struct ev_loop *ev_default_loop (unsigned int flags)" 4
-.IX Item "struct ev_loop *ev_default_loop (unsigned int flags)"
-This returns the \*(L"default\*(R" event loop object, which is what you should
-normally use when you just need \*(L"the event loop\*(R". Event loop objects and
-the \f(CW\*(C`flags\*(C'\fR parameter are described in more detail in the entry for
-\&\f(CW\*(C`ev_loop_new\*(C'\fR.
-.Sp
-If the default loop is already initialised then this function simply
-returns it (and ignores the flags. If that is troubling you, check
-\&\f(CW\*(C`ev_backend ()\*(C'\fR afterwards). Otherwise it will create it with the given
-flags, which should almost always be \f(CW0\fR, unless the caller is also the
-one calling \f(CW\*(C`ev_run\*(C'\fR or otherwise qualifies as \*(L"the main program\*(R".
-.Sp
-If you don't know what event loop to use, use the one returned from this
-function (or via the \f(CW\*(C`EV_DEFAULT\*(C'\fR macro).
-.Sp
-Note that this function is \fInot\fR thread-safe, so if you want to use it
-from multiple threads, you have to employ some kind of mutex (note also
-that this case is unlikely, as loops cannot be shared easily between
-threads anyway).
-.Sp
-The default loop is the only loop that can handle \f(CW\*(C`ev_child\*(C'\fR watchers,
-and to do this, it always registers a handler for \f(CW\*(C`SIGCHLD\*(C'\fR. If this is
-a problem for your application you can either create a dynamic loop with

-Instead of calling \f(CW\*(C`ev_loop_fork\*(C'\fR manually after a fork, you can also
-make libev check for a fork in each iteration by enabling this flag.
-.Sp
-This works by calling \f(CW\*(C`getpid ()\*(C'\fR on every iteration of the loop,
-and thus this might slow down your event loop if you do a lot of loop
-iterations and little real work, but is usually not noticeable (on my

-.Sp
-The big advantage of this flag is that you can forget about fork (and
-forget about forgetting to tell libev about forking) when you use this

-handling with threads, as long as you properly block signals in your
-threads that are not interested in handling them.
-.Sp
-Signalfd will not be used by default as this changes your signal mask, and

-Use the linux-specific \fIepoll\fR\|(7) interface (for both pre\- and post\-2.6.9

-.Sp
-For few fds, this backend is a bit little slower than poll and select, but
-it scales phenomenally better. While poll and select usually scale like
-O(total_fds) where total_fds is the total number of fds (or the highest
-fd), epoll scales either O(1) or O(active_fds).
-.Sp
-The epoll mechanism deserves honorable mention as the most misdesigned
-of the more advanced event mechanisms: mere annoyances include silently
-dropping file descriptors, requiring a system call per change per file
-descriptor (and unnecessary guessing of parameters), problems with dup,
-returning before the timeout value, resulting in additional iterations
-(and only giving 5ms accuracy while select on the same platform gives
-0.1ms) and so on. The biggest issue is fork races, however \- if a program
-forks then \fIboth\fR parent and child process have to recreate the epoll
-set, which can take considerable time (one syscall per file descriptor)
-and is of course hard to detect.
-.Sp
-Epoll is also notoriously buggy \- embedding epoll fds \fIshould\fR work,
-but of course \fIdoesn't\fR, and epoll just loves to report events for
-totally \fIdifferent\fR file descriptors (even already closed ones, so
-one cannot even remove them from the set) than registered in the set
-(especially on \s-1SMP\s0 systems). Libev tries to counter these spurious
-notifications by employing an additional generation counter and comparing
-that against the events to filter out spurious ones, recreating the set
-when required. Epoll also erroneously rounds down timeouts, but gives you
-no way to know when and by how much, so sometimes you have to busy-wait
-because epoll returns immediately despite a nonzero timeout. And last
-not least, it also refuses to work with some file descriptors which work
-perfectly fine with \f(CW\*(C`select\*(C'\fR (files, many character devices...).
-.Sp
-Epoll is truly the train wreck among event poll mechanisms, a frankenpoll,
-cobbled together in a hurry, no thought to design or interaction with
-others. Oh, the pain, will it ever stop...
-.Sp
-While stopping, setting and starting an I/O watcher in the same iteration
-will result in some caching, there is still a system call per such
-incident (because the same \fIfile descriptor\fR could point to a different
-\&\fIfile description\fR now), so its best to avoid that. Also, \f(CW\*(C`dup ()\*(C'\fR'ed
-file descriptors might not work very well if you register events for both
-file descriptors.
-.Sp
-Best performance from this backend is achieved by not unregistering all
-watchers for a file descriptor until it has been closed, if possible,
-i.e. keep at least one watcher active per fd at all times. Stopping and
-starting a watcher (without re-setting it) also usually doesn't cause
-extra overhead. A fork can both result in spurious notifications as well
-as in libev having to destroy and recreate the epoll object, which can
-take considerable time and thus should be avoided.
-.Sp
-All this means that, in practice, \f(CW\*(C`EVBACKEND_SELECT\*(C'\fR can be as fast or

-These advanced functions influence the time that libev will spend waiting
-for events. Both time intervals are by default \f(CW0\fR, meaning that libev
-will try to invoke timer/periodic callbacks and I/O callbacks with minimum
-latency.
-.Sp
-Setting these to a higher value (the \f(CW\*(C`interval\*(C'\fR \fImust\fR be >= \f(CW0\fR)
-allows libev to delay invocation of I/O and timer/periodic callbacks
-to increase efficiency of loop iterations (or to increase power-saving
-opportunities).
-.Sp
-The idea is that sometimes your program runs just fast enough to handle
-one (or very few) event(s) per loop iteration. While this makes the
-program responsive, it also wastes a lot of \s-1CPU\s0 time to poll for new
-events, especially with backends like \f(CW\*(C`select ()\*(C'\fR which have a high
-overhead for the actual polling but can deliver many events at once.
-.Sp
-By setting a higher \fIio collect interval\fR you allow libev to spend more
-time collecting I/O events, so you can handle more events per iteration,
-at the cost of increasing latency. Timeouts (both \f(CW\*(C`ev_periodic\*(C'\fR and
-\&\f(CW\*(C`ev_timer\*(C'\fR) will not be affected. Setting this to a non-null value will
-introduce an additional \f(CW\*(C`ev_sleep ()\*(C'\fR call into most loop iterations. The
-sleep time ensures that libev will not poll for I/O events more often then
-once per this interval, on average (as long as the host time resolution is
-good enough).
-.Sp
-Likewise, by setting a higher \fItimeout collect interval\fR you allow libev
-to spend more time collecting timeouts, at the expense of increased
-latency/jitter/inexactness (the watcher callback will be called
-later). \f(CW\*(C`ev_io\*(C'\fR watchers will not be affected. Setting this to a non-null
-value will not introduce any overhead in libev.
-.Sp
-Many (busy) programs can usually benefit by setting the I/O collect
-interval to a value near \f(CW0.1\fR or so, which is often enough for
-interactive servers (of course not for games), likewise for timeouts. It
-usually doesn't make much sense to set it to a lower value than \f(CW0.01\fR,
-as this approaches the timing granularity of most systems. Note that if
-you do transactions with the outside world and you can't increase the
-parallelity, then this setting will limit your transaction rate (if you
-need to poll once per transaction and the I/O collect interval is 0.01,
-then you can't do more than 100 transactions per second).
-.Sp
-Setting the \fItimeout collect interval\fR can improve the opportunity for
-saving power, as the program will \*(L"bundle\*(R" timer callback invocations that
-are \*(L"near\*(R" in time together, by delaying some, thus reducing the number of

-watchers and \f(CW\*(C`ev_io_start\*(C'\fR for I/O watchers.
-.PP
-A watcher is an opaque structure that you allocate and register to record

-.Ve
-.PP
-As you can see, you are responsible for allocating the memory for your
-watcher structures (and it is \fIusually\fR a bad idea to do this on the
-stack).
-.PP
-Each watcher has an associated watcher structure (called \f(CW\*(C`struct ev_TYPE\*(C'\fR
-or simply \f(CW\*(C`ev_TYPE\*(C'\fR, as typedefs are provided for all watcher structs).
-.PP
-Each watcher structure must be initialised by a call to \f(CW\*(C`ev_init (watcher
-*, callback)\*(C'\fR, which expects a callback to be provided. This callback is
-invoked each time the event occurs (or, in the case of I/O watchers, each
-time the event loop detects that the file descriptor given is readable
-and/or writable).
-.PP
-Each watcher type further has its own \f(CW\*(C`ev_TYPE_set (watcher *, ...)\*(C'\fR
-macro to configure it, with arguments specific to the watcher type. There
-is also a macro to combine initialisation and setting in one call: \f(CW\*(C`ev_TYPE_init (watcher *, callback, ...)\*(C'\fR.
-.PP
-To make the watcher actually watch out for events, you have to start it
-with a watcher-specific start function (\f(CW\*(C`ev_TYPE_start (loop, watcher
-*)\*(C'\fR), and you can stop watching for events at any time by calling the
-corresponding stop function (\f(CW\*(C`ev_TYPE_stop (loop, watcher *)\*(C'\fR.
-.PP
-As long as your watcher is active (has been started but not stopped) you
-must not touch the values stored in it. Most specifically you must never

-.IX Item "initialised"
-Before a watcher can be registered with the event loop it has to be

-.IP "started/running/active" 4
-.IX Item "started/running/active"
-Once a watcher has been started with a call to \f(CW\*(C`ev_TYPE_start\*(C'\fR it becomes
-property of the event loop, and is actively waiting for events. While in
-this state it cannot be accessed (except in a few documented ways), moved,
-freed or anything else \- the only legal thing is to keep a pointer to it,
-and call libev functions on it that are documented to work on active watchers.
-.IP "pending" 4
-.IX Item "pending"
-If a watcher is active and libev determines that an event it is interested
-in has occurred (such as a timer expiring), it will become pending. It will
-stay in this pending state until either it is stopped or its callback is
-about to be invoked, so it is not normally pending inside the watcher
-callback.
-.Sp
-The watcher might or might not be active while it is pending (for example,
-an expired non-repeating timer can be pending but no longer active). If it
-is stopped, it can be freely accessed (e.g. by calling \f(CW\*(C`ev_TYPE_set\*(C'\fR),
-but it is still property of the event loop at this time, so cannot be
-moved, freed or reused. And if it is active the rules described in the
-previous item still apply.
-.Sp
-It is also possible to feed an event on a watcher that is not active (e.g.
-via \f(CW\*(C`ev_feed_event\*(C'\fR), in which case it becomes pending without being
-active.
-.IP "stopped" 4
-.IX Item "stopped"
-A watcher can be stopped implicitly by libev (in which case it might still
-be pending), or explicitly by calling its \f(CW\*(C`ev_TYPE_stop\*(C'\fR function. The
-latter will clear any pending state the watcher might be in, regardless
-of whether it was active or not, so stopping a watcher explicitly before
-freeing it is often a good idea.
-.Sp
-While stopped (and not pending) the watcher is essentially in the
-initialised state, that is, it can be reused, moved, modified in any way
-you wish (but when you trash the memory block, you need to \f(CW\*(C`ev_TYPE_init\*(C'\fR
-it again).
-.SS "\s-1WATCHER\s0 \s-1PRIORITY\s0 \s-1MODELS\s0"
-.IX Subsection "WATCHER PRIORITY MODELS"
-Many event loops support \fIwatcher priorities\fR, which are usually small
-integers that influence the ordering of event callback invocation
-between watchers in some way, all else being equal.
-.PP
-In libev, Watcher priorities can be set using \f(CW\*(C`ev_set_priority\*(C'\fR. See its
-description for the more technical details such as the actual priority
-range.
-.PP
-There are two common ways how these these priorities are being interpreted
-by event loops:
-.PP
-In the more common lock-out model, higher priorities \*(L"lock out\*(R" invocation
-of lower priority watchers, which means as long as higher priority
-watchers receive events, lower priority watchers are not being invoked.
-.PP
-The less common only-for-ordering model uses priorities solely to order
-callback invocation within a single event loop iteration: Higher priority
-watchers are invoked before lower priority ones, but they all get invoked
-before polling for new events.
-.PP
-Libev uses the second (only-for-ordering) model for all its watchers
-except for idle watchers (which use the lock-out model).
-.PP
-The rationale behind this is that implementing the lock-out model for
-watchers is not well supported by most kernel interfaces, and most event
-libraries will just poll for the same events again and again as long as
-their callbacks have not been executed, which is very inefficient in the
-common case of one high-priority watcher locking out a mass of lower
-priority ones.
-.PP
-Static (ordering) priorities are most useful when you have two or more
-watchers handling the same resource: a typical usage example is having an
-\&\f(CW\*(C`ev_io\*(C'\fR watcher to receive data, and an associated \f(CW\*(C`ev_timer\*(C'\fR to handle
-timeouts. Under load, data might be received while the program handles
-other jobs, but since timers normally get invoked first, the timeout
-handler will be executed before checking for data. In that case, giving
-the timer a lower priority than the I/O watcher ensures that I/O will be
-handled first even under adverse conditions (which is usually, but not
-always, what you want).
-.PP
-Since idle watchers use the \*(L"lock-out\*(R" model, meaning that idle watchers
-will only be executed when no same or higher priority watchers have
-received events, they can be used to implement the \*(L"lock-out\*(R" model when
-required.
-.PP
-For example, to emulate how many other event libraries handle priorities,
-you can associate an \f(CW\*(C`ev_idle\*(C'\fR watcher to each such watcher, and in
-the normal watcher callback, you just start the idle watcher. The real
-processing is done in the idle watcher callback. This causes libev to
-continuously poll and process kernel event data for the watcher, but when
-the lock-out case is known to be rare (which in turn is rare :), this is
-workable.
-.PP
-Usually, however, the lock-out model implemented that way will perform
-miserably under the type of load it was designed to handle. In that case,
-it might be preferable to stop the real watcher before starting the
-idle watcher, so the kernel will not have to process the event in case
-the actual processing will be delayed for considerable time.
-.PP
-Here is an example of an I/O watcher that should run at a strictly lower
-priority than the default, and which should only process data when no
-other events are pending:
-.PP
-.Vb 2
-\& ev_idle idle; // actual processing watcher
-\& ev_io io; // actual event watcher
-\&
-\& static void
-\& io_cb (EV_P_ ev_io *w, int revents)
-\& {
-\& // stop the I/O watcher, we received the event, but
-\& // are not yet ready to handle it.
-\& ev_io_stop (EV_A_ w);
-\&
-\& // start the idle watcher to handle the actual event.
-\& // it will not be executed as long as other watchers
-\& // with the default priority are receiving events.
-\& ev_idle_start (EV_A_ &idle);
-\& }
-\&
-\& static void
-\& idle_cb (EV_P_ ev_idle *w, int revents)

-\& ev_idle_init (&idle, idle_cb);
-\& ev_io_init (&io, io_cb, STDIN_FILENO, EV_READ);
-\& ev_io_start (EV_DEFAULT_ &io);
-.Ve
-.PP
-In the \*(L"real\*(R" world, it might also be beneficial to start a timer, so that
-low-priority connections can not be locked out forever under load. This
-enables your program to keep a lower latency for important connections
-during short periods of high load, while not completely locking out less
-important ones.
-.SH "WATCHER TYPES"
-.IX Header "WATCHER TYPES"
-This section describes each watcher in detail, but will not repeat
-information given in the last section. Any initialisation/set macros,
-functions and members specific to the watcher type are explained.
-.PP
-Members are additionally marked with either \fI[read\-only]\fR, meaning that,
-while the watcher is active, you can look at the member and expect some
-sensible content, but you must not modify it (you can modify it while the
-watcher is stopped to your hearts content), or \fI[read\-write]\fR, which
-means you can expect it to have some sensible content while the watcher
-is active, but you can also modify it. Modifying it may not do something
-sensible or take immediate effect (or do anything at all), but libev will
-not crash or malfunction in any way.
-.ie n .SS """ev_io"" \- is this file descriptor readable or writable?"
-.el .SS "\f(CWev_io\fP \- is this file descriptor readable or writable?"
-.IX Subsection "ev_io - is this file descriptor readable or writable?"
-I/O watchers check whether a file descriptor is readable or writable
-in each iteration of the event loop, or, more precisely, when reading
-would not block the process and writing would at least be able to write
-some data. This behaviour is called level-triggering because you keep
-receiving events as long as the condition persists. Remember you can stop
-the watcher if you don't want to act on the event and neither want to
-receive future events.
-.PP
-In general you can register as many read and/or write event watchers per
-fd as you want (as long as you don't confuse yourself). Setting all file
-descriptors to non-blocking mode is also usually a good idea (but not
-required if you know what you are doing).
-.PP
-Another thing you have to watch out for is that it is quite easy to
-receive \*(L"spurious\*(R" readiness notifications, that is, your callback might
-be called with \f(CW\*(C`EV_READ\*(C'\fR but a subsequent \f(CW\*(C`read\*(C'\fR(2) will actually block
-because there is no data. It is very easy to get into this situation even
-with a relatively standard program structure. Thus it is best to always
-use non-blocking I/O: An extra \f(CW\*(C`read\*(C'\fR(2) returning \f(CW\*(C`EAGAIN\*(C'\fR is far
-preferable to a program hanging until some data arrives.
-.PP
-If you cannot run the fd in non-blocking mode (for example you should
-not play around with an Xlib connection), then you have to separately
-re-test whether a file descriptor is really ready with a known-to-be good
-interface such as poll (fortunately in the case of Xlib, it already does
-this on its own, so its quite safe to use). Some people additionally
-use \f(CW\*(C`SIGALRM\*(C'\fR and an interval timer, just to be sure you won't block
-indefinitely.
-.PP
-But really, best use non-blocking mode.
-.PP
-\fIThe special problem of disappearing file descriptors\fR
-.IX Subsection "The special problem of disappearing file descriptors"
-.PP
-Some backends (e.g. kqueue, epoll) need to be told about closing a file
-descriptor (either due to calling \f(CW\*(C`close\*(C'\fR explicitly or any other means,
-such as \f(CW\*(C`dup2\*(C'\fR). The reason is that you register interest in some file
-descriptor, but when it goes away, the operating system will silently drop
-this interest. If another file descriptor with the same number then is
-registered with libev, there is no efficient way to see that this is, in
-fact, a different file descriptor.
-.PP
-To avoid having to explicitly tell libev about such cases, libev follows
-the following policy: Each time \f(CW\*(C`ev_io_set\*(C'\fR is being called, libev
-will assume that this is potentially a new file descriptor, otherwise
-it is assumed that the file descriptor stays the same. That means that
-you \fIhave\fR to call \f(CW\*(C`ev_io_set\*(C'\fR (or \f(CW\*(C`ev_io_init\*(C'\fR) when you change the
-descriptor even if the file descriptor number itself did not change.
-.PP
-This is how one would do it normally anyway, the important point is that
-the libev application should not optimise around libev but should leave
-optimisations to libev.
-.PP
-\fIThe special problem of dup'ed file descriptors\fR
-.IX Subsection "The special problem of dup'ed file descriptors"
-.PP
-Some backends (e.g. epoll), cannot register events for file descriptors,
-but only events for the underlying file descriptions. That means when you
-have \f(CW\*(C`dup ()\*(C'\fR'ed file descriptors or weirder constellations, and register
-events for them, only one file descriptor might actually receive events.
-.PP
-There is no workaround possible except not registering events
-for potentially \f(CW\*(C`dup ()\*(C'\fR'ed file descriptors, or to resort to
-\&\f(CW\*(C`EVBACKEND_SELECT\*(C'\fR or \f(CW\*(C`EVBACKEND_POLL\*(C'\fR.
-.PP
-\fIThe special problem of files\fR
-.IX Subsection "The special problem of files"
-.PP
-Many people try to use \f(CW\*(C`select\*(C'\fR (or libev) on file descriptors
-representing files, and expect it to become ready when their program
-doesn't block on disk accesses (which can take a long time on their own).
-.PP
-However, this cannot ever work in the \*(L"expected\*(R" way \- you get a readiness
-notification as soon as the kernel knows whether and how much data is
-there, and in the case of open files, that's always the case, so you
-always get a readiness notification instantly, and your read (or possibly
-write) will still block on the disk I/O.
-.PP
-Another way to view it is that in the case of sockets, pipes, character
-devices and so on, there is another party (the sender) that delivers data
-on its own, but in the case of files, there is no such thing: the disk
-will not send data on its own, simply because it doesn't know what you
-wish to read \- you would first have to request some data.
-.PP
-Since files are typically not-so-well supported by advanced notification
-mechanism, libev tries hard to emulate \s-1POSIX\s0 behaviour with respect
-to files, even though you should not use it. The reason for this is
-convenience: sometimes you want to watch \s-1STDIN\s0 or \s-1STDOUT\s0, which is
-usually a tty, often a pipe, but also sometimes files or special devices
-(for example, \f(CW\*(C`epoll\*(C'\fR on Linux works with \fI/dev/random\fR but not with
-\&\fI/dev/urandom\fR), and even though the file might better be served with
-asynchronous I/O instead of with non-blocking I/O, it is still useful when
-it \*(L"just works\*(R" instead of freezing.
-.PP
-So avoid file descriptors pointing to files when you know it (e.g. use
-libeio), but use them when it is convenient, e.g. for \s-1STDIN/STDOUT\s0, or
-when you rarely read from a file instead of from a socket, and want to
-reuse the same code path.
-.PP
-\fIThe special problem of fork\fR
-.IX Subsection "The special problem of fork"
-.PP
-Some backends (epoll, kqueue) do not support \f(CW\*(C`fork ()\*(C'\fR at all or exhibit
-useless behaviour. Libev fully supports fork, but needs to be told about
-it in the child if you want to continue to use it in the child.
-.PP
-To support fork in your child processes, you have to call \f(CW\*(C`ev_loop_fork
-()\*(C'\fR after a fork in the child, enable \f(CW\*(C`EVFLAG_FORKCHECK\*(C'\fR, or resort to
-\&\f(CW\*(C`EVBACKEND_SELECT\*(C'\fR or \f(CW\*(C`EVBACKEND_POLL\*(C'\fR.
-.PP
-\fIThe special problem of \s-1SIGPIPE\s0\fR
-.IX Subsection "The special problem of SIGPIPE"
-.PP
-While not really specific to libev, it is easy to forget about \f(CW\*(C`SIGPIPE\*(C'\fR:
-when writing to a pipe whose other end has been closed, your program gets
-sent a \s-1SIGPIPE\s0, which, by default, aborts your program. For most programs
-this is sensible behaviour, for daemons, this is usually undesirable.
-.PP
-So when you encounter spurious, unexplained daemon exits, make sure you
-ignore \s-1SIGPIPE\s0 (and maybe make sure you log the exit status of your daemon
-somewhere, as that would have given you a big clue).
-.PP
-\fIThe special problem of \fIaccept()\fIing when you can't\fR
-.IX Subsection "The special problem of accept()ing when you can't"
-.PP
-Many implementations of the \s-1POSIX\s0 \f(CW\*(C`accept\*(C'\fR function (for example,
-found in post\-2004 Linux) have the peculiar behaviour of not removing a
-connection from the pending queue in all error cases.
-.PP
-For example, larger servers often run out of file descriptors (because
-of resource limits), causing \f(CW\*(C`accept\*(C'\fR to fail with \f(CW\*(C`ENFILE\*(C'\fR but not
-rejecting the connection, leading to libev signalling readiness on
-the next iteration again (the connection still exists after all), and
-typically causing the program to loop at 100% \s-1CPU\s0 usage.
-.PP
-Unfortunately, the set of errors that cause this issue differs between
-operating systems, there is usually little the app can do to remedy the
-situation, and no known thread-safe method of removing the connection to
-cope with overload is known (to me).
-.PP
-One of the easiest ways to handle this situation is to just ignore it
-\&\- when the program encounters an overload, it will just loop until the
-situation is over. While this is a form of busy waiting, no \s-1OS\s0 offers an
-event-based way to handle this situation, so it's the best one can do.
-.PP
-A better way to handle the situation is to log any errors other than
-\&\f(CW\*(C`EAGAIN\*(C'\fR and \f(CW\*(C`EWOULDBLOCK\*(C'\fR, making sure not to flood the log with such
-messages, and continue as usual, which at least gives the user an idea of
-what could be wrong (\*(L"raise the ulimit!\*(R"). For extra points one could stop
-the \f(CW\*(C`ev_io\*(C'\fR watcher on the listening fd \*(L"for a while\*(R", which reduces \s-1CPU\s0
-usage.
-.PP
-If your program is single-threaded, then you could also keep a dummy file
-descriptor for overload situations (e.g. by opening \fI/dev/null\fR), and
-when you run into \f(CW\*(C`ENFILE\*(C'\fR or \f(CW\*(C`EMFILE\*(C'\fR, close it, run \f(CW\*(C`accept\*(C'\fR,
-close that fd, and create a new dummy fd. This will gracefully refuse
-clients under typical overload conditions.
-.PP
-The last way to handle it is to simply log the error and \f(CW\*(C`exit\*(C'\fR, as
-is often done with \f(CW\*(C`malloc\*(C'\fR failures, but this results in an easy
-opportunity for a DoS attack.

-.Sp
-In this case, it would be more efficient to leave the \f(CW\*(C`ev_timer\*(C'\fR alone,

-.Ve
-.Sp
-To summarise the callback: first calculate in how many seconds the
-timeout will occur (by calculating the absolute time when it would occur,
-\&\f(CW\*(C`last_activity + timeout\*(C'\fR, and subtracting the current time, \f(CW\*(C`ev_now
-(EV_A)\*(C'\fR from that).
-.Sp
-If this value is negative, then we are already past the timeout, i.e. we
-timed out, and need to do whatever is needed in this case.
-.Sp
-Otherwise, we now the earliest time at which the timeout would trigger,
-and simply start the timer with this timeout value.
-.Sp
-In other words, each time the callback is invoked it will check whether
-the timeout occurred. If not, it will simply reschedule itself to check
-again at the earliest time it could time out. Rinse. Repeat.
-.Sp
-This scheme causes more callback invocations (about one every 60 seconds
-minus half the average time between activity), but virtually no calls to
-libev to change the timeout.
-.Sp
-To start the machinery, simply initialise the watcher and set
-\&\f(CW\*(C`last_activity\*(C'\fR to the current time (meaning there was some activity just
-now), then call the callback, which will \*(L"do the right thing\*(R" and start
-the timer:
-.Sp
-.Vb 3
-\& last_activity = ev_now (EV_A);
-\& ev_init (&timer, callback);
-\& callback (EV_A_ &timer, 0);
-.Ve
-.Sp
-When there is some activity, simply store the current time in
-\&\f(CW\*(C`last_activity\*(C'\fR, no libev calls at all:
-.Sp
-.Vb 2
-\& if (activity detected)
-\& last_activity = ev_now (EV_A);
-.Ve
-.Sp
-When your timeout value changes, then the timeout can be changed by simply
-providing a new value, stopping the timer and calling the callback, which
-will again do the right thing (for example, time out immediately :).
-.Sp
-.Vb 3
-\& timeout = new_value;
-\& ev_timer_stop (EV_A_ &timer);
-\& callback (EV_A_ &timer, 0);
-.Ve
-.Sp

-time-out is unlikely to be triggered, much more efficient.

-.IX Item "4. Wee, just use a double-linked list for your timeouts."
-If there is not one request, but many thousands (millions...), all

-When starting the timeout, calculate the timeout value and put the timeout

-.Sp
-This way, one can manage an unlimited number of timeouts in O(1) time for

-\fIThe special problem of being too early\fR
-.IX Subsection "The special problem of being too early"
-.PP
-If you ask a timer to call your callback after three seconds, then
-you expect it to be invoked after three seconds \- but of course, this
-cannot be guaranteed to infinite precision. Less obviously, it cannot be
-guaranteed to any precision by libev \- imagine somebody suspending the
-process with a \s-1STOP\s0 signal for a few hours for example.
-.PP
-So, libev tries to invoke your callback as soon as possible \fIafter\fR the
-delay has occurred, but cannot guarantee this.
-.PP
-A less obvious failure mode is calling your callback too early: many event
-loops compare timestamps with a \*(L"elapsed delay >= requested delay\*(R", but
-this can cause your callback to be invoked much earlier than you would
-expect.
-.PP
-To see why, imagine a system with a clock that only offers full second
-resolution (think windows if you can't come up with a broken enough \s-1OS\s0
-yourself). If you schedule a one-second timer at the time 500.9, then the
-event loop will schedule your timeout to elapse at a system time of 500
-(500.9 truncated to the resolution) + 1, or 501.
-.PP
-If an event library looks at the timeout 0.1s later, it will see \*(L"501 >=
-501\*(R" and invoke the callback 0.1s after it was started, even though a
-one-second delay was requested \- this is being \*(L"too early\*(R", despite best
-intentions.
-.PP
-This is the reason why libev will never invoke the callback if the elapsed
-delay equals the requested delay, but only when the elapsed delay is
-larger than the requested delay. In the example above, libev would only invoke
-the callback at system time 502, or 1.1s after the timer was started.
-.PP
-So, while libev cannot guarantee that your callback will be invoked
-exactly when requested, it \fIcan\fR and \fIdoes\fR guarantee that the requested
-delay has actually elapsed, or in other words, it always errs on the \*(L"too
-late\*(R" side of things.
-.PP
-\fIThe special problem of time updates\fR
-.IX Subsection "The special problem of time updates"
-.PP
-Establishing the current time is a costly operation (it usually takes
-at least one system call): \s-1EV\s0 therefore updates its idea of the current
-time only before and after \f(CW\*(C`ev_run\*(C'\fR collects new events, which causes a
-growing difference between \f(CW\*(C`ev_now ()\*(C'\fR and \f(CW\*(C`ev_time ()\*(C'\fR when handling
-lots of events in one iteration.
-.PP
-The relative timeouts are calculated relative to the \f(CW\*(C`ev_now ()\*(C'\fR
-time. This is usually the right thing as this timestamp refers to the time
-of the event triggering whatever timeout you are modifying/starting. If
-you suspect event processing to be delayed and you \fIneed\fR to base the
-timeout on the current time, use something like this to adjust for this:
-.PP
-.Vb 1
-\& ev_timer_set (&timer, after + ev_now () \- ev_time (), 0.);
-.Ve
-.PP
-If the event loop is suspended for a long time, you can also force an

-()\*(C'\fR.
-.PP
-\fIThe special problem of unsynchronised clocks\fR
-.IX Subsection "The special problem of unsynchronised clocks"
-.PP
-Modern systems have a variety of clocks \- libev itself uses the normal
-\&\*(L"wall clock\*(R" clock and, if available, the monotonic clock (to avoid time
-jumps).
-.PP
-Neither of these clocks is synchronised with each other or any other clock
-on the system, so \f(CW\*(C`ev_time ()\*(C'\fR might return a considerably different time
-than \f(CW\*(C`gettimeofday ()\*(C'\fR or \f(CW\*(C`time ()\*(C'\fR. On a GNU/Linux system, for example,
-a call to \f(CW\*(C`gettimeofday\*(C'\fR might return a second count that is one higher
-than a directly following call to \f(CW\*(C`time\*(C'\fR.
-.PP
-The moral of this is to only compare libev-related timestamps with
-\&\f(CW\*(C`ev_time ()\*(C'\fR and \f(CW\*(C`ev_now ()\*(C'\fR, at least if you want better precision than
-a second or so.
-.PP
-One more problem arises due to this lack of synchronisation: if libev uses
-the system monotonic clock and you compare timestamps from \f(CW\*(C`ev_time\*(C'\fR
-or \f(CW\*(C`ev_now\*(C'\fR from when you started your timer and when your callback is
-invoked, you will find that sometimes the callback is a bit \*(L"early\*(R".
-.PP
-This is because \f(CW\*(C`ev_timer\*(C'\fRs work in real time, not wall clock time, so
-libev makes sure your callback is not invoked before the delay happened,
-\&\fImeasured according to the real time\fR, not the system clock.
-.PP
-If your timeouts are based on a physical timescale (e.g. \*(L"time out this
-connection after 100 seconds\*(R") then this shouldn't bother you as it is
-exactly the right behaviour.
-.PP
-If you want to compare wall clock/system timestamps to your timers, then
-you need to use \f(CW\*(C`ev_periodic\*(C'\fRs, as these are based on the wall clock
-time, where your comparisons will always generate correct results.

-\fIThe special problems of suspended animation\fR
-.IX Subsection "The special problems of suspended animation"
-.PP
-When you leave the server world it is quite customary to hit machines that
-can suspend/hibernate \- what happens to the clocks during such a suspend?
-.PP
-Some quick tests made with a Linux 2.6.28 indicate that a suspend freezes
-all processes, while the clocks (\f(CW\*(C`times\*(C'\fR, \f(CW\*(C`CLOCK_MONOTONIC\*(C'\fR) continue
-to run until the system is suspended, but they will not advance while the
-system is suspended. That means, on resume, it will be as if the program
-was frozen for a few seconds, but the suspend time will not be counted
-towards \f(CW\*(C`ev_timer\*(C'\fR when a monotonic clock source is used. The real time
-clock advanced as expected, but if it is used as sole clocksource, then a
-long suspend would be detected as a time jump by libev, and timers would
-be adjusted accordingly.
-.PP
-I would not be surprised to see different behaviour in different between
-operating systems, \s-1OS\s0 versions or even different hardware.
-.PP
-The other form of suspend (job control, or sending a \s-1SIGSTOP\s0) will see a
-time jump in the monotonic clocks and the realtime clock. If the program
-is suspended for a very long time, and monotonic clock sources are in use,
-then you can expect \f(CW\*(C`ev_timer\*(C'\fRs to expire as the full suspension time
-will be counted towards the timers. When no monotonic clock source is in
-use, then libev will again assume a timejump and adjust accordingly.
-.PP
-It might be beneficial for this latter case to call \f(CW\*(C`ev_suspend\*(C'\fR
-and \f(CW\*(C`ev_resume\*(C'\fR in code that handles \f(CW\*(C`SIGTSTP\*(C'\fR, to at least get

-Unlike \f(CW\*(C`ev_timer\*(C'\fR, periodic watchers are not based on real time (or
-relative time, the physical time that passes) but on wall clock time
-(absolute time, the thing you can read on your calender or clock). The

-not a delay) and then reset your system clock to January of the previous

-.PP
-\&\f(CW\*(C`ev_periodic\*(C'\fR watchers can also be used to implement vastly more complex

-.IP "\(bu" 4
-repeating interval timer (offset = offset within interval, interval > 0, reschedule_cb = 0)

-In this mode the watcher will always be scheduled to time out at the next

-negative) and then repeat, regardless of any time jumps. The \f(CW\*(C`offset\*(C'\fR
-argument is merely an offset into the \f(CW\*(C`interval\*(C'\fR periods.
-.Sp
-This can be used to create timers that do not drift with respect to the

-Another way to think about it (for the mathematically inclined) is that

-\fI\s-1ABI\s0 Issues (Largefile Support)\fR
-.IX Subsection "ABI Issues (Largefile Support)"
-.PP
-Libev by default (unless the user overrides this) uses the default

-support disabled by default, you get the 32 bit version of the stat
-structure. When using the library from programs that change the \s-1ABI\s0 to
-use 64 bit file offsets the programs will fail. In that case you have to
-compile libev with the same flags to get binary compatibility. This is
-obviously the case with any flags that change the \s-1ABI\s0, but the problem is
-most noticeably displayed with ev_stat and large file support.
-.PP
-The solution for this is to lobby your distribution maker to make large
-file interfaces available by default (as e.g. FreeBSD does) and not
-optional. Libev cannot simply switch on large file support because it has
-to exchange stat structures with application programs compiled using the
-default compilation environment.

-\fIInotify and Kqueue\fR
-.IX Subsection "Inotify and Kqueue"
-.PP
-When \f(CW\*(C`inotify (7)\*(C'\fR support has been compiled into libev and present at
-runtime, it will be used to speed up change detection where possible. The
-inotify descriptor will be created lazily when the first \f(CW\*(C`ev_stat\*(C'\fR
-watcher is being started.
-.PP
-Inotify presence does not change the semantics of \f(CW\*(C`ev_stat\*(C'\fR watchers
-except that changes might be detected earlier, and in some cases, to avoid
-making regular \f(CW\*(C`stat\*(C'\fR calls. Even in the presence of inotify support
-there are many cases where libev has to resort to regular \f(CW\*(C`stat\*(C'\fR polling,
-but as long as kernel 2.6.25 or newer is used (2.6.24 and older have too
-many bugs), the path exists (i.e. stat succeeds), and the path resides on
-a local filesystem (libev currently assumes only ext2/3, jfs, reiserfs and
-xfs are fully working) libev usually gets away without polling.
-.PP
-There is no support for kqueue, as apparently it cannot be used to
-implement this functionality, due to the requirement of having a file
-descriptor open on the object at all times, and detecting renames, unlinks
-etc. is difficult.
-.PP
-\fI\f(CI\*(C`stat ()\*(C'\fI is a synchronous operation\fR
-.IX Subsection "stat () is a synchronous operation"
-.PP
-Libev doesn't normally do any kind of I/O itself, and so is not blocking
-the process. The exception are \f(CW\*(C`ev_stat\*(C'\fR watchers \- those call \f(CW\*(C`stat
-()\*(C'\fR, which is a synchronous operation.
-.PP
-For local paths, this usually doesn't matter: unless the system is very
-busy or the intervals between stat's are large, a stat call will be fast,
-as the path data is usually in memory already (except when starting the
-watcher).
-.PP
-For networked file systems, calling \f(CW\*(C`stat ()\*(C'\fR can block an indefinite
-time due to network issues, and even under good conditions, a stat call
-often takes multiple milliseconds.

-\fIThe special problem of stat time resolution\fR
-.IX Subsection "The special problem of stat time resolution"
-.PP
-The \f(CW\*(C`stat ()\*(C'\fR system call only supports full-second resolution portably,
-and even on systems where the resolution is higher, most file systems
-still only support whole seconds.
-.PP
-That means that, if the time is the only thing that changes, you can
-easily miss updates: on the first update, \f(CW\*(C`ev_stat\*(C'\fR detects a change and
-calls your callback, which does something. When there is another update
-within the same second, \f(CW\*(C`ev_stat\*(C'\fR will be unable to detect unless the
-stat data does change in other ways (e.g. file size).
-.PP
-The solution to this is to delay acting on a change for slightly more
-than a second (or till slightly after the next full second boundary), using
-a roughly one-second-delay \f(CW\*(C`ev_timer\*(C'\fR (e.g. \f(CW\*(C`ev_timer_set (w, 0., 1.02);
-ev_timer_again (loop, w)\*(C'\fR).
-.PP
-The \f(CW.02\fR offset is added to work around small timing inconsistencies
-of some operating systems (where the second counter of the current time
-might be be delayed. One such system is the Linux kernel, where a call to
-\&\f(CW\*(C`gettimeofday\*(C'\fR might return a timestamp with a full second later than
-a subsequent \f(CW\*(C`time\*(C'\fR call \- if the equivalent of \f(CW\*(C`time ()\*(C'\fR is used to
-update file times then there will be a small window where the kernel uses

-Prepare and check watchers are often (but not always) used in pairs:

-You \fImust not\fR call \f(CW\*(C`ev_run\*(C'\fR or similar functions that enter
-the current event loop from either \f(CW\*(C`ev_prepare\*(C'\fR or \f(CW\*(C`ev_check\*(C'\fR
-watchers. Other loops than the current one are fine, however. The
-rationale behind this is that you do not need to check for recursion in
-those watchers, i.e. the sequence will always be \f(CW\*(C`ev_prepare\*(C'\fR, blocking,
-\&\f(CW\*(C`ev_check\*(C'\fR so if you have one watcher of each kind they will always be
-called in pairs bracketing the blocking call.
-.PP
-Their main purpose is to integrate other event mechanisms into libev and
-their use is somewhat advanced. They could be used, for example, to track
-variable changes, implement your own watchers, integrate net-snmp or a
-coroutine library and lots more. They are also occasionally useful if
-you cache some data and want to flush it before blocking (for example,
-in X programs you might want to do an \f(CW\*(C`XFlush ()\*(C'\fR in an \f(CW\*(C`ev_prepare\*(C'\fR
-watcher).
-.PP
-This is done by examining in each prepare call which file descriptors
-need to be watched by the other library, registering \f(CW\*(C`ev_io\*(C'\fR watchers
-for them and starting an \f(CW\*(C`ev_timer\*(C'\fR watcher for any timeouts (many
-libraries provide exactly this functionality). Then, in the check watcher,
-you check for any events that occurred (by checking the pending status
-of all watchers and stopping them) and call back into the library. The
-I/O and timer callbacks will never actually be called (but must be valid
-nevertheless, because you never know, you know?).
-.PP
-As another example, the Perl Coro module uses these hooks to integrate
-coroutines into libev programs, by yielding to other active coroutines
-during each prepare and only letting the process block if no coroutines
-are ready to run (it's actually more complicated: it only runs coroutines
-with priority higher than or equal to the event loop and one coroutine
-of lower priority, but only once, using idle watchers to keep the event
-loop from blocking if lower-priority coroutines are active, thus mapping
-low-priority coroutines to idle/background tasks).
-.PP
-When used for this purpose, it is recommended to give \f(CW\*(C`ev_check\*(C'\fR watchers
-highest (\f(CW\*(C`EV_MAXPRI\*(C'\fR) priority, to ensure that they are being run before
-any other watchers after the poll (this doesn't matter for \f(CW\*(C`ev_prepare\*(C'\fR
-watchers).
-.PP
-Also, \f(CW\*(C`ev_check\*(C'\fR watchers (and \f(CW\*(C`ev_prepare\*(C'\fR watchers, too) should not
-activate (\*(L"feed\*(R") events into libev. While libev fully supports this, they
-might get executed before other \f(CW\*(C`ev_check\*(C'\fR watchers did their job. As
-\&\f(CW\*(C`ev_check\*(C'\fR watchers are often used to embed other (non-libev) event
-loops those other event loops might be in an unusable state until their
-\&\f(CW\*(C`ev_check\*(C'\fR watcher ran (always remind yourself to coexist peacefully with
-others).

-\&\f(CW\*(C`ev_check\*(C'\fR (and less often also \f(CW\*(C`ev_prepare\*(C'\fR) watchers can also be

-This is a rather advanced watcher type that lets you embed one event loop
-into another (currently only \f(CW\*(C`ev_io\*(C'\fR events are supported in the embedded
-loop, other types of watchers might be handled in a delayed or incorrect
-fashion and must not be used).
-.PP
-There are primarily two reasons you would want that: work around bugs and
-prioritise I/O.
-.PP
-As an example for a bug workaround, the kqueue backend might only support
-sockets on some platform, so it is unusable as generic backend, but you
-still want to make use of it because you have many sockets and it scales
-so nicely. In this case, you would create a kqueue-based loop and embed
-it into your default loop (which might use e.g. poll). Overall operation
-will be a bit slower because first libev has to call \f(CW\*(C`poll\*(C'\fR and then
-\&\f(CW\*(C`kevent\*(C'\fR, but at least you can use both mechanisms for what they are
-best: \f(CW\*(C`kqueue\*(C'\fR for scalable sockets and \f(CW\*(C`poll\*(C'\fR if you want it to work :)
-.PP
-As for prioritising I/O: under rare circumstances you have the case where
-some fds have to be watched and handled very quickly (with low latency),
-and even priorities and idle watchers might have too much overhead. In
-this case you would put all the high priority stuff in one loop and all
-the rest in a second one, and embed the second one in the first.
-.PP
-As long as the watcher is active, the callback will be invoked every
-time there might be events pending in the embedded loop. The callback
-must then call \f(CW\*(C`ev_embed_sweep (mainloop, watcher)\*(C'\fR to make a single
-sweep and invoke their callbacks (the callback doesn't need to invoke the
-\&\f(CW\*(C`ev_embed_sweep\*(C'\fR function directly, it could also start an idle watcher
-to give the embedded loop strictly lower priority for example).
-.PP
-You can also set the callback to \f(CW0\fR, in which case the embed watcher
-will automatically execute the embedded loop sweep whenever necessary.
-.PP
-Fork detection will be handled transparently while the \f(CW\*(C`ev_embed\*(C'\fR watcher
-is active, i.e., the embedded loop will automatically be forked when the
-embedding loop forks. In other cases, the user is responsible for calling
-\&\f(CW\*(C`ev_loop_fork\*(C'\fR on the embedded loop.
-.PP
-Unfortunately, not all backends are embeddable: only the ones returned by
-\&\f(CW\*(C`ev_embeddable_backends\*(C'\fR are, which, unfortunately, does not include any
-portable one.
-.PP
-So when you want to use this feature you will always have to be prepared

-.PP
-For a real-world example, see the \f(CW\*(C`EV::Loop::Async\*(C'\fR perl module,

-languages).
-.PP
-The example uses a pthread mutex to protect the loop data, a condition
-variable to wait for callback invocations, an async watcher to notify the
-event loop thread and an unspecified mechanism to wake up the main thread.
-.PP
-First, you need to associate some data with the event loop:
-.PP
-.Vb 6

-\& pthread_create (&u\->tid, 0, l_run, EV_A);
-\& }
-.Ve
-.PP
-The callback for the \f(CW\*(C`ev_async\*(C'\fR watcher does nothing: the watcher is used
-solely to wake up the event loop so it takes notice of any new watchers

-.Vb 5
-\& static void

-The \f(CW\*(C`l_release\*(C'\fR and \f(CW\*(C`l_acquire\*(C'\fR callbacks simply unlock/lock the mutex

-\&
-\& return 0;

-.Ve
-.PP
-Instead of invoking all pending watchers, the \f(CW\*(C`l_invoke\*(C'\fR callback will
-signal the main thread via some unspecified mechanism (signals? pipe
-writes? \f(CW\*(C`Async::Interrupt\*(C'\fR?) and then waits until all pending watchers
-have been called (in a while loop because a) spurious wakeups are possible
-and b) skipping inter-thread-communication when there are no pending

-\& pthread_mutex_unlock (&u\->lock);
-\& }
-.Ve
-.PP
-Whenever you want to start/stop a watcher or do other modifications to an
-event loop, you will now have to lock:
-.PP
-.Vb 2
-\& ev_timer timeout_watcher;
-\& userdata *u = ev_userdata (EV_A);

-.Ve
-.PP
-Note that sending the \f(CW\*(C`ev_async\*(C'\fR watcher is required because otherwise
-an event loop currently blocking in the kernel will have no knowledge
-about the newly added timer. By waking up the loop it will pick up any new
-watchers in the next event loop iteration.

-You can do similar tricks if you have, say, threads with an event queue \-

-The normal C \s-1API\s0 should work fine when used from \*(C+: both ev.h and the
-libev sources can be compiled as \*(C+. Therefore, code that uses the C \s-1API\s0
-will work fine.
-.PP
-Proper exception specifications might have to be added to callbacks passed
-to libev: exceptions may be thrown only from watcher callbacks, all
-other callbacks (allocator, syserr, loop acquire/release and periodic
-reschedule callbacks) must not throw exceptions, and might need a \f(CW\*(C`throw
-()\*(C'\fR specification. If you have code that needs to be compiled as both C
-and \*(C+ you can use the \f(CW\*(C`EV_THROW\*(C'\fR macro for this:
-.PP
-.Vb 6
-\& static void
-\& fatal_error (const char *msg) EV_THROW
-\& {
-\& perror (msg);
-\& abort ();
-\& }
-\&
-\& ...

-.Ve
-.PP
-The only \s-1API\s0 functions that can currently throw exceptions are \f(CW\*(C`ev_run\*(C'\fR,
-\&\f(CW\*(C`ev_invoke\*(C'\fR, \f(CW\*(C`ev_invoke_pending\*(C'\fR and \f(CW\*(C`ev_loop_destroy\*(C'\fR (the latter
-because it runs cleanup watchers).
-.PP
-Throwing exceptions in watcher callbacks is only supported if libev itself
-is compiled with a \*(C+ compiler or your C and \*(C+ environments allow
-throwing exceptions through C libraries (most do).
-.SS "\*(C+ \s-1API\s0"
-.IX Subsection " API"
-Libev comes with some simplistic wrapper classes for \*(C+ that mainly allow
-you to use some convenience methods to start/stop watchers and also change
-the callback model to a model using method callbacks on objects.
-.PP
-To use it,
-.PP
-.Vb 1
-\& #include <ev++.h>
-.Ve
-.PP
-This automatically includes \fIev.h\fR and puts all of its definitions (many
-of them macros) into the global namespace. All \*(C+ specific things are
-put into the \f(CW\*(C`ev\*(C'\fR namespace. It should support all the same embedding
-options as \fIev.h\fR, most notably \f(CW\*(C`EV_MULTIPLICITY\*(C'\fR.
-.PP
-Care has been taken to keep the overhead low. The only data member the \*(C+
-classes add (compared to plain C\-style watchers) is the event loop pointer
-that the watcher is associated with (or no additional members at all if
-you disable \f(CW\*(C`EV_MULTIPLICITY\*(C'\fR when embedding libev).
-.PP
-Currently, functions, static and non-static member functions and classes
-with \f(CW\*(C`operator ()\*(C'\fR can be used as callbacks. Other types should be easy
-to add as long as they only need one additional pointer for context. If
-you need support for other types of functors please contact the author
-(preferably after implementing it).
-.PP
-For all this to work, your \*(C+ compiler either has to use the same calling
-conventions as your C compiler (for static member functions), or you have
-to embed libev and compile libev itself as \*(C+.
-.PP

-The constructor (optionally) takes an event loop to associate the watcher
-with. If it is omitted, it will use \f(CW\*(C`EV_DEFAULT\*(C'\fR.
-.Sp
-The constructor calls \f(CW\*(C`ev_init\*(C'\fR for you, which means you have to call the
-\&\f(CW\*(C`set\*(C'\fR method before starting it.
-.Sp
-It will not set a callback, however: You have to call the templated \f(CW\*(C`set\*(C'\fR
-method to set a callback before you can start the watcher.
-.Sp
-(The reason why you have to use a method is a limitation in \*(C+ which does
-not allow explicit template arguments for constructors).
-.Sp
-The destructor automatically stops the watcher if it is active.
-.IP "w\->set<class, &class::method> (object *)" 4
-.IX Item "w->set<class, &class::method> (object *)"
-This method sets the callback method to call. The method has to have a
-signature of \f(CW\*(C`void (*)(ev_TYPE &, int)\*(C'\fR, it receives the watcher as
-first argument and the \f(CW\*(C`revents\*(C'\fR as second. The object must be given as
-parameter and is stored in the \f(CW\*(C`data\*(C'\fR member of the watcher.
-.Sp
-This method synthesizes efficient thunking code to call your method from
-the C callback that libev requires. If your compiler can inline your
-callback (i.e. it is visible to it at the place of the \f(CW\*(C`set\*(C'\fR call and
-your compiler is good :), then the method will be fully inlined into the
-thunking function, making it as fast as a direct C callback.

-This is a variation of a method callback \- leaving out the method to call

-All libev functions are reentrant and thread-safe unless explicitly

-are no concurrent calls into any libev function with the same loop
-parameter (\f(CW\*(C`ev_default_*\*(C'\fR calls have an implicit default loop parameter,
-of course): libev guarantees that different event loops share no data

-.PP
-Or to put it differently: calls with different loop parameters can be done
-concurrently from multiple threads, calls with the same loop parameter
-must be done serially (but can be done from different threads, as long as
-only one thread ever is inside a call at any point in time, e.g. by using
-a mutex per loop).
-.PP
-Specifically to support threads (and signal handlers), libev implements
-so-called \f(CW\*(C`ev_async\*(C'\fR watchers, which allow some limited form of
-concurrency on the same event loop, namely waking it up \*(L"from the

-.PP
-If you want to know which design (one loop, locking, or multiple loops

-.IP "\(bu" 4
-most applications have a main thread: use the default libev loop
-in that thread, or create a separate thread running only the default loop.
-.Sp
-This helps integrating other libraries or software modules that use libev
-themselves and don't care/know about threading.
-.IP "\(bu" 4
-one loop per thread is usually a good model.
-.Sp
-Doing this is almost never wrong, sometimes a better-performance model
-exists, but it is always a good start.
-.IP "\(bu" 4
-other models exist, such as the leader/follower pattern, where one

-.Sp
-Choosing a model is hard \- look around, learn, know that usually you can do
-better than you currently do :\-)
-.IP "\(bu" 4
-often you need to talk to some other thread which blocks in the
-event loop.
-.Sp
-\&\f(CW\*(C`ev_async\*(C'\fR watchers can be used to wake them up from other threads safely
-(or from signal contexts...).
-.Sp
-An example use would be to communicate signals or other events that only
-work in the default loop by registering the signal watcher with the
-default loop and triggering an \f(CW\*(C`ev_async\*(C'\fR watcher from the default loop
-watcher callback into the event loop interested in the signal.

-Depending on your compiler and compiler settings, you might get no or a

-.PP
-However, these are unavoidable for many reasons. For one, each compiler
-has different warnings, and each user has different tastes regarding

-targeting a specific compiler and compiler-version.
-.PP
-Another reason is that some compiler warnings require elaborate
-workarounds, or other changes to the code that make it less clear and less
-maintainable.
-.PP
-And of course, some compiler warnings are just plain stupid, or simply
-wrong (because they don't actually warn about the condition their message

-Win32 doesn't support any of the standards (e.g. \s-1POSIX\s0) that libev

-model. Libev still offers limited functionality on this platform in
-the form of the \f(CW\*(C`EVBACKEND_SELECT\*(C'\fR backend, and only supports socket
-descriptors. This only applies when using Win32 natively, not when using
-e.g. cygwin. Actually, it only applies to the microsofts own compilers,
-as every compiler comes with a slightly differently broken/incompatible
-environment.
-.PP
-Lifting these limitations would basically require the full
-re-implementation of the I/O system. If you are into this kind of thing,
-then note that glib does exactly that for you in a very portable way (note
-also that glib is the slowest event library known to man).
-.PP
-There is no supported compilation method available on windows except
-embedding it into other applications.
-.PP
-Sensible signal handling is officially unsupported by Microsoft \- libev
-tries its best, but under most conditions, signals will simply not work.
-.PP
-Not a libev limitation but worth mentioning: windows apparently doesn't
-accept large writes: instead of resulting in a partial write, windows will
-either accept everything or return \f(CW\*(C`ENOBUFS\*(C'\fR if the buffer is too large,
-so make sure you only write small amounts into your sockets (less than a
-megabyte seems safe, but this apparently depends on the amount of memory
-available).
-.PP
-Due to the many, low, and arbitrary limits on the win32 platform and
-the abysmal performance of winsockets, using a large number of sockets
-is not recommended (and not reasonable). If your program needs to use
-more than a hundred or so sockets, then likely it needs to use a totally
-different implementation for windows, as libev offers the \s-1POSIX\s0 readiness
-notification model, which cannot be implemented efficiently on windows
-(due to Microsoft monopoly games).

-Newer versions support more handles, but you need to define \f(CW\*(C`FD_SETSIZE\*(C'\fR
-to some high number (e.g. \f(CW2048\fR) before compiling the winsocket select
-call (which might be in libev or elsewhere, for example, perl and many
-other interpreters do their own select emulation on windows).
-.PP
-Another limit is the number of file descriptors in the Microsoft runtime
-libraries, which by default is \f(CW64\fR (there must be a hidden \fI64\fR
-fetish or something like this inside Microsoft). You can increase this
-by calling \f(CW\*(C`_setmaxstdio\*(C'\fR, which can increase this limit to \f(CW2048\fR
-(another arbitrary limit), but is broken in many versions of the Microsoft
-runtime libraries. This might get you to about \f(CW512\fR or \f(CW2048\fR sockets
-(depending on windows version and/or the phase of the moon). To get more,

-=head1 ABOUT THIS DOCUMENT
-
-This document documents the libev software package.
-
-The newest version of this document is also available as an html-formatted
-web page you might find easier to navigate when reading it for the first
-time: L<http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod>.
-
-While this document tries to be as complete as possible in documenting
-libev, its usage and the rationale behind its design, it is not a tutorial
-on event-based programming, nor will it introduce event-based programming
-with libev.
-
-Familiarity with event based programming techniques in general is assumed
-throughout this document.
-
-=head1 WHAT TO READ WHEN IN A HURRY
-
-This manual tries to be very detailed, but unfortunately, this also makes
-it very long. If you just want to know the basics of libev, I suggest
-reading L</ANATOMY OF A WATCHER>, then the L</EXAMPLE PROGRAM> above and
-look up the missing functions in L</GLOBAL FUNCTIONS> and the C<ev_io> and
-C<ev_timer> sections in L</WATCHER TYPES>.
-
-=head1 ABOUT LIBEV
-
-Libev is an event loop: you register interest in certain events (such as a
-file descriptor being readable or a timeout occurring), and it will manage
-these event sources and provide your program with events.
-
-To do this, it must take more or less complete control over your process
-(or thread) by executing the I<event loop> handler, and will then
-communicate events via a callback mechanism.
-
-You register interest in certain events by registering so-called I<event
-watchers>, which are relatively small C structures you initialise with the
-details of the event, and then hand it over to libev by I<starting> the
-watcher.
-
-=head2 FEATURES
-
-Libev supports C<select>, C<poll>, the Linux-specific C<epoll>, the
-BSD-specific C<kqueue> and the Solaris-specific event port mechanisms
-for file descriptor events (C<ev_io>), the Linux C<inotify> interface
-(for C<ev_stat>), Linux eventfd/signalfd (for faster and cleaner
-inter-thread wakeup (C<ev_async>)/signal handling (C<ev_signal>)) relative
-timers (C<ev_timer>), absolute timers with customised rescheduling
-(C<ev_periodic>), synchronous signals (C<ev_signal>), process status
-change events (C<ev_child>), and event watchers dealing with the event
-loop mechanism itself (C<ev_idle>, C<ev_embed>, C<ev_prepare> and
-C<ev_check> watchers) as well as file watchers (C<ev_stat>) and even
-limited support for fork events (C<ev_fork>).
-
-It also is quite fast (see this
-L<benchmark|http://libev.schmorp.de/bench.html> comparing it to libevent
-for example).
-
-=head2 CONVENTIONS
-
-Libev is very configurable. In this manual the default (and most common)
-configuration will be described, which supports multiple event loops. For
-more info about various configuration options please have a look at
-B<EMBED> section in this manual. If libev was configured without support
-for multiple event loops, then all functions taking an initial argument of
-name C<loop> (which is always of type C<struct ev_loop *>) will not have
-this argument.
-
-=head2 TIME REPRESENTATION
-
-Libev represents time as a single floating point number, representing
-the (fractional) number of seconds since the (POSIX) epoch (in practice
-somewhere near the beginning of 1970, details are complicated, don't
-ask). This type is called C<ev_tstamp>, which is what you should use
-too. It usually aliases to the C<double> type in C. When you need to do
-any calculations on it, you should treat it as some floating point value.
-
-Unlike the name component C<stamp> might indicate, it is also used for
-time differences (e.g. delays) throughout libev.
-
-=head1 ERROR HANDLING
-
-Libev knows three classes of errors: operating system errors, usage errors
-and internal errors (bugs).
-
-When libev catches an operating system error it cannot handle (for example
-a system call indicating a condition libev cannot fix), it calls the callback
-set via C<ev_set_syserr_cb>, which is supposed to fix the problem or
-abort. The default is to print a diagnostic message and to call C<abort
-()>.
-
-When libev detects a usage error such as a negative timer interval, then
-it will print a diagnostic message and abort (via the C<assert> mechanism,
-so C<NDEBUG> will disable this checking): these are programming errors in
-the libev caller and need to be fixed there.
-
-Libev also has a few internal error-checking C<assert>ions, and also has
-extensive consistency checking code. These do not trigger under normal
-circumstances, as they indicate either a bug in libev or worse.
-
-
-=head1 GLOBAL FUNCTIONS
-
-These functions can be called anytime, even before initialising the
-library in any way.
-
-=over 4
-
-=item ev_tstamp ev_time ()
-
-Returns the current time as libev would use it. Please note that the
-C<ev_now> function is usually faster and also often returns the timestamp
-you actually want to know. Also interesting is the combination of
-C<ev_now_update> and C<ev_now>.
-
-=item ev_sleep (ev_tstamp interval)
-
-Sleep for the given interval: The current thread will be blocked
-until either it is interrupted or the given time interval has
-passed (approximately - it might return a bit earlier even if not
-interrupted). Returns immediately if C<< interval <= 0 >>.
-
-Basically this is a sub-second-resolution C<sleep ()>.
-
-The range of the C<interval> is limited - libev only guarantees to work
-with sleep times of up to one day (C<< interval <= 86400 >>).
-
-=item int ev_version_major ()
-
-=item int ev_version_minor ()
-
-You can find out the major and minor ABI version numbers of the library
-you linked against by calling the functions C<ev_version_major> and
-C<ev_version_minor>. If you want, you can compare against the global
-symbols C<EV_VERSION_MAJOR> and C<EV_VERSION_MINOR>, which specify the
-version of the library your program was compiled against.
-
-These version numbers refer to the ABI version of the library, not the
-release version.
-
-Usually, it's a good idea to terminate if the major versions mismatch,
-as this indicates an incompatible change. Minor versions are usually
-compatible to older versions, so a larger minor version alone is usually
-not a problem.
-
-Example: Make sure we haven't accidentally been linked against the wrong
-version (note, however, that this will not detect other ABI mismatches,
-such as LFS or reentrancy).
-
- assert (("libev version mismatch",
- ev_version_major () == EV_VERSION_MAJOR
- && ev_version_minor () >= EV_VERSION_MINOR));
-
-=item unsigned int ev_supported_backends ()
-
-Return the set of all backends (i.e. their corresponding C<EV_BACKEND_*>
-value) compiled into this binary of libev (independent of their
-availability on the system you are running on). See C<ev_default_loop> for
-a description of the set values.
-
-Example: make sure we have the epoll method, because yeah this is cool and
-a must have and can we have a torrent of it please!!!11
-
- assert (("sorry, no epoll, no sex",
- ev_supported_backends () & EVBACKEND_EPOLL));
-
-=item unsigned int ev_recommended_backends ()
-
-Return the set of all backends compiled into this binary of libev and
-also recommended for this platform, meaning it will work for most file
-descriptor types. This set is often smaller than the one returned by
-C<ev_supported_backends>, as for example kqueue is broken on most BSDs
-and will not be auto-detected unless you explicitly request it (assuming
-you know what you are doing). This is the set of backends that libev will
-probe for if you specify no backends explicitly.
-
-=item unsigned int ev_embeddable_backends ()
-
-Returns the set of backends that are embeddable in other event loops. This
-value is platform-specific but can include backends not available on the
-current system. To find which embeddable backends might be supported on
-the current system, you would need to look at C<ev_embeddable_backends ()
-& ev_supported_backends ()>, likewise for recommended ones.
-
-See the description of C<ev_embed> watchers for more info.
-
-=item ev_set_allocator (void *(*cb)(void *ptr, long size) throw ())
-
-Sets the allocation function to use (the prototype is similar - the
-semantics are identical to the C<realloc> C89/SuS/POSIX function). It is
-used to allocate and free memory (no surprises here). If it returns zero
-when memory needs to be allocated (C<size != 0>), the library might abort
-or take some potentially destructive action.
-
-Since some systems (at least OpenBSD and Darwin) fail to implement
-correct C<realloc> semantics, libev will use a wrapper around the system
-C<realloc> and C<free> functions by default.
-
-You could override this function in high-availability programs to, say,
-free some memory if it cannot allocate memory, to use a special allocator,
-or even to sleep a while and retry until some memory is available.
-
-Example: Replace the libev allocator with one that waits a bit and then
-retries (example requires a standards-compliant C<realloc>).
-
- static void *
- persistent_realloc (void *ptr, size_t size)
- {
- for (;;)
- {
- void *newptr = realloc (ptr, size);
-
- if (newptr)
- return newptr;
-
- sleep (60);
- }
- }
-
- ...
- ev_set_allocator (persistent_realloc);
-
-=item ev_set_syserr_cb (void (*cb)(const char *msg) throw ())
-
-Set the callback function to call on a retryable system call error (such
-as failed select, poll, epoll_wait). The message is a printable string
-indicating the system call or subsystem causing the problem. If this
-callback is set, then libev will expect it to remedy the situation, no
-matter what, when it returns. That is, libev will generally retry the
-requested operation, or, if the condition doesn't go away, do bad stuff
-(such as abort).
-
-Example: This is basically the same thing that libev does internally, too.
-
- static void
- fatal_error (const char *msg)
- {
- perror (msg);
- abort ();
- }
-
- ...
- ev_set_syserr_cb (fatal_error);
-
-=item ev_feed_signal (int signum)
-
-This function can be used to "simulate" a signal receive. It is completely
-safe to call this function at any time, from any context, including signal
-handlers or random threads.
-
-Its main use is to customise signal handling in your process, especially
-in the presence of threads. For example, you could block signals
-by default in all threads (and specifying C<EVFLAG_NOSIGMASK> when
-creating any loops), and in one thread, use C<sigwait> or any other
-mechanism to wait for signals, then "deliver" them to libev by calling
-C<ev_feed_signal>.
-
-=back
-
-=head1 FUNCTIONS CONTROLLING EVENT LOOPS
-
-An event loop is described by a C<struct ev_loop *> (the C<struct> is
-I<not> optional in this case unless libev 3 compatibility is disabled, as
-libev 3 had an C<ev_loop> function colliding with the struct name).
-
-The library knows two types of such loops, the I<default> loop, which
-supports child process events, and dynamically created event loops which
-do not.
-
-=over 4
-
-=item struct ev_loop *ev_default_loop (unsigned int flags)
-
-This returns the "default" event loop object, which is what you should
-normally use when you just need "the event loop". Event loop objects and
-the C<flags> parameter are described in more detail in the entry for
-C<ev_loop_new>.
-
-If the default loop is already initialised then this function simply
-returns it (and ignores the flags. If that is troubling you, check
-C<ev_backend ()> afterwards). Otherwise it will create it with the given
-flags, which should almost always be C<0>, unless the caller is also the
-one calling C<ev_run> or otherwise qualifies as "the main program".
-
-If you don't know what event loop to use, use the one returned from this
-function (or via the C<EV_DEFAULT> macro).
-
-Note that this function is I<not> thread-safe, so if you want to use it
-from multiple threads, you have to employ some kind of mutex (note also
-that this case is unlikely, as loops cannot be shared easily between
-threads anyway).
-
-The default loop is the only loop that can handle C<ev_child> watchers,
-and to do this, it always registers a handler for C<SIGCHLD>. If this is
-a problem for your application you can either create a dynamic loop with
-C<ev_loop_new> which doesn't do that, or you can simply overwrite the
-C<SIGCHLD> signal handler I<after> calling C<ev_default_init>.
-
-Example: This is the most typical usage.
-
- if (!ev_default_loop (0))
- fatal ("could not initialise libev, bad $LIBEV_FLAGS in environment?");
-
-Example: Restrict libev to the select and poll backends, and do not allow
-environment settings to be taken into account:
-
- ev_default_loop (EVBACKEND_POLL | EVBACKEND_SELECT | EVFLAG_NOENV);
-
-=item struct ev_loop *ev_loop_new (unsigned int flags)
-
-This will create and initialise a new event loop object. If the loop
-could not be initialised, returns false.
-
-This function is thread-safe, and one common way to use libev with
-threads is indeed to create one loop per thread, and using the default
-loop in the "main" or "initial" thread.
-
-The flags argument can be used to specify special behaviour or specific
-backends to use, and is usually specified as C<0> (or C<EVFLAG_AUTO>).
-
-The following flags are supported:
-
-=over 4
-
-=item C<EVFLAG_AUTO>
-
-The default flags value. Use this if you have no clue (it's the right
-thing, believe me).
-
-=item C<EVFLAG_NOENV>
-
-If this flag bit is or'ed into the flag value (or the program runs setuid
-or setgid) then libev will I<not> look at the environment variable
-C<LIBEV_FLAGS>. Otherwise (the default), this environment variable will
-override the flags completely if it is found in the environment. This is
-useful to try out specific backends to test their performance, or to work
-around bugs.
-
-=item C<EVFLAG_FORKCHECK>
-
-Instead of calling C<ev_loop_fork> manually after a fork, you can also
-make libev check for a fork in each iteration by enabling this flag.
-
-This works by calling C<getpid ()> on every iteration of the loop,
-and thus this might slow down your event loop if you do a lot of loop
-iterations and little real work, but is usually not noticeable (on my
-GNU/Linux system for example, C<getpid> is actually a simple 5-insn sequence
-without a system call and thus I<very> fast, but my GNU/Linux system also has
-C<pthread_atfork> which is even faster).
-
-The big advantage of this flag is that you can forget about fork (and
-forget about forgetting to tell libev about forking) when you use this
-flag.
-
-This flag setting cannot be overridden or specified in the C<LIBEV_FLAGS>
-environment variable.
-
-=item C<EVFLAG_NOINOTIFY>
-
-When this flag is specified, then libev will not attempt to use the
-I<inotify> API for its C<ev_stat> watchers. Apart from debugging and
-testing, this flag can be useful to conserve inotify file descriptors, as
-otherwise each loop using C<ev_stat> watchers consumes one inotify handle.
-
-=item C<EVFLAG_SIGNALFD>
-
-When this flag is specified, then libev will attempt to use the
-I<signalfd> API for its C<ev_signal> (and C<ev_child>) watchers. This API
-delivers signals synchronously, which makes it both faster and might make
-it possible to get the queued signal data. It can also simplify signal
-handling with threads, as long as you properly block signals in your
-threads that are not interested in handling them.
-
-Signalfd will not be used by default as this changes your signal mask, and
-there are a lot of shoddy libraries and programs (glib's threadpool for
-example) that can't properly initialise their signal masks.
-
-=item C<EVFLAG_NOSIGMASK>
-
-When this flag is specified, then libev will avoid to modify the signal
-mask. Specifically, this means you have to make sure signals are unblocked
-when you want to receive them.
-
-This behaviour is useful when you want to do your own signal handling, or
-want to handle signals only in specific threads and want to avoid libev
-unblocking the signals.
-
-It's also required by POSIX in a threaded program, as libev calls
-C<sigprocmask>, whose behaviour is officially unspecified.
-
-This flag's behaviour will become the default in future versions of libev.
-
-=item C<EVBACKEND_SELECT> (value 1, portable select backend)
-
-This is your standard select(2) backend. Not I<completely> standard, as
-libev tries to roll its own fd_set with no limits on the number of fds,
-but if that fails, expect a fairly low limit on the number of fds when
-using this backend. It doesn't scale too well (O(highest_fd)), but its
-usually the fastest backend for a low number of (low-numbered :) fds.
-
-To get good performance out of this backend you need a high amount of
-parallelism (most of the file descriptors should be busy). If you are
-writing a server, you should C<accept ()> in a loop to accept as many
-connections as possible during one iteration. You might also want to have
-a look at C<ev_set_io_collect_interval ()> to increase the amount of
-readiness notifications you get per iteration.
-
-This backend maps C<EV_READ> to the C<readfds> set and C<EV_WRITE> to the
-C<writefds> set (and to work around Microsoft Windows bugs, also onto the
-C<exceptfds> set on that platform).
-
-=item C<EVBACKEND_POLL> (value 2, poll backend, available everywhere except on windows)
-
-And this is your standard poll(2) backend. It's more complicated
-than select, but handles sparse fds better and has no artificial
-limit on the number of fds you can use (except it will slow down
-considerably with a lot of inactive fds). It scales similarly to select,
-i.e. O(total_fds). See the entry for C<EVBACKEND_SELECT>, above, for
-performance tips.
-
-This backend maps C<EV_READ> to C<POLLIN | POLLERR | POLLHUP>, and
-C<EV_WRITE> to C<POLLOUT | POLLERR | POLLHUP>.
-
-=item C<EVBACKEND_EPOLL> (value 4, Linux)
-
-Use the linux-specific epoll(7) interface (for both pre- and post-2.6.9
-kernels).
-
-For few fds, this backend is a bit little slower than poll and select, but
-it scales phenomenally better. While poll and select usually scale like
-O(total_fds) where total_fds is the total number of fds (or the highest
-fd), epoll scales either O(1) or O(active_fds).
-
-The epoll mechanism deserves honorable mention as the most misdesigned
-of the more advanced event mechanisms: mere annoyances include silently
-dropping file descriptors, requiring a system call per change per file
-descriptor (and unnecessary guessing of parameters), problems with dup,
-returning before the timeout value, resulting in additional iterations
-(and only giving 5ms accuracy while select on the same platform gives
-0.1ms) and so on. The biggest issue is fork races, however - if a program
-forks then I<both> parent and child process have to recreate the epoll
-set, which can take considerable time (one syscall per file descriptor)
-and is of course hard to detect.
-
-Epoll is also notoriously buggy - embedding epoll fds I<should> work,
-but of course I<doesn't>, and epoll just loves to report events for
-totally I<different> file descriptors (even already closed ones, so
-one cannot even remove them from the set) than registered in the set
-(especially on SMP systems). Libev tries to counter these spurious
-notifications by employing an additional generation counter and comparing
-that against the events to filter out spurious ones, recreating the set
-when required. Epoll also erroneously rounds down timeouts, but gives you
-no way to know when and by how much, so sometimes you have to busy-wait
-because epoll returns immediately despite a nonzero timeout. And last
-not least, it also refuses to work with some file descriptors which work
-perfectly fine with C<select> (files, many character devices...).
-
-Epoll is truly the train wreck among event poll mechanisms, a frankenpoll,
-cobbled together in a hurry, no thought to design or interaction with
-others. Oh, the pain, will it ever stop...
-
-While stopping, setting and starting an I/O watcher in the same iteration
-will result in some caching, there is still a system call per such
-incident (because the same I<file descriptor> could point to a different
-I<file description> now), so its best to avoid that. Also, C<dup ()>'ed
-file descriptors might not work very well if you register events for both
-file descriptors.
-
-Best performance from this backend is achieved by not unregistering all
-watchers for a file descriptor until it has been closed, if possible,
-i.e. keep at least one watcher active per fd at all times. Stopping and
-starting a watcher (without re-setting it) also usually doesn't cause
-extra overhead. A fork can both result in spurious notifications as well
-as in libev having to destroy and recreate the epoll object, which can
-take considerable time and thus should be avoided.
-
-All this means that, in practice, C<EVBACKEND_SELECT> can be as fast or
-faster than epoll for maybe up to a hundred file descriptors, depending on
-the usage. So sad.
-
-While nominally embeddable in other event loops, this feature is broken in
-all kernel versions tested so far.
-
-This backend maps C<EV_READ> and C<EV_WRITE> in the same way as
-C<EVBACKEND_POLL>.
-
-=item C<EVBACKEND_KQUEUE> (value 8, most BSD clones)
-
-Kqueue deserves special mention, as at the time of this writing, it
-was broken on all BSDs except NetBSD (usually it doesn't work reliably
-with anything but sockets and pipes, except on Darwin, where of course
-it's completely useless). Unlike epoll, however, whose brokenness
-is by design, these kqueue bugs can (and eventually will) be fixed
-without API changes to existing programs. For this reason it's not being
-"auto-detected" unless you explicitly specify it in the flags (i.e. using
-C<EVBACKEND_KQUEUE>) or libev was compiled on a known-to-be-good (-enough)
-system like NetBSD.
-
-You still can embed kqueue into a normal poll or select backend and use it
-only for sockets (after having made sure that sockets work with kqueue on
-the target platform). See C<ev_embed> watchers for more info.
-
-It scales in the same way as the epoll backend, but the interface to the
-kernel is more efficient (which says nothing about its actual speed, of
-course). While stopping, setting and starting an I/O watcher does never
-cause an extra system call as with C<EVBACKEND_EPOLL>, it still adds up to
-two event changes per incident. Support for C<fork ()> is very bad (you
-might have to leak fd's on fork, but it's more sane than epoll) and it
-drops fds silently in similarly hard-to-detect cases.
-
-This backend usually performs well under most conditions.
-
-While nominally embeddable in other event loops, this doesn't work
-everywhere, so you might need to test for this. And since it is broken
-almost everywhere, you should only use it when you have a lot of sockets
-(for which it usually works), by embedding it into another event loop
-(e.g. C<EVBACKEND_SELECT> or C<EVBACKEND_POLL> (but C<poll> is of course
-also broken on OS X)) and, did I mention it, using it only for sockets.
-
-This backend maps C<EV_READ> into an C<EVFILT_READ> kevent with
-C<NOTE_EOF>, and C<EV_WRITE> into an C<EVFILT_WRITE> kevent with
-C<NOTE_EOF>.
-
-=item C<EVBACKEND_DEVPOLL> (value 16, Solaris 8)
-
-This is not implemented yet (and might never be, unless you send me an
-implementation). According to reports, C</dev/poll> only supports sockets
-and is not embeddable, which would limit the usefulness of this backend
-immensely.
-
-=item C<EVBACKEND_PORT> (value 32, Solaris 10)
-
-This uses the Solaris 10 event port mechanism. As with everything on Solaris,
-it's really slow, but it still scales very well (O(active_fds)).
-
-While this backend scales well, it requires one system call per active
-file descriptor per loop iteration. For small and medium numbers of file
-descriptors a "slow" C<EVBACKEND_SELECT> or C<EVBACKEND_POLL> backend
-might perform better.
-
-On the positive side, this backend actually performed fully to
-specification in all tests and is fully embeddable, which is a rare feat
-among the OS-specific backends (I vastly prefer correctness over speed
-hacks).
-
-On the negative side, the interface is I<bizarre> - so bizarre that
-even sun itself gets it wrong in their code examples: The event polling
-function sometimes returns events to the caller even though an error
-occurred, but with no indication whether it has done so or not (yes, it's
-even documented that way) - deadly for edge-triggered interfaces where you
-absolutely have to know whether an event occurred or not because you have
-to re-arm the watcher.
-
-Fortunately libev seems to be able to work around these idiocies.
-
-This backend maps C<EV_READ> and C<EV_WRITE> in the same way as
-C<EVBACKEND_POLL>.
-
-=item C<EVBACKEND_ALL>
-
-Try all backends (even potentially broken ones that wouldn't be tried
-with C<EVFLAG_AUTO>). Since this is a mask, you can do stuff such as
-C<EVBACKEND_ALL & ~EVBACKEND_KQUEUE>.
-
-It is definitely not recommended to use this flag, use whatever
-C<ev_recommended_backends ()> returns, or simply do not specify a backend
-at all.
-
-=item C<EVBACKEND_MASK>
-
-Not a backend at all, but a mask to select all backend bits from a
-C<flags> value, in case you want to mask out any backends from a flags
-value (e.g. when modifying the C<LIBEV_FLAGS> environment variable).
-
-=back
-
-If one or more of the backend flags are or'ed into the flags value,
-then only these backends will be tried (in the reverse order as listed
-here). If none are specified, all backends in C<ev_recommended_backends
-()> will be tried.
-
-Example: Try to create a event loop that uses epoll and nothing else.
-
- struct ev_loop *epoller = ev_loop_new (EVBACKEND_EPOLL | EVFLAG_NOENV);
- if (!epoller)
- fatal ("no epoll found here, maybe it hides under your chair");
-
-Example: Use whatever libev has to offer, but make sure that kqueue is
-used if available.
-
- struct ev_loop *loop = ev_loop_new (ev_recommended_backends () | EVBACKEND_KQUEUE);
-
-=item ev_loop_destroy (loop)
-
-Destroys an event loop object (frees all memory and kernel state
-etc.). None of the active event watchers will be stopped in the normal
-sense, so e.g. C<ev_is_active> might still return true. It is your
-responsibility to either stop all watchers cleanly yourself I<before>
-calling this function, or cope with the fact afterwards (which is usually
-the easiest thing, you can just ignore the watchers and/or C<free ()> them
-for example).
-
-Note that certain global state, such as signal state (and installed signal
-handlers), will not be freed by this function, and related watchers (such
-as signal and child watchers) would need to be stopped manually.
-
-This function is normally used on loop objects allocated by
-C<ev_loop_new>, but it can also be used on the default loop returned by
-C<ev_default_loop>, in which case it is not thread-safe.
-
-Note that it is not advisable to call this function on the default loop
-except in the rare occasion where you really need to free its resources.
-If you need dynamically allocated loops it is better to use C<ev_loop_new>
-and C<ev_loop_destroy>.
-
-=item ev_loop_fork (loop)
-
-This function sets a flag that causes subsequent C<ev_run> iterations to
-reinitialise the kernel state for backends that have one. Despite the
-name, you can call it anytime, but it makes most sense after forking, in
-the child process. You I<must> call it (or use C<EVFLAG_FORKCHECK>) in the
-child before resuming or calling C<ev_run>.
-
-Again, you I<have> to call it on I<any> loop that you want to re-use after
-a fork, I<even if you do not plan to use the loop in the parent>. This is
-because some kernel interfaces *cough* I<kqueue> *cough* do funny things
-during fork.
-
-On the other hand, you only need to call this function in the child
-process if and only if you want to use the event loop in the child. If
-you just fork+exec or create a new loop in the child, you don't have to
-call it at all (in fact, C<epoll> is so badly broken that it makes a
-difference, but libev will usually detect this case on its own and do a
-costly reset of the backend).
-
-The function itself is quite fast and it's usually not a problem to call
-it just in case after a fork.
-
-Example: Automate calling C<ev_loop_fork> on the default loop when
-using pthreads.
-
- static void
- post_fork_child (void)
- {
- ev_loop_fork (EV_DEFAULT);
- }
-
- ...
- pthread_atfork (0, 0, post_fork_child);
-
-=item int ev_is_default_loop (loop)
-
-Returns true when the given loop is, in fact, the default loop, and false
-otherwise.
-
-=item unsigned int ev_iteration (loop)
-
-Returns the current iteration count for the event loop, which is identical
-to the number of times libev did poll for new events. It starts at C<0>
-and happily wraps around with enough iterations.
-
-This value can sometimes be useful as a generation counter of sorts (it
-"ticks" the number of loop iterations), as it roughly corresponds with
-C<ev_prepare> and C<ev_check> calls - and is incremented between the
-prepare and check phases.
-
-=item unsigned int ev_depth (loop)
-
-Returns the number of times C<ev_run> was entered minus the number of
-times C<ev_run> was exited normally, in other words, the recursion depth.
-
-Outside C<ev_run>, this number is zero. In a callback, this number is
-C<1>, unless C<ev_run> was invoked recursively (or from another thread),
-in which case it is higher.
-
-Leaving C<ev_run> abnormally (setjmp/longjmp, cancelling the thread,
-throwing an exception etc.), doesn't count as "exit" - consider this
-as a hint to avoid such ungentleman-like behaviour unless it's really
-convenient, in which case it is fully supported.
-
-=item unsigned int ev_backend (loop)
-
-Returns one of the C<EVBACKEND_*> flags indicating the event backend in
-use.
-
-=item ev_tstamp ev_now (loop)
-
-Returns the current "event loop time", which is the time the event loop
-received events and started processing them. This timestamp does not
-change as long as callbacks are being processed, and this is also the base
-time used for relative timers. You can treat it as the timestamp of the
-event occurring (or more correctly, libev finding out about it).
-
-=item ev_now_update (loop)
-
-Establishes the current time by querying the kernel, updating the time
-returned by C<ev_now ()> in the progress. This is a costly operation and
-is usually done automatically within C<ev_run ()>.
-
-This function is rarely useful, but when some event callback runs for a
-very long time without entering the event loop, updating libev's idea of
-the current time is a good idea.
-
-See also L</The special problem of time updates> in the C<ev_timer> section.
-
-=item ev_suspend (loop)
-
-=item ev_resume (loop)
-
-These two functions suspend and resume an event loop, for use when the
-loop is not used for a while and timeouts should not be processed.
-
-A typical use case would be an interactive program such as a game: When
-the user presses C<^Z> to suspend the game and resumes it an hour later it
-would be best to handle timeouts as if no time had actually passed while
-the program was suspended. This can be achieved by calling C<ev_suspend>
-in your C<SIGTSTP> handler, sending yourself a C<SIGSTOP> and calling
-C<ev_resume> directly afterwards to resume timer processing.
-
-Effectively, all C<ev_timer> watchers will be delayed by the time spend
-between C<ev_suspend> and C<ev_resume>, and all C<ev_periodic> watchers
-will be rescheduled (that is, they will lose any events that would have
-occurred while suspended).
-
-After calling C<ev_suspend> you B<must not> call I<any> function on the
-given loop other than C<ev_resume>, and you B<must not> call C<ev_resume>
-without a previous call to C<ev_suspend>.
-
-Calling C<ev_suspend>/C<ev_resume> has the side effect of updating the
-event loop time (see C<ev_now_update>).
-
-=item bool ev_run (loop, int flags)
-
-Finally, this is it, the event handler. This function usually is called
-after you have initialised all your watchers and you want to start
-handling events. It will ask the operating system for any new events, call
-the watcher callbacks, and then repeat the whole process indefinitely: This
-is why event loops are called I<loops>.
-
-If the flags argument is specified as C<0>, it will keep handling events
-until either no event watchers are active anymore or C<ev_break> was
-called.
-
-The return value is false if there are no more active watchers (which
-usually means "all jobs done" or "deadlock"), and true in all other cases
-(which usually means " you should call C<ev_run> again").
-
-Please note that an explicit C<ev_break> is usually better than
-relying on all watchers to be stopped when deciding when a program has
-finished (especially in interactive programs), but having a program
-that automatically loops as long as it has to and no longer by virtue
-of relying on its watchers stopping correctly, that is truly a thing of
-beauty.
-
-This function is I<mostly> exception-safe - you can break out of a
-C<ev_run> call by calling C<longjmp> in a callback, throwing a C++
-exception and so on. This does not decrement the C<ev_depth> value, nor
-will it clear any outstanding C<EVBREAK_ONE> breaks.
-
-A flags value of C<EVRUN_NOWAIT> will look for new events, will handle
-those events and any already outstanding ones, but will not wait and
-block your process in case there are no events and will return after one
-iteration of the loop. This is sometimes useful to poll and handle new
-events while doing lengthy calculations, to keep the program responsive.
-
-A flags value of C<EVRUN_ONCE> will look for new events (waiting if
-necessary) and will handle those and any already outstanding ones. It
-will block your process until at least one new event arrives (which could
-be an event internal to libev itself, so there is no guarantee that a
-user-registered callback will be called), and will return after one
-iteration of the loop.
-
-This is useful if you are waiting for some external event in conjunction
-with something not expressible using other libev watchers (i.e. "roll your
-own C<ev_run>"). However, a pair of C<ev_prepare>/C<ev_check> watchers is
-usually a better approach for this kind of thing.
-
-Here are the gory details of what C<ev_run> does (this is for your
-understanding, not a guarantee that things will work exactly like this in
-future versions):
-
- - Increment loop depth.
- - Reset the ev_break status.
- - Before the first iteration, call any pending watchers.
- LOOP:
- - If EVFLAG_FORKCHECK was used, check for a fork.
- - If a fork was detected (by any means), queue and call all fork watchers.
- - Queue and call all prepare watchers.
- - If ev_break was called, goto FINISH.
- - If we have been forked, detach and recreate the kernel state
- as to not disturb the other process.
- - Update the kernel state with all outstanding changes.
- - Update the "event loop time" (ev_now ()).
- - Calculate for how long to sleep or block, if at all
- (active idle watchers, EVRUN_NOWAIT or not having
- any active watchers at all will result in not sleeping).
- - Sleep if the I/O and timer collect interval say so.
- - Increment loop iteration counter.
- - Block the process, waiting for any events.
- - Queue all outstanding I/O (fd) events.
- - Update the "event loop time" (ev_now ()), and do time jump adjustments.
- - Queue all expired timers.
- - Queue all expired periodics.
- - Queue all idle watchers with priority higher than that of pending events.
- - Queue all check watchers.
- - Call all queued watchers in reverse order (i.e. check watchers first).
- Signals and child watchers are implemented as I/O watchers, and will
- be handled here by queueing them when their watcher gets executed.
- - If ev_break has been called, or EVRUN_ONCE or EVRUN_NOWAIT
- were used, or there are no active watchers, goto FINISH, otherwise
- continue with step LOOP.
- FINISH:
- - Reset the ev_break status iff it was EVBREAK_ONE.
- - Decrement the loop depth.
- - Return.
-
-Example: Queue some jobs and then loop until no events are outstanding
-anymore.
-
- ... queue jobs here, make sure they register event watchers as long
- ... as they still have work to do (even an idle watcher will do..)
- ev_run (my_loop, 0);
- ... jobs done or somebody called break. yeah!
-
-=item ev_break (loop, how)
-
-Can be used to make a call to C<ev_run> return early (but only after it
-has processed all outstanding events). The C<how> argument must be either
-C<EVBREAK_ONE>, which will make the innermost C<ev_run> call return, or
-C<EVBREAK_ALL>, which will make all nested C<ev_run> calls return.
-
-This "break state" will be cleared on the next call to C<ev_run>.
-
-It is safe to call C<ev_break> from outside any C<ev_run> calls, too, in
-which case it will have no effect.
-
-=item ev_ref (loop)
-
-=item ev_unref (loop)
-
-Ref/unref can be used to add or remove a reference count on the event
-loop: Every watcher keeps one reference, and as long as the reference
-count is nonzero, C<ev_run> will not return on its own.
-
-This is useful when you have a watcher that you never intend to
-unregister, but that nevertheless should not keep C<ev_run> from
-returning. In such a case, call C<ev_unref> after starting, and C<ev_ref>
-before stopping it.
-
-As an example, libev itself uses this for its internal signal pipe: It
-is not visible to the libev user and should not keep C<ev_run> from
-exiting if no event watchers registered by it are active. It is also an
-excellent way to do this for generic recurring timers or from within
-third-party libraries. Just remember to I<unref after start> and I<ref
-before stop> (but only if the watcher wasn't active before, or was active
-before, respectively. Note also that libev might stop watchers itself
-(e.g. non-repeating timers) in which case you have to C<ev_ref>
-in the callback).
-
-Example: Create a signal watcher, but keep it from keeping C<ev_run>
-running when nothing else is active.
-
- ev_signal exitsig;
- ev_signal_init (&exitsig, sig_cb, SIGINT);
- ev_signal_start (loop, &exitsig);
- ev_unref (loop);
-
-Example: For some weird reason, unregister the above signal handler again.
-
- ev_ref (loop);
- ev_signal_stop (loop, &exitsig);
-
-=item ev_set_io_collect_interval (loop, ev_tstamp interval)
-
-=item ev_set_timeout_collect_interval (loop, ev_tstamp interval)
-
-These advanced functions influence the time that libev will spend waiting
-for events. Both time intervals are by default C<0>, meaning that libev
-will try to invoke timer/periodic callbacks and I/O callbacks with minimum
-latency.
-
-Setting these to a higher value (the C<interval> I<must> be >= C<0>)
-allows libev to delay invocation of I/O and timer/periodic callbacks
-to increase efficiency of loop iterations (or to increase power-saving
-opportunities).
-
-The idea is that sometimes your program runs just fast enough to handle
-one (or very few) event(s) per loop iteration. While this makes the
-program responsive, it also wastes a lot of CPU time to poll for new
-events, especially with backends like C<select ()> which have a high
-overhead for the actual polling but can deliver many events at once.
-
-By setting a higher I<io collect interval> you allow libev to spend more
-time collecting I/O events, so you can handle more events per iteration,
-at the cost of increasing latency. Timeouts (both C<ev_periodic> and
-C<ev_timer>) will not be affected. Setting this to a non-null value will
-introduce an additional C<ev_sleep ()> call into most loop iterations. The
-sleep time ensures that libev will not poll for I/O events more often then
-once per this interval, on average (as long as the host time resolution is
-good enough).
-
-Likewise, by setting a higher I<timeout collect interval> you allow libev
-to spend more time collecting timeouts, at the expense of increased
-latency/jitter/inexactness (the watcher callback will be called
-later). C<ev_io> watchers will not be affected. Setting this to a non-null
-value will not introduce any overhead in libev.
-
-Many (busy) programs can usually benefit by setting the I/O collect
-interval to a value near C<0.1> or so, which is often enough for
-interactive servers (of course not for games), likewise for timeouts. It
-usually doesn't make much sense to set it to a lower value than C<0.01>,
-as this approaches the timing granularity of most systems. Note that if
-you do transactions with the outside world and you can't increase the
-parallelity, then this setting will limit your transaction rate (if you
-need to poll once per transaction and the I/O collect interval is 0.01,
-then you can't do more than 100 transactions per second).
-
-Setting the I<timeout collect interval> can improve the opportunity for
-saving power, as the program will "bundle" timer callback invocations that
-are "near" in time together, by delaying some, thus reducing the number of
-times the process sleeps and wakes up again. Another useful technique to
-reduce iterations/wake-ups is to use C<ev_periodic> watchers and make sure
-they fire on, say, one-second boundaries only.
-
-Example: we only need 0.1s timeout granularity, and we wish not to poll
-more often than 100 times per second:
-
- ev_set_timeout_collect_interval (EV_DEFAULT_UC_ 0.1);
- ev_set_io_collect_interval (EV_DEFAULT_UC_ 0.01);
-
-=item ev_invoke_pending (loop)
-
-This call will simply invoke all pending watchers while resetting their
-pending state. Normally, C<ev_run> does this automatically when required,
-but when overriding the invoke callback this call comes handy. This
-function can be invoked from a watcher - this can be useful for example
-when you want to do some lengthy calculation and want to pass further
-event handling to another thread (you still have to make sure only one
-thread executes within C<ev_invoke_pending> or C<ev_run> of course).
-
-=item int ev_pending_count (loop)
-
-Returns the number of pending watchers - zero indicates that no watchers
-are pending.
-
-=item ev_set_invoke_pending_cb (loop, void (*invoke_pending_cb)(EV_P))
-
-This overrides the invoke pending functionality of the loop: Instead of
-invoking all pending watchers when there are any, C<ev_run> will call
-this callback instead. This is useful, for example, when you want to
-invoke the actual watchers inside another context (another thread etc.).
-
-If you want to reset the callback, use C<ev_invoke_pending> as new
-callback.
-
-=item ev_set_loop_release_cb (loop, void (*release)(EV_P) throw (), void (*acquire)(EV_P) throw ())
-
-Sometimes you want to share the same loop between multiple threads. This
-can be done relatively simply by putting mutex_lock/unlock calls around
-each call to a libev function.
-
-However, C<ev_run> can run an indefinite time, so it is not feasible
-to wait for it to return. One way around this is to wake up the event
-loop via C<ev_break> and C<ev_async_send>, another way is to set these
-I<release> and I<acquire> callbacks on the loop.
-
-When set, then C<release> will be called just before the thread is
-suspended waiting for new events, and C<acquire> is called just
-afterwards.
-
-Ideally, C<release> will just call your mutex_unlock function, and
-C<acquire> will just call the mutex_lock function again.
-
-While event loop modifications are allowed between invocations of
-C<release> and C<acquire> (that's their only purpose after all), no
-modifications done will affect the event loop, i.e. adding watchers will
-have no effect on the set of file descriptors being watched, or the time
-waited. Use an C<ev_async> watcher to wake up C<ev_run> when you want it
-to take note of any changes you made.
-
-In theory, threads executing C<ev_run> will be async-cancel safe between
-invocations of C<release> and C<acquire>.
-
-See also the locking example in the C<THREADS> section later in this
-document.
-
-=item ev_set_userdata (loop, void *data)
-
-=item void *ev_userdata (loop)
-
-Set and retrieve a single C<void *> associated with a loop. When
-C<ev_set_userdata> has never been called, then C<ev_userdata> returns
-C<0>.
-
-These two functions can be used to associate arbitrary data with a loop,
-and are intended solely for the C<invoke_pending_cb>, C<release> and
-C<acquire> callbacks described above, but of course can be (ab-)used for
-any other purpose as well.
-
-=item ev_verify (loop)
-
-This function only does something when C<EV_VERIFY> support has been
-compiled in, which is the default for non-minimal builds. It tries to go
-through all internal structures and checks them for validity. If anything
-is found to be inconsistent, it will print an error message to standard
-error and call C<abort ()>.
-
-This can be used to catch bugs inside libev itself: under normal
-circumstances, this function will never abort as of course libev keeps its
-data structures consistent.
-
-=back
-
-
-=head1 ANATOMY OF A WATCHER
-
-In the following description, uppercase C<TYPE> in names stands for the
-watcher type, e.g. C<ev_TYPE_start> can mean C<ev_timer_start> for timer
-watchers and C<ev_io_start> for I/O watchers.
-
-A watcher is an opaque structure that you allocate and register to record
-your interest in some event. To make a concrete example, imagine you want
-to wait for STDIN to become readable, you would create an C<ev_io> watcher
-for that:
-
- static void my_cb (struct ev_loop *loop, ev_io *w, int revents)
- {
- ev_io_stop (w);
- ev_break (loop, EVBREAK_ALL);
- }
-
- struct ev_loop *loop = ev_default_loop (0);
-
- ev_io stdin_watcher;
-
- ev_init (&stdin_watcher, my_cb);
- ev_io_set (&stdin_watcher, STDIN_FILENO, EV_READ);
- ev_io_start (loop, &stdin_watcher);
-
- ev_run (loop, 0);
-
-As you can see, you are responsible for allocating the memory for your
-watcher structures (and it is I<usually> a bad idea to do this on the
-stack).
-
-Each watcher has an associated watcher structure (called C<struct ev_TYPE>
-or simply C<ev_TYPE>, as typedefs are provided for all watcher structs).
-
-Each watcher structure must be initialised by a call to C<ev_init (watcher
-*, callback)>, which expects a callback to be provided. This callback is
-invoked each time the event occurs (or, in the case of I/O watchers, each
-time the event loop detects that the file descriptor given is readable
-and/or writable).
-
-Each watcher type further has its own C<< ev_TYPE_set (watcher *, ...) >>
-macro to configure it, with arguments specific to the watcher type. There
-is also a macro to combine initialisation and setting in one call: C<<
-ev_TYPE_init (watcher *, callback, ...) >>.
-
-To make the watcher actually watch out for events, you have to start it
-with a watcher-specific start function (C<< ev_TYPE_start (loop, watcher
-*) >>), and you can stop watching for events at any time by calling the
-corresponding stop function (C<< ev_TYPE_stop (loop, watcher *) >>.
-
-As long as your watcher is active (has been started but not stopped) you
-must not touch the values stored in it. Most specifically you must never
-reinitialise it or call its C<ev_TYPE_set> macro.
-
-Each and every callback receives the event loop pointer as first, the
-registered watcher structure as second, and a bitset of received events as
-third argument.
-
-The received events usually include a single bit per event type received
-(you can receive multiple events at the same time). The possible bit masks
-are:
-
-=over 4
-
-=item C<EV_READ>
-
-=item C<EV_WRITE>
-
-The file descriptor in the C<ev_io> watcher has become readable and/or
-writable.
-
-=item C<EV_TIMER>
-
-The C<ev_timer> watcher has timed out.
-
-=item C<EV_PERIODIC>
-
-The C<ev_periodic> watcher has timed out.
-
-=item C<EV_SIGNAL>
-
-The signal specified in the C<ev_signal> watcher has been received by a thread.
-
-=item C<EV_CHILD>
-
-The pid specified in the C<ev_child> watcher has received a status change.
-
-=item C<EV_STAT>
-
-The path specified in the C<ev_stat> watcher changed its attributes somehow.
-
-=item C<EV_IDLE>
-
-The C<ev_idle> watcher has determined that you have nothing better to do.
-
-=item C<EV_PREPARE>
-
-=item C<EV_CHECK>
-
-All C<ev_prepare> watchers are invoked just I<before> C<ev_run> starts to
-gather new events, and all C<ev_check> watchers are queued (not invoked)
-just after C<ev_run> has gathered them, but before it queues any callbacks
-for any received events. That means C<ev_prepare> watchers are the last
-watchers invoked before the event loop sleeps or polls for new events, and
-C<ev_check> watchers will be invoked before any other watchers of the same
-or lower priority within an event loop iteration.
-
-Callbacks of both watcher types can start and stop as many watchers as
-they want, and all of them will be taken into account (for example, a
-C<ev_prepare> watcher might start an idle watcher to keep C<ev_run> from
-blocking).
-
-=item C<EV_EMBED>
-
-The embedded event loop specified in the C<ev_embed> watcher needs attention.
-
-=item C<EV_FORK>
-
-The event loop has been resumed in the child process after fork (see
-C<ev_fork>).
-
-=item C<EV_CLEANUP>
-
-The event loop is about to be destroyed (see C<ev_cleanup>).
-
-=item C<EV_ASYNC>
-
-The given async watcher has been asynchronously notified (see C<ev_async>).
-
-=item C<EV_CUSTOM>
-
-Not ever sent (or otherwise used) by libev itself, but can be freely used
-by libev users to signal watchers (e.g. via C<ev_feed_event>).
-
-=item C<EV_ERROR>
-
-An unspecified error has occurred, the watcher has been stopped. This might
-happen because the watcher could not be properly started because libev
-ran out of memory, a file descriptor was found to be closed or any other
-problem. Libev considers these application bugs.
-
-You best act on it by reporting the problem and somehow coping with the
-watcher being stopped. Note that well-written programs should not receive
-an error ever, so when your watcher receives it, this usually indicates a
-bug in your program.
-
-Libev will usually signal a few "dummy" events together with an error, for
-example it might indicate that a fd is readable or writable, and if your
-callbacks is well-written it can just attempt the operation and cope with
-the error from read() or write(). This will not work in multi-threaded
-programs, though, as the fd could already be closed and reused for another
-thing, so beware.

-=head2 GENERIC WATCHER FUNCTIONS
-
-=over 4
-
-=item C<ev_init> (ev_TYPE *watcher, callback)
-
-This macro initialises the generic portion of a watcher. The contents
-of the watcher object can be arbitrary (so C<malloc> will do). Only
-the generic parts of the watcher are initialised, you I<need> to call
-the type-specific C<ev_TYPE_set> macro afterwards to initialise the
-type-specific parts. For each type there is also a C<ev_TYPE_init> macro
-which rolls both calls into one.
-
-You can reinitialise a watcher at any time as long as it has been stopped
-(or never started) and there are no pending events outstanding.
-
-The callback is always of type C<void (*)(struct ev_loop *loop, ev_TYPE *watcher,
-int revents)>.
-
-Example: Initialise an C<ev_io> watcher in two steps.
-
- ev_io w;
- ev_init (&w, my_cb);
- ev_io_set (&w, STDIN_FILENO, EV_READ);
-
-=item C<ev_TYPE_set> (ev_TYPE *watcher, [args])
-
-This macro initialises the type-specific parts of a watcher. You need to
-call C<ev_init> at least once before you call this macro, but you can
-call C<ev_TYPE_set> any number of times. You must not, however, call this
-macro on a watcher that is active (it can be pending, however, which is a
-difference to the C<ev_init> macro).
-
-Although some watcher types do not have type-specific arguments
-(e.g. C<ev_prepare>) you still need to call its C<set> macro.
-
-See C<ev_init>, above, for an example.
-
-=item C<ev_TYPE_init> (ev_TYPE *watcher, callback, [args])
-
-This convenience macro rolls both C<ev_init> and C<ev_TYPE_set> macro
-calls into a single call. This is the most convenient method to initialise
-a watcher. The same limitations apply, of course.
-
-Example: Initialise and set an C<ev_io> watcher in one step.
-
- ev_io_init (&w, my_cb, STDIN_FILENO, EV_READ);
-
-=item C<ev_TYPE_start> (loop, ev_TYPE *watcher)
-
-Starts (activates) the given watcher. Only active watchers will receive
-events. If the watcher is already active nothing will happen.
-
-Example: Start the C<ev_io> watcher that is being abused as example in this
-whole section.
-
- ev_io_start (EV_DEFAULT_UC, &w);
-
-=item C<ev_TYPE_stop> (loop, ev_TYPE *watcher)
-
-Stops the given watcher if active, and clears the pending status (whether
-the watcher was active or not).
-
-It is possible that stopped watchers are pending - for example,
-non-repeating timers are being stopped when they become pending - but
-calling C<ev_TYPE_stop> ensures that the watcher is neither active nor
-pending. If you want to free or reuse the memory used by the watcher it is
-therefore a good idea to always call its C<ev_TYPE_stop> function.
-
-=item bool ev_is_active (ev_TYPE *watcher)
-
-Returns a true value iff the watcher is active (i.e. it has been started
-and not yet been stopped). As long as a watcher is active you must not modify
-it.
-
-=item bool ev_is_pending (ev_TYPE *watcher)
-
-Returns a true value iff the watcher is pending, (i.e. it has outstanding
-events but its callback has not yet been invoked). As long as a watcher
-is pending (but not active) you must not call an init function on it (but
-C<ev_TYPE_set> is safe), you must not change its priority, and you must
-make sure the watcher is available to libev (e.g. you cannot C<free ()>
-it).
-
-=item callback ev_cb (ev_TYPE *watcher)
-
-Returns the callback currently set on the watcher.
-
-=item ev_set_cb (ev_TYPE *watcher, callback)
-
-Change the callback. You can change the callback at virtually any time
-(modulo threads).
-
-=item ev_set_priority (ev_TYPE *watcher, int priority)
-
-=item int ev_priority (ev_TYPE *watcher)
-
-Set and query the priority of the watcher. The priority is a small
-integer between C<EV_MAXPRI> (default: C<2>) and C<EV_MINPRI>
-(default: C<-2>). Pending watchers with higher priority will be invoked
-before watchers with lower priority, but priority will not keep watchers
-from being executed (except for C<ev_idle> watchers).
-
-If you need to suppress invocation when higher priority events are pending
-you need to look at C<ev_idle> watchers, which provide this functionality.
-
-You I<must not> change the priority of a watcher as long as it is active or
-pending.
-
-Setting a priority outside the range of C<EV_MINPRI> to C<EV_MAXPRI> is
-fine, as long as you do not mind that the priority value you query might
-or might not have been clamped to the valid range.
-
-The default priority used by watchers when no priority has been set is
-always C<0>, which is supposed to not be too high and not be too low :).
-
-See L</WATCHER PRIORITY MODELS>, below, for a more thorough treatment of
-priorities.
-
-=item ev_invoke (loop, ev_TYPE *watcher, int revents)
-
-Invoke the C<watcher> with the given C<loop> and C<revents>. Neither
-C<loop> nor C<revents> need to be valid as long as the watcher callback
-can deal with that fact, as both are simply passed through to the
-callback.
-
-=item int ev_clear_pending (loop, ev_TYPE *watcher)
-
-If the watcher is pending, this function clears its pending status and
-returns its C<revents> bitset (as if its callback was invoked). If the
-watcher isn't pending it does nothing and returns C<0>.
-
-Sometimes it can be useful to "poll" a watcher instead of waiting for its
-callback to be invoked, which can be accomplished with this function.
-
-=item ev_feed_event (loop, ev_TYPE *watcher, int revents)
-
-Feeds the given event set into the event loop, as if the specified event
-had happened for the specified watcher (which must be a pointer to an
-initialised but not necessarily started event watcher). Obviously you must
-not free the watcher as long as it has pending events.
-
-Stopping the watcher, letting libev invoke it, or calling
-C<ev_clear_pending> will clear the pending event, even if the watcher was
-not started in the first place.
-
-See also C<ev_feed_fd_event> and C<ev_feed_signal_event> for related
-functions that do not need a watcher.

-OWN COMPOSITE WATCHERS> idioms.
-
-=head2 WATCHER STATES
-
-There are various watcher states mentioned throughout this manual -
-active, pending and so on. In this section these states and the rules to
-transition between them will be described in more detail - and while these
-rules might look complicated, they usually do "the right thing".
-
-=over 4
-
-=item initialised
-
-Before a watcher can be registered with the event loop it has to be
-initialised. This can be done with a call to C<ev_TYPE_init>, or calls to
-C<ev_init> followed by the watcher-specific C<ev_TYPE_set> function.
-
-In this state it is simply some block of memory that is suitable for
-use in an event loop. It can be moved around, freed, reused etc. at
-will - as long as you either keep the memory contents intact, or call
-C<ev_TYPE_init> again.
-
-=item started/running/active
-
-Once a watcher has been started with a call to C<ev_TYPE_start> it becomes
-property of the event loop, and is actively waiting for events. While in
-this state it cannot be accessed (except in a few documented ways), moved,
-freed or anything else - the only legal thing is to keep a pointer to it,
-and call libev functions on it that are documented to work on active watchers.
-
-=item pending
-
-If a watcher is active and libev determines that an event it is interested
-in has occurred (such as a timer expiring), it will become pending. It will
-stay in this pending state until either it is stopped or its callback is
-about to be invoked, so it is not normally pending inside the watcher
-callback.
-
-The watcher might or might not be active while it is pending (for example,
-an expired non-repeating timer can be pending but no longer active). If it
-is stopped, it can be freely accessed (e.g. by calling C<ev_TYPE_set>),
-but it is still property of the event loop at this time, so cannot be
-moved, freed or reused. And if it is active the rules described in the
-previous item still apply.
-
-It is also possible to feed an event on a watcher that is not active (e.g.
-via C<ev_feed_event>), in which case it becomes pending without being
-active.
-
-=item stopped
-
-A watcher can be stopped implicitly by libev (in which case it might still
-be pending), or explicitly by calling its C<ev_TYPE_stop> function. The
-latter will clear any pending state the watcher might be in, regardless
-of whether it was active or not, so stopping a watcher explicitly before
-freeing it is often a good idea.
-
-While stopped (and not pending) the watcher is essentially in the
-initialised state, that is, it can be reused, moved, modified in any way
-you wish (but when you trash the memory block, you need to C<ev_TYPE_init>
-it again).
-
-=back
-
-=head2 WATCHER PRIORITY MODELS
-
-Many event loops support I<watcher priorities>, which are usually small
-integers that influence the ordering of event callback invocation
-between watchers in some way, all else being equal.
-
-In libev, Watcher priorities can be set using C<ev_set_priority>. See its
-description for the more technical details such as the actual priority
-range.
-
-There are two common ways how these these priorities are being interpreted
-by event loops:
-
-In the more common lock-out model, higher priorities "lock out" invocation
-of lower priority watchers, which means as long as higher priority
-watchers receive events, lower priority watchers are not being invoked.
-
-The less common only-for-ordering model uses priorities solely to order
-callback invocation within a single event loop iteration: Higher priority
-watchers are invoked before lower priority ones, but they all get invoked
-before polling for new events.
-
-Libev uses the second (only-for-ordering) model for all its watchers
-except for idle watchers (which use the lock-out model).
-
-The rationale behind this is that implementing the lock-out model for
-watchers is not well supported by most kernel interfaces, and most event
-libraries will just poll for the same events again and again as long as
-their callbacks have not been executed, which is very inefficient in the
-common case of one high-priority watcher locking out a mass of lower
-priority ones.
-
-Static (ordering) priorities are most useful when you have two or more
-watchers handling the same resource: a typical usage example is having an
-C<ev_io> watcher to receive data, and an associated C<ev_timer> to handle
-timeouts. Under load, data might be received while the program handles
-other jobs, but since timers normally get invoked first, the timeout
-handler will be executed before checking for data. In that case, giving
-the timer a lower priority than the I/O watcher ensures that I/O will be
-handled first even under adverse conditions (which is usually, but not
-always, what you want).
-
-Since idle watchers use the "lock-out" model, meaning that idle watchers
-will only be executed when no same or higher priority watchers have
-received events, they can be used to implement the "lock-out" model when
-required.
-
-For example, to emulate how many other event libraries handle priorities,
-you can associate an C<ev_idle> watcher to each such watcher, and in
-the normal watcher callback, you just start the idle watcher. The real
-processing is done in the idle watcher callback. This causes libev to
-continuously poll and process kernel event data for the watcher, but when
-the lock-out case is known to be rare (which in turn is rare :), this is
-workable.
-
-Usually, however, the lock-out model implemented that way will perform
-miserably under the type of load it was designed to handle. In that case,
-it might be preferable to stop the real watcher before starting the
-idle watcher, so the kernel will not have to process the event in case
-the actual processing will be delayed for considerable time.
-
-Here is an example of an I/O watcher that should run at a strictly lower
-priority than the default, and which should only process data when no
-other events are pending:
-
- ev_idle idle; // actual processing watcher
- ev_io io; // actual event watcher
-
- static void
- io_cb (EV_P_ ev_io *w, int revents)
- {
- // stop the I/O watcher, we received the event, but
- // are not yet ready to handle it.
- ev_io_stop (EV_A_ w);
-
- // start the idle watcher to handle the actual event.
- // it will not be executed as long as other watchers
- // with the default priority are receiving events.
- ev_idle_start (EV_A_ &idle);
- }
-
- static void
- idle_cb (EV_P_ ev_idle *w, int revents)
- {
- // actual processing
- read (STDIN_FILENO, ...);
-
- // have to start the I/O watcher again, as
- // we have handled the event
- ev_io_start (EV_P_ &io);
- }
-
- // initialisation
- ev_idle_init (&idle, idle_cb);
- ev_io_init (&io, io_cb, STDIN_FILENO, EV_READ);
- ev_io_start (EV_DEFAULT_ &io);
-
-In the "real" world, it might also be beneficial to start a timer, so that
-low-priority connections can not be locked out forever under load. This
-enables your program to keep a lower latency for important connections
-during short periods of high load, while not completely locking out less
-important ones.
-
-
-=head1 WATCHER TYPES
-
-This section describes each watcher in detail, but will not repeat
-information given in the last section. Any initialisation/set macros,
-functions and members specific to the watcher type are explained.
-
-Members are additionally marked with either I<[read-only]>, meaning that,
-while the watcher is active, you can look at the member and expect some
-sensible content, but you must not modify it (you can modify it while the
-watcher is stopped to your hearts content), or I<[read-write]>, which
-means you can expect it to have some sensible content while the watcher
-is active, but you can also modify it. Modifying it may not do something
-sensible or take immediate effect (or do anything at all), but libev will
-not crash or malfunction in any way.
-
-
-=head2 C<ev_io> - is this file descriptor readable or writable?
-
-I/O watchers check whether a file descriptor is readable or writable
-in each iteration of the event loop, or, more precisely, when reading
-would not block the process and writing would at least be able to write
-some data. This behaviour is called level-triggering because you keep
-receiving events as long as the condition persists. Remember you can stop
-the watcher if you don't want to act on the event and neither want to
-receive future events.
-
-In general you can register as many read and/or write event watchers per
-fd as you want (as long as you don't confuse yourself). Setting all file
-descriptors to non-blocking mode is also usually a good idea (but not
-required if you know what you are doing).
-
-Another thing you have to watch out for is that it is quite easy to
-receive "spurious" readiness notifications, that is, your callback might
-be called with C<EV_READ> but a subsequent C<read>(2) will actually block
-because there is no data. It is very easy to get into this situation even
-with a relatively standard program structure. Thus it is best to always
-use non-blocking I/O: An extra C<read>(2) returning C<EAGAIN> is far
-preferable to a program hanging until some data arrives.
-
-If you cannot run the fd in non-blocking mode (for example you should
-not play around with an Xlib connection), then you have to separately
-re-test whether a file descriptor is really ready with a known-to-be good
-interface such as poll (fortunately in the case of Xlib, it already does
-this on its own, so its quite safe to use). Some people additionally
-use C<SIGALRM> and an interval timer, just to be sure you won't block
-indefinitely.
-
-But really, best use non-blocking mode.
-
-=head3 The special problem of disappearing file descriptors
-
-Some backends (e.g. kqueue, epoll) need to be told about closing a file
-descriptor (either due to calling C<close> explicitly or any other means,
-such as C<dup2>). The reason is that you register interest in some file
-descriptor, but when it goes away, the operating system will silently drop
-this interest. If another file descriptor with the same number then is
-registered with libev, there is no efficient way to see that this is, in
-fact, a different file descriptor.
-
-To avoid having to explicitly tell libev about such cases, libev follows
-the following policy: Each time C<ev_io_set> is being called, libev
-will assume that this is potentially a new file descriptor, otherwise
-it is assumed that the file descriptor stays the same. That means that
-you I<have> to call C<ev_io_set> (or C<ev_io_init>) when you change the
-descriptor even if the file descriptor number itself did not change.
-
-This is how one would do it normally anyway, the important point is that
-the libev application should not optimise around libev but should leave
-optimisations to libev.
-
-=head3 The special problem of dup'ed file descriptors
-
-Some backends (e.g. epoll), cannot register events for file descriptors,
-but only events for the underlying file descriptions. That means when you
-have C<dup ()>'ed file descriptors or weirder constellations, and register
-events for them, only one file descriptor might actually receive events.
-
-There is no workaround possible except not registering events
-for potentially C<dup ()>'ed file descriptors, or to resort to
-C<EVBACKEND_SELECT> or C<EVBACKEND_POLL>.
-
-=head3 The special problem of files
-
-Many people try to use C<select> (or libev) on file descriptors
-representing files, and expect it to become ready when their program
-doesn't block on disk accesses (which can take a long time on their own).
-
-However, this cannot ever work in the "expected" way - you get a readiness
-notification as soon as the kernel knows whether and how much data is
-there, and in the case of open files, that's always the case, so you
-always get a readiness notification instantly, and your read (or possibly
-write) will still block on the disk I/O.
-
-Another way to view it is that in the case of sockets, pipes, character
-devices and so on, there is another party (the sender) that delivers data
-on its own, but in the case of files, there is no such thing: the disk
-will not send data on its own, simply because it doesn't know what you
-wish to read - you would first have to request some data.
-
-Since files are typically not-so-well supported by advanced notification
-mechanism, libev tries hard to emulate POSIX behaviour with respect
-to files, even though you should not use it. The reason for this is
-convenience: sometimes you want to watch STDIN or STDOUT, which is
-usually a tty, often a pipe, but also sometimes files or special devices
-(for example, C<epoll> on Linux works with F</dev/random> but not with
-F</dev/urandom>), and even though the file might better be served with
-asynchronous I/O instead of with non-blocking I/O, it is still useful when
-it "just works" instead of freezing.
-
-So avoid file descriptors pointing to files when you know it (e.g. use
-libeio), but use them when it is convenient, e.g. for STDIN/STDOUT, or
-when you rarely read from a file instead of from a socket, and want to
-reuse the same code path.
-
-=head3 The special problem of fork
-
-Some backends (epoll, kqueue) do not support C<fork ()> at all or exhibit
-useless behaviour. Libev fully supports fork, but needs to be told about
-it in the child if you want to continue to use it in the child.
-
-To support fork in your child processes, you have to call C<ev_loop_fork
-()> after a fork in the child, enable C<EVFLAG_FORKCHECK>, or resort to
-C<EVBACKEND_SELECT> or C<EVBACKEND_POLL>.
-
-=head3 The special problem of SIGPIPE
-
-While not really specific to libev, it is easy to forget about C<SIGPIPE>:
-when writing to a pipe whose other end has been closed, your program gets
-sent a SIGPIPE, which, by default, aborts your program. For most programs
-this is sensible behaviour, for daemons, this is usually undesirable.
-
-So when you encounter spurious, unexplained daemon exits, make sure you
-ignore SIGPIPE (and maybe make sure you log the exit status of your daemon
-somewhere, as that would have given you a big clue).
-
-=head3 The special problem of accept()ing when you can't
-
-Many implementations of the POSIX C<accept> function (for example,
-found in post-2004 Linux) have the peculiar behaviour of not removing a
-connection from the pending queue in all error cases.
-
-For example, larger servers often run out of file descriptors (because
-of resource limits), causing C<accept> to fail with C<ENFILE> but not
-rejecting the connection, leading to libev signalling readiness on
-the next iteration again (the connection still exists after all), and
-typically causing the program to loop at 100% CPU usage.
-
-Unfortunately, the set of errors that cause this issue differs between
-operating systems, there is usually little the app can do to remedy the
-situation, and no known thread-safe method of removing the connection to
-cope with overload is known (to me).
-
-One of the easiest ways to handle this situation is to just ignore it
-- when the program encounters an overload, it will just loop until the
-situation is over. While this is a form of busy waiting, no OS offers an
-event-based way to handle this situation, so it's the best one can do.
-
-A better way to handle the situation is to log any errors other than
-C<EAGAIN> and C<EWOULDBLOCK>, making sure not to flood the log with such
-messages, and continue as usual, which at least gives the user an idea of
-what could be wrong ("raise the ulimit!"). For extra points one could stop
-the C<ev_io> watcher on the listening fd "for a while", which reduces CPU
-usage.
-
-If your program is single-threaded, then you could also keep a dummy file
-descriptor for overload situations (e.g. by opening F</dev/null>), and
-when you run into C<ENFILE> or C<EMFILE>, close it, run C<accept>,
-close that fd, and create a new dummy fd. This will gracefully refuse
-clients under typical overload conditions.
-
-The last way to handle it is to simply log the error and C<exit>, as
-is often done with C<malloc> failures, but this results in an easy
-opportunity for a DoS attack.

-
-=head2 C<ev_timer> - relative and optionally repeating timeouts
-
-Timer watchers are simple relative timers that generate an event after a
-given time, and optionally repeating in regular intervals after that.
-
-The timers are based on real time, that is, if you register an event that
-times out after an hour and you reset your system clock to January last
-year, it will still time out after (roughly) one hour. "Roughly" because
-detecting time jumps is hard, and some inaccuracies are unavoidable (the
-monotonic clock option helps a lot here).
-
-The callback is guaranteed to be invoked only I<after> its timeout has
-passed (not I<at>, so on systems with very low-resolution clocks this
-might introduce a small delay, see "the special problem of being too
-early", below). If multiple timers become ready during the same loop
-iteration then the ones with earlier time-out values are invoked before
-ones of the same priority with later time-out values (but this is no
-longer true when a callback calls C<ev_run> recursively).
-
-=head3 Be smart about timeouts
-
-Many real-world problems involve some kind of timeout, usually for error
-recovery. A typical example is an HTTP request - if the other side hangs,
-you want to raise some error after a while.
-
-What follows are some ways to handle this problem, from obvious and
-inefficient to smart and efficient.
-
-In the following, a 60 second activity timeout is assumed - a timeout that
-gets reset to 60 seconds each time there is activity (e.g. each time some
-data or other life sign was received).
-
-=over 4
-
-=item 1. Use a timer and stop, reinitialise and start it on activity.
-
-This is the most obvious, but not the most simple way: In the beginning,
-start the watcher:
-
- ev_timer_init (timer, callback, 60., 0.);
- ev_timer_start (loop, timer);
-
-Then, each time there is some activity, C<ev_timer_stop> it, initialise it
-and start it again:
-
- ev_timer_stop (loop, timer);
- ev_timer_set (timer, 60., 0.);
- ev_timer_start (loop, timer);
-
-This is relatively simple to implement, but means that each time there is
-some activity, libev will first have to remove the timer from its internal
-data structure and then add it again. Libev tries to be fast, but it's
-still not a constant-time operation.
-
-=item 2. Use a timer and re-start it with C<ev_timer_again> inactivity.
-
-This is the easiest way, and involves using C<ev_timer_again> instead of
-C<ev_timer_start>.
-
-To implement this, configure an C<ev_timer> with a C<repeat> value
-of C<60> and then call C<ev_timer_again> at start and each time you
-successfully read or write some data. If you go into an idle state where
-you do not expect data to travel on the socket, you can C<ev_timer_stop>
-the timer, and C<ev_timer_again> will automatically restart it if need be.
-
-That means you can ignore both the C<ev_timer_start> function and the
-C<after> argument to C<ev_timer_set>, and only ever use the C<repeat>
-member and C<ev_timer_again>.
-
-At start:
-
- ev_init (timer, callback);
- timer->repeat = 60.;
- ev_timer_again (loop, timer);
-
-Each time there is some activity:
-
- ev_timer_again (loop, timer);
-
-It is even possible to change the time-out on the fly, regardless of
-whether the watcher is active or not:
-
- timer->repeat = 30.;
- ev_timer_again (loop, timer);
-
-This is slightly more efficient then stopping/starting the timer each time
-you want to modify its timeout value, as libev does not have to completely
-remove and re-insert the timer from/into its internal data structure.
-
-It is, however, even simpler than the "obvious" way to do it.
-
-=item 3. Let the timer time out, but then re-arm it as required.
-
-This method is more tricky, but usually most efficient: Most timeouts are
-relatively long compared to the intervals between other activity - in
-our example, within 60 seconds, there are usually many I/O events with
-associated activity resets.
-
-In this case, it would be more efficient to leave the C<ev_timer> alone,
-but remember the time of last activity, and check for a real timeout only
-within the callback:
-
- ev_tstamp timeout = 60.;
- ev_tstamp last_activity; // time of last activity
- ev_timer timer;
-
- static void
- callback (EV_P_ ev_timer *w, int revents)
- {
- // calculate when the timeout would happen
- ev_tstamp after = last_activity - ev_now (EV_A) + timeout;
-
- // if negative, it means we the timeout already occurred
- if (after < 0.)
- {
- // timeout occurred, take action
- }
- else
- {
- // callback was invoked, but there was some recent
- // activity. simply restart the timer to time out
- // after "after" seconds, which is the earliest time
- // the timeout can occur.
- ev_timer_set (w, after, 0.);
- ev_timer_start (EV_A_ w);
- }
- }
-
-To summarise the callback: first calculate in how many seconds the
-timeout will occur (by calculating the absolute time when it would occur,
-C<last_activity + timeout>, and subtracting the current time, C<ev_now
-(EV_A)> from that).
-
-If this value is negative, then we are already past the timeout, i.e. we
-timed out, and need to do whatever is needed in this case.
-
-Otherwise, we now the earliest time at which the timeout would trigger,
-and simply start the timer with this timeout value.
-
-In other words, each time the callback is invoked it will check whether
-the timeout occurred. If not, it will simply reschedule itself to check
-again at the earliest time it could time out. Rinse. Repeat.
-
-This scheme causes more callback invocations (about one every 60 seconds
-minus half the average time between activity), but virtually no calls to
-libev to change the timeout.
-
-To start the machinery, simply initialise the watcher and set
-C<last_activity> to the current time (meaning there was some activity just
-now), then call the callback, which will "do the right thing" and start
-the timer:
-
- last_activity = ev_now (EV_A);
- ev_init (&timer, callback);
- callback (EV_A_ &timer, 0);
-
-When there is some activity, simply store the current time in
-C<last_activity>, no libev calls at all:
-
- if (activity detected)
- last_activity = ev_now (EV_A);
-
-When your timeout value changes, then the timeout can be changed by simply
-providing a new value, stopping the timer and calling the callback, which
-will again do the right thing (for example, time out immediately :).
-
- timeout = new_value;
- ev_timer_stop (EV_A_ &timer);
- callback (EV_A_ &timer, 0);
-
-This technique is slightly more complex, but in most cases where the
-time-out is unlikely to be triggered, much more efficient.
-
-=item 4. Wee, just use a double-linked list for your timeouts.
-
-If there is not one request, but many thousands (millions...), all
-employing some kind of timeout with the same timeout value, then one can
-do even better:
-
-When starting the timeout, calculate the timeout value and put the timeout
-at the I<end> of the list.
-
-Then use an C<ev_timer> to fire when the timeout at the I<beginning> of
-the list is expected to fire (for example, using the technique #3).
-
-When there is some activity, remove the timer from the list, recalculate
-the timeout, append it to the end of the list again, and make sure to
-update the C<ev_timer> if it was taken from the beginning of the list.
-
-This way, one can manage an unlimited number of timeouts in O(1) time for
-starting, stopping and updating the timers, at the expense of a major
-complication, and having to use a constant timeout. The constant timeout
-ensures that the list stays sorted.
-
-=back
-
-So which method the best?
-
-Method #2 is a simple no-brain-required solution that is adequate in most
-situations. Method #3 requires a bit more thinking, but handles many cases
-better, and isn't very complicated either. In most case, choosing either
-one is fine, with #3 being better in typical situations.
-
-Method #1 is almost always a bad idea, and buys you nothing. Method #4 is
-rather complicated, but extremely efficient, something that really pays
-off after the first million or so of active timers, i.e. it's usually
-overkill :)
-
-=head3 The special problem of being too early
-
-If you ask a timer to call your callback after three seconds, then
-you expect it to be invoked after three seconds - but of course, this
-cannot be guaranteed to infinite precision. Less obviously, it cannot be
-guaranteed to any precision by libev - imagine somebody suspending the
-process with a STOP signal for a few hours for example.
-
-So, libev tries to invoke your callback as soon as possible I<after> the
-delay has occurred, but cannot guarantee this.
-
-A less obvious failure mode is calling your callback too early: many event
-loops compare timestamps with a "elapsed delay >= requested delay", but
-this can cause your callback to be invoked much earlier than you would
-expect.
-
-To see why, imagine a system with a clock that only offers full second
-resolution (think windows if you can't come up with a broken enough OS
-yourself). If you schedule a one-second timer at the time 500.9, then the
-event loop will schedule your timeout to elapse at a system time of 500
-(500.9 truncated to the resolution) + 1, or 501.
-
-If an event library looks at the timeout 0.1s later, it will see "501 >=
-501" and invoke the callback 0.1s after it was started, even though a
-one-second delay was requested - this is being "too early", despite best
-intentions.
-
-This is the reason why libev will never invoke the callback if the elapsed
-delay equals the requested delay, but only when the elapsed delay is
-larger than the requested delay. In the example above, libev would only invoke
-the callback at system time 502, or 1.1s after the timer was started.
-
-So, while libev cannot guarantee that your callback will be invoked
-exactly when requested, it I<can> and I<does> guarantee that the requested
-delay has actually elapsed, or in other words, it always errs on the "too
-late" side of things.
-
-=head3 The special problem of time updates
-
-Establishing the current time is a costly operation (it usually takes
-at least one system call): EV therefore updates its idea of the current
-time only before and after C<ev_run> collects new events, which causes a
-growing difference between C<ev_now ()> and C<ev_time ()> when handling
-lots of events in one iteration.
-
-The relative timeouts are calculated relative to the C<ev_now ()>
-time. This is usually the right thing as this timestamp refers to the time
-of the event triggering whatever timeout you are modifying/starting. If
-you suspect event processing to be delayed and you I<need> to base the
-timeout on the current time, use something like this to adjust for this:
-
- ev_timer_set (&timer, after + ev_now () - ev_time (), 0.);
-
-If the event loop is suspended for a long time, you can also force an
-update of the time returned by C<ev_now ()> by calling C<ev_now_update
-()>.
-
-=head3 The special problem of unsynchronised clocks
-
-Modern systems have a variety of clocks - libev itself uses the normal
-"wall clock" clock and, if available, the monotonic clock (to avoid time
-jumps).
-
-Neither of these clocks is synchronised with each other or any other clock
-on the system, so C<ev_time ()> might return a considerably different time
-than C<gettimeofday ()> or C<time ()>. On a GNU/Linux system, for example,
-a call to C<gettimeofday> might return a second count that is one higher
-than a directly following call to C<time>.
-
-The moral of this is to only compare libev-related timestamps with
-C<ev_time ()> and C<ev_now ()>, at least if you want better precision than
-a second or so.
-
-One more problem arises due to this lack of synchronisation: if libev uses
-the system monotonic clock and you compare timestamps from C<ev_time>
-or C<ev_now> from when you started your timer and when your callback is
-invoked, you will find that sometimes the callback is a bit "early".
-
-This is because C<ev_timer>s work in real time, not wall clock time, so
-libev makes sure your callback is not invoked before the delay happened,
-I<measured according to the real time>, not the system clock.
-
-If your timeouts are based on a physical timescale (e.g. "time out this
-connection after 100 seconds") then this shouldn't bother you as it is
-exactly the right behaviour.
-
-If you want to compare wall clock/system timestamps to your timers, then
-you need to use C<ev_periodic>s, as these are based on the wall clock
-time, where your comparisons will always generate correct results.
-
-=head3 The special problems of suspended animation
-
-When you leave the server world it is quite customary to hit machines that
-can suspend/hibernate - what happens to the clocks during such a suspend?
-
-Some quick tests made with a Linux 2.6.28 indicate that a suspend freezes
-all processes, while the clocks (C<times>, C<CLOCK_MONOTONIC>) continue
-to run until the system is suspended, but they will not advance while the
-system is suspended. That means, on resume, it will be as if the program
-was frozen for a few seconds, but the suspend time will not be counted
-towards C<ev_timer> when a monotonic clock source is used. The real time
-clock advanced as expected, but if it is used as sole clocksource, then a
-long suspend would be detected as a time jump by libev, and timers would
-be adjusted accordingly.
-
-I would not be surprised to see different behaviour in different between
-operating systems, OS versions or even different hardware.
-
-The other form of suspend (job control, or sending a SIGSTOP) will see a
-time jump in the monotonic clocks and the realtime clock. If the program
-is suspended for a very long time, and monotonic clock sources are in use,
-then you can expect C<ev_timer>s to expire as the full suspension time
-will be counted towards the timers. When no monotonic clock source is in
-use, then libev will again assume a timejump and adjust accordingly.
-
-It might be beneficial for this latter case to call C<ev_suspend>
-and C<ev_resume> in code that handles C<SIGTSTP>, to at least get
-deterministic behaviour in this case (you can do nothing against
-C<SIGSTOP>).

-Configure the timer to trigger after C<after> seconds. If C<repeat>

-reached. If it is positive, then the timer will automatically be
-configured to trigger again C<repeat> seconds later, again, and again,

-The timer itself will do a best-effort at avoiding drift, that is, if

-
-=head2 C<ev_periodic> - to cron or not to cron?
-
-Periodic watchers are also timers of a kind, but they are very versatile
-(and unfortunately a bit complex).
-
-Unlike C<ev_timer>, periodic watchers are not based on real time (or
-relative time, the physical time that passes) but on wall clock time
-(absolute time, the thing you can read on your calender or clock). The
-difference is that wall clock time can run faster or slower than real
-time, and time jumps are not uncommon (e.g. when you adjust your
-wrist-watch).
-
-You can tell a periodic watcher to trigger after some specific point
-in time: for example, if you tell a periodic watcher to trigger "in 10
-seconds" (by specifying e.g. C<ev_now () + 10.>, that is, an absolute time
-not a delay) and then reset your system clock to January of the previous
-year, then it will take a year or more to trigger the event (unlike an
-C<ev_timer>, which would still trigger roughly 10 seconds after starting
-it, as it uses a relative timeout).
-
-C<ev_periodic> watchers can also be used to implement vastly more complex
-timers, such as triggering an event on each "midnight, local time", or
-other complicated rules. This cannot be done with C<ev_timer> watchers, as
-those cannot react to time jumps.
-
-As with timers, the callback is guaranteed to be invoked only when the
-point in time where it is supposed to trigger has passed. If multiple
-timers become ready during the same loop iteration then the ones with
-earlier time-out values are invoked before ones with later time-out values
-(but this is no longer true when a callback calls C<ev_run> recursively).

-=item ev_periodic_init (ev_periodic *, callback, ev_tstamp offset, ev_tstamp interval, reschedule_cb)
-
-=item ev_periodic_set (ev_periodic *, ev_tstamp offset, ev_tstamp interval, reschedule_cb)
-
-Lots of arguments, let's sort it out... There are basically three modes of
-operation, and we will explain them from simplest to most complex:
-
-=over 4
-
-=item * absolute timer (offset = absolute time, interval = 0, reschedule_cb = 0)
-
-In this configuration the watcher triggers an event after the wall clock
-time C<offset> has passed. It will not repeat and will not adjust when a
-time jump occurs, that is, if it is to be run at January 1st 2011 then it
-will be stopped and invoked when the system clock reaches or surpasses
-this point in time.
-
-=item * repeating interval timer (offset = offset within interval, interval > 0, reschedule_cb = 0)
-
-In this mode the watcher will always be scheduled to time out at the next
-C<offset + N * interval> time (for some integer N, which can also be
-negative) and then repeat, regardless of any time jumps. The C<offset>
-argument is merely an offset into the C<interval> periods.
-
-This can be used to create timers that do not drift with respect to the
-system clock, for example, here is an C<ev_periodic> that triggers each
-hour, on the hour (with respect to UTC):
-
- ev_periodic_set (&periodic, 0., 3600., 0);
-
-This doesn't mean there will always be 3600 seconds in between triggers,
-but only that the callback will be called when the system time shows a
-full hour (UTC), or more correctly, when the system time is evenly divisible
-by 3600.
-
-Another way to think about it (for the mathematically inclined) is that
-C<ev_periodic> will try to run the callback in this mode at the next possible
-time where C<time = offset (mod interval)>, regardless of any time jumps.
-
-The C<interval> I<MUST> be positive, and for numerical stability, the
-interval value should be higher than C<1/8192> (which is around 100
-microseconds) and C<offset> should be higher than C<0> and should have
-at most a similar magnitude as the current time (say, within a factor of
-ten). Typical values for offset are, in fact, C<0> or something between
-C<0> and C<interval>, which is also the recommended range.
-
-Note also that there is an upper limit to how often a timer can fire (CPU
-speed for example), so if C<interval> is very small then timing stability
-will of course deteriorate. Libev itself tries to be exact to be about one
-millisecond (if the OS supports it and the machine is fast enough).
-
-=item * manual reschedule mode (offset ignored, interval ignored, reschedule_cb = callback)
-
-In this mode the values for C<interval> and C<offset> are both being
-ignored. Instead, each time the periodic watcher gets scheduled, the
-reschedule callback will be called with the watcher as first, and the
-current time as second argument.
-
-NOTE: I<This callback MUST NOT stop or destroy any periodic watcher, ever,
-or make ANY other event loop modifications whatsoever, unless explicitly
-allowed by documentation here>.
-
-If you need to stop it, return C<now + 1e30> (or so, fudge fudge) and stop
-it afterwards (e.g. by starting an C<ev_prepare> watcher, which is the
-only event loop modification you are allowed to do).
-
-The callback prototype is C<ev_tstamp (*reschedule_cb)(ev_periodic
-*w, ev_tstamp now)>, e.g.:
-
- static ev_tstamp
- my_rescheduler (ev_periodic *w, ev_tstamp now)
- {
- return now + 60.;
- }
-
-It must return the next time to trigger, based on the passed time value
-(that is, the lowest time value larger than to the second argument). It
-will usually be called just before the callback will be triggered, but
-might be called at other times, too.
-
-NOTE: I<< This callback must always return a time that is higher than or
-equal to the passed C<now> value >>.
-
-This can be used to create very complex timers, such as a timer that
-triggers on "next midnight, local time". To do this, you would calculate the
-next midnight after C<now> and return the timestamp value for this. How
-you do this is, again, up to you (but it is not trivial, which is the main
-reason I omitted it as an example).

-
-=item ev_periodic_again (loop, ev_periodic *)
-
-Simply stops and restarts the periodic watcher again. This is only useful

-
-When active, returns the absolute time that the watcher is supposed

-
-=head2 C<ev_signal> - signal me when a signal gets signalled!
-
-Signal watchers will trigger an event when the process receives a specific
-signal one or more times. Even though signals are very asynchronous, libev
-will try its best to deliver signals synchronously, i.e. as part of the
-normal event processing, like any other event.
-
-If you want signals to be delivered truly asynchronously, just use
-C<sigaction> as you would do without libev and forget about sharing
-the signal. You can even use C<ev_async> from a signal handler to
-synchronously wake up an event loop.
-
-You can configure as many watchers as you like for the same signal, but
-only within the same loop, i.e. you can watch for C<SIGINT> in your
-default loop and for C<SIGIO> in another loop, but you cannot watch for
-C<SIGINT> in both the default loop and another loop at the same time. At
-the moment, C<SIGCHLD> is permanently tied to the default loop.
-
-When the first watcher gets started will libev actually register something
-with the kernel (thus it coexists with your own signal handlers as long as
-you don't register any with libev for the same signal).
-
-If possible and supported, libev will install its handlers with
-C<SA_RESTART> (or equivalent) behaviour enabled, so system calls should
-not be unduly interrupted. If you have a problem with system calls getting
-interrupted by signals you can block all signals in an C<ev_check> watcher
-and unblock them in an C<ev_prepare> watcher.
-
-=head3 The special problem of inheritance over fork/execve/pthread_create
-
-Both the signal mask (C<sigprocmask>) and the signal disposition
-(C<sigaction>) are unspecified after starting a signal watcher (and after
-stopping it again), that is, libev might or might not block the signal,
-and might or might not set or restore the installed signal handler (but
-see C<EVFLAG_NOSIGMASK>).
-
-While this does not matter for the signal disposition (libev never
-sets signals to C<SIG_IGN>, so handlers will be reset to C<SIG_DFL> on
-C<execve>), this matters for the signal mask: many programs do not expect
-certain signals to be blocked.
-
-This means that before calling C<exec> (from the child) you should reset
-the signal mask to whatever "default" you expect (all clear is a good
-choice usually).
-
-The simplest way to ensure that the signal mask is reset in the child is
-to install a fork handler with C<pthread_atfork> that resets it. That will
-catch fork calls done by libraries (such as the libc) as well.
-
-In current versions of libev, the signal will not be blocked indefinitely
-unless you use the C<signalfd> API (C<EV_SIGNALFD>). While this reduces
-the window of opportunity for problems, it will not go away, as libev
-I<has> to modify the signal mask, at least temporarily.
-
-So I can't stress this enough: I<If you do not reset your signal mask when
-you expect it to be empty, you have a race condition in your code>. This
-is not a libev-specific thing, this is true for most event libraries.
-
-=head3 The special problem of threads signal handling
-
-POSIX threads has problematic signal handling semantics, specifically,
-a lot of functionality (sigfd, sigwait etc.) only really works if all
-threads in a process block signals, which is hard to achieve.
-
-When you want to use sigwait (or mix libev signal handling with your own
-for the same signals), you can tackle this problem by globally blocking
-all signals before creating any threads (or creating them with a fully set
-sigprocmask) and also specifying the C<EVFLAG_NOSIGMASK> when creating
-loops. Then designate one thread as "signal receiver thread" which handles
-these signals. You can pass on any signals that libev might be interested
-in by calling C<ev_feed_signal>.

-=head2 C<ev_child> - watch out for process status changes
-
-Child watchers trigger when your process receives a SIGCHLD in response to
-some child status changes (most typically when a child of yours dies or
-exits). It is permissible to install a child watcher I<after> the child
-has been forked (which implies it might have already exited), as long
-as the event loop isn't entered (or is continued from a watcher), i.e.,
-forking and then immediately registering a watcher for the child is fine,
-but forking and registering a watcher a few event loop iterations later or
-in the next callback invocation is not.
-
-Only the default event loop is capable of handling signals, and therefore
-you can only register child watchers in the default event loop.
-
-Due to some design glitches inside libev, child watchers will always be
-handled at maximum priority (their priority is set to C<EV_MAXPRI> by
-libev)
-
-=head3 Process Interaction
-
-Libev grabs C<SIGCHLD> as soon as the default event loop is
-initialised. This is necessary to guarantee proper behaviour even if the
-first child watcher is started after the child exits. The occurrence
-of C<SIGCHLD> is recorded asynchronously, but child reaping is done
-synchronously as part of the event loop processing. Libev always reaps all
-children, even ones not watched.
-
-=head3 Overriding the Built-In Processing
-
-Libev offers no special support for overriding the built-in child
-processing, but if your application collides with libev's default child
-handler, you can override it easily by installing your own handler for
-C<SIGCHLD> after initialising the default loop, and making sure the
-default loop never gets destroyed. You are encouraged, however, to use an
-event-based approach to child reaping and thus use libev's support for
-that, so other libev users can use C<ev_child> watchers freely.
-
-=head3 Stopping the Child Watcher
-
-Currently, the child watcher never gets stopped, even when the
-child terminates, so normally one needs to stop the watcher in the
-callback. Future versions of libev might stop the watcher automatically
-when a child exit is detected (calling C<ev_child_stop> twice is not a
-problem).

-
-=item ev_child_init (ev_child *, callback, int pid, int trace)
-
-=item ev_child_set (ev_child *, int pid, int trace)
-
-Configures the watcher to wait for status changes of process C<pid> (or
-I<any> process if C<pid> is specified as C<0>). The callback can look
-at the C<rstatus> member of the C<ev_child> watcher structure to see
-the status word (use the macros from C<sys/wait.h> and see your systems
-C<waitpid> documentation). The C<rpid> member contains the pid of the
-process causing the status change. C<trace> must be either C<0> (only
-activate the watcher when the process terminates) or C<1> (additionally
-activate the watcher when the process is stopped or continued).

-
-=head2 C<ev_stat> - did the file attributes just change?
-
-This watches a file system path for attribute changes. That is, it calls
-C<stat> on that path in regular intervals (or when the OS says it changed)
-and sees if it changed compared to the last time, invoking the callback
-if it did. Starting the watcher C<stat>'s the file, so only changes that
-happen after the watcher has been started will be reported.
-
-The path does not need to exist: changing from "path exists" to "path does
-not exist" is a status change like any other. The condition "path does not
-exist" (or more correctly "path cannot be stat'ed") is signified by the
-C<st_nlink> field being zero (which is otherwise always forced to be at
-least one) and all the other fields of the stat buffer having unspecified
-contents.
-
-The path I<must not> end in a slash or contain special components such as
-C<.> or C<..>. The path I<should> be absolute: If it is relative and
-your working directory changes, then the behaviour is undefined.
-
-Since there is no portable change notification interface available, the
-portable implementation simply calls C<stat(2)> regularly on the path
-to see if it changed somehow. You can specify a recommended polling
-interval for this case. If you specify a polling interval of C<0> (highly
-recommended!) then a I<suitable, unspecified default> value will be used
-(which you can expect to be around five seconds, although this might
-change dynamically). Libev will also impose a minimum interval which is
-currently around C<0.1>, but that's usually overkill.
-
-This watcher type is not meant for massive numbers of stat watchers,
-as even with OS-supported change notifications, this can be
-resource-intensive.
-
-At the time of this writing, the only OS-specific interface implemented
-is the Linux inotify interface (implementing kqueue support is left as an
-exercise for the reader. Note, however, that the author sees no way of
-implementing C<ev_stat> semantics with kqueue, except as a hint).
-
-=head3 ABI Issues (Largefile Support)
-
-Libev by default (unless the user overrides this) uses the default
-compilation environment, which means that on systems with large file
-support disabled by default, you get the 32 bit version of the stat
-structure. When using the library from programs that change the ABI to
-use 64 bit file offsets the programs will fail. In that case you have to
-compile libev with the same flags to get binary compatibility. This is
-obviously the case with any flags that change the ABI, but the problem is
-most noticeably displayed with ev_stat and large file support.
-
-The solution for this is to lobby your distribution maker to make large
-file interfaces available by default (as e.g. FreeBSD does) and not
-optional. Libev cannot simply switch on large file support because it has
-to exchange stat structures with application programs compiled using the
-default compilation environment.
-
-=head3 Inotify and Kqueue
-
-When C<inotify (7)> support has been compiled into libev and present at
-runtime, it will be used to speed up change detection where possible. The
-inotify descriptor will be created lazily when the first C<ev_stat>
-watcher is being started.
-
-Inotify presence does not change the semantics of C<ev_stat> watchers
-except that changes might be detected earlier, and in some cases, to avoid
-making regular C<stat> calls. Even in the presence of inotify support
-there are many cases where libev has to resort to regular C<stat> polling,
-but as long as kernel 2.6.25 or newer is used (2.6.24 and older have too
-many bugs), the path exists (i.e. stat succeeds), and the path resides on
-a local filesystem (libev currently assumes only ext2/3, jfs, reiserfs and
-xfs are fully working) libev usually gets away without polling.
-
-There is no support for kqueue, as apparently it cannot be used to
-implement this functionality, due to the requirement of having a file
-descriptor open on the object at all times, and detecting renames, unlinks
-etc. is difficult.
-
-=head3 C<stat ()> is a synchronous operation
-
-Libev doesn't normally do any kind of I/O itself, and so is not blocking
-the process. The exception are C<ev_stat> watchers - those call C<stat
-()>, which is a synchronous operation.
-
-For local paths, this usually doesn't matter: unless the system is very
-busy or the intervals between stat's are large, a stat call will be fast,
-as the path data is usually in memory already (except when starting the
-watcher).
-
-For networked file systems, calling C<stat ()> can block an indefinite
-time due to network issues, and even under good conditions, a stat call
-often takes multiple milliseconds.
-
-Therefore, it is best to avoid using C<ev_stat> watchers on networked
-paths, although this is fully supported by libev.
-
-=head3 The special problem of stat time resolution
-
-The C<stat ()> system call only supports full-second resolution portably,
-and even on systems where the resolution is higher, most file systems
-still only support whole seconds.
-
-That means that, if the time is the only thing that changes, you can
-easily miss updates: on the first update, C<ev_stat> detects a change and
-calls your callback, which does something. When there is another update
-within the same second, C<ev_stat> will be unable to detect unless the
-stat data does change in other ways (e.g. file size).
-
-The solution to this is to delay acting on a change for slightly more
-than a second (or till slightly after the next full second boundary), using
-a roughly one-second-delay C<ev_timer> (e.g. C<ev_timer_set (w, 0., 1.02);
-ev_timer_again (loop, w)>).
-
-The C<.02> offset is added to work around small timing inconsistencies
-of some operating systems (where the second counter of the current time
-might be be delayed. One such system is the Linux kernel, where a call to
-C<gettimeofday> might return a timestamp with a full second later than
-a subsequent C<time> call - if the equivalent of C<time ()> is used to
-update file times then there will be a small window where the kernel uses
-the previous second to update file times but libev might already execute
-the timer callback).

-=item ev_stat_init (ev_stat *, callback, const char *path, ev_tstamp interval)
-
-=item ev_stat_set (ev_stat *, const char *path, ev_tstamp interval)
-
-Configures the watcher to wait for status changes of the given
-C<path>. The C<interval> is a hint on how quickly a change is expected to
-be detected and should normally be specified as C<0> to let libev choose
-a suitable value. The memory pointed to by C<path> must point to the same
-path for as long as the watcher is active.

-The callback will receive an C<EV_STAT> event when a change was detected,
-relative to the attributes at the time the watcher was started (or the
-last change was detected).
-
-=item ev_stat_stat (loop, ev_stat *)
-
-Updates the stat buffer immediately with new values. If you change the

-the only one changing the path). Can also be useful simply to find out the

-=head2 C<ev_idle> - when you've got nothing better to do...
-
-Idle watchers trigger events when no other events of the same or higher
-priority are pending (prepare, check and other idle watchers do not count
-as receiving "events").
-
-That is, as long as your process is busy handling sockets or timeouts
-(or even signals, imagine) of the same or higher priority it will not be
-triggered. But when your process is idle (or only lower-priority watchers
-are pending), the idle watchers are being called once per event loop
-iteration - until stopped, that is, or your process receives more events
-and becomes busy again with higher priority stuff.
-
-The most noteworthy effect is that as long as any idle watchers are
-active, the process will not block when waiting for new events.
-
-Apart from keeping your process non-blocking (which is a useful
-effect on its own sometimes), idle watchers are a good place to do
-"pseudo-background processing", or delay processing stuff to after the
-event loop has handled all outstanding events.
-
-=head3 Abusing an C<ev_idle> watcher for its side-effect
-
-As long as there is at least one active idle watcher, libev will never
-sleep unnecessarily. Or in other words, it will loop as fast as possible.
-For this to work, the idle watcher doesn't need to be invoked at all - the
-lowest priority will do.
-
-This mode of operation can be useful together with an C<ev_check> watcher,
-to do something on each event loop iteration - for example to balance load
-between different connections.

-See L</Abusing an ev_check watcher for its side-effect> for a longer

-
-=head2 C<ev_prepare> and C<ev_check> - customise your event loop!
-
-Prepare and check watchers are often (but not always) used in pairs:
-prepare watchers get invoked before the process blocks and check watchers
-afterwards.
-
-You I<must not> call C<ev_run> or similar functions that enter
-the current event loop from either C<ev_prepare> or C<ev_check>
-watchers. Other loops than the current one are fine, however. The
-rationale behind this is that you do not need to check for recursion in
-those watchers, i.e. the sequence will always be C<ev_prepare>, blocking,
-C<ev_check> so if you have one watcher of each kind they will always be
-called in pairs bracketing the blocking call.
-
-Their main purpose is to integrate other event mechanisms into libev and
-their use is somewhat advanced. They could be used, for example, to track
-variable changes, implement your own watchers, integrate net-snmp or a
-coroutine library and lots more. They are also occasionally useful if
-you cache some data and want to flush it before blocking (for example,
-in X programs you might want to do an C<XFlush ()> in an C<ev_prepare>
-watcher).
-
-This is done by examining in each prepare call which file descriptors
-need to be watched by the other library, registering C<ev_io> watchers
-for them and starting an C<ev_timer> watcher for any timeouts (many
-libraries provide exactly this functionality). Then, in the check watcher,
-you check for any events that occurred (by checking the pending status
-of all watchers and stopping them) and call back into the library. The
-I/O and timer callbacks will never actually be called (but must be valid
-nevertheless, because you never know, you know?).
-
-As another example, the Perl Coro module uses these hooks to integrate
-coroutines into libev programs, by yielding to other active coroutines
-during each prepare and only letting the process block if no coroutines
-are ready to run (it's actually more complicated: it only runs coroutines
-with priority higher than or equal to the event loop and one coroutine
-of lower priority, but only once, using idle watchers to keep the event
-loop from blocking if lower-priority coroutines are active, thus mapping
-low-priority coroutines to idle/background tasks).
-
-When used for this purpose, it is recommended to give C<ev_check> watchers
-highest (C<EV_MAXPRI>) priority, to ensure that they are being run before
-any other watchers after the poll (this doesn't matter for C<ev_prepare>
-watchers).
-
-Also, C<ev_check> watchers (and C<ev_prepare> watchers, too) should not
-activate ("feed") events into libev. While libev fully supports this, they
-might get executed before other C<ev_check> watchers did their job. As
-C<ev_check> watchers are often used to embed other (non-libev) event
-loops those other event loops might be in an unusable state until their
-C<ev_check> watcher ran (always remind yourself to coexist peacefully with
-others).
-
-=head3 Abusing an C<ev_check> watcher for its side-effect
-
-C<ev_check> (and less often also C<ev_prepare>) watchers can also be
-useful because they are called once per event loop iteration. For
-example, if you want to handle a large number of connections fairly, you
-normally only do a bit of work for each active connection, and if there
-is more work to do, you wait for the next event loop iteration, so other
-connections have a chance of making progress.
-
-Using an C<ev_check> watcher is almost enough: it will be called on the
-next event loop iteration. However, that isn't as soon as possible -
-without external events, your C<ev_check> watcher will not be invoked.
-
-This is where C<ev_idle> watchers come in handy - all you need is a
-single global idle watcher that is active as long as you have one active
-C<ev_check> watcher. The C<ev_idle> watcher makes sure the event loop
-will not sleep, and the C<ev_check> watcher makes sure a callback gets
-invoked. Neither watcher alone can do that.

-=head3 Examples
-
-There are a number of principal ways to embed other event loops or modules
-into libev. Here are some ideas on how to include libadns into libev
-(there is a Perl module named C<EV::ADNS> that does this, which you could
-use as a working example. Another Perl module named C<EV::Glib> embeds a
-Glib main context into libev, and finally, C<Glib::EV> embeds EV into the
-Glib event loop).
-
-Method 1: Add IO watchers and a timeout watcher in a prepare handler,
-and in a check watcher, destroy them and call into libadns. What follows
-is pseudo-code only of course. This requires you to either use a low
-priority for the check watcher or use C<ev_clear_pending> explicitly, as
-the callbacks for the IO/timeout watchers might not have been called yet.

- static ev_timer tw;

-
- // create one ev_io per pollfd
- for (int i = 0; i < nfd; ++i)
- {
- ev_io_init (iow + i, io_cb, fds [i].fd,
- ((fds [i].events & POLLIN ? EV_READ : 0)
- | (fds [i].events & POLLOUT ? EV_WRITE : 0)));
-
- fds [i].revents = 0;
- ev_io_start (loop, iow + i);
- }

- struct pollfd *fd = fds + i;
- int revents = ev_clear_pending (iow + i);
- if (revents & EV_READ ) fd->revents |= fd->events & POLLIN;
- if (revents & EV_WRITE) fd->revents |= fd->events & POLLOUT;

- // now stop the watcher
- ev_io_stop (loop, iow + i);
- }
-
- adns_afterpoll (adns, fds, nfd, timeval_from (ev_now (loop));
- }
-
-Method 2: This would be just like method 1, but you run C<adns_afterpoll>
-in the prepare watcher and would dispose of the check watcher.
-
-Method 3: If the module to be embedded supports explicit event
-notification (libadns does), you can also make use of the actual watcher
-callbacks, and only destroy/create the watchers in the prepare watcher.

- if (revents & EV_WRITE) adns_processwriteable (ads, w->fd, &tv_now);

-
- // do not ever call adns_afterpoll
-
-Method 4: Do not use a prepare or check watcher because the module you
-want to embed is not flexible enough to support it. Instead, you can
-override their poll function. The drawback with this solution is that the
-main loop is now no longer controllable by EV. The C<Glib::EV> module uses
-this approach, effectively embedding EV as a client into the horrible
-libglib event loop.

-=head2 C<ev_embed> - when one backend isn't enough...
-
-This is a rather advanced watcher type that lets you embed one event loop
-into another (currently only C<ev_io> events are supported in the embedded
-loop, other types of watchers might be handled in a delayed or incorrect
-fashion and must not be used).
-
-There are primarily two reasons you would want that: work around bugs and
-prioritise I/O.
-
-As an example for a bug workaround, the kqueue backend might only support
-sockets on some platform, so it is unusable as generic backend, but you
-still want to make use of it because you have many sockets and it scales
-so nicely. In this case, you would create a kqueue-based loop and embed
-it into your default loop (which might use e.g. poll). Overall operation
-will be a bit slower because first libev has to call C<poll> and then
-C<kevent>, but at least you can use both mechanisms for what they are
-best: C<kqueue> for scalable sockets and C<poll> if you want it to work :)
-
-As for prioritising I/O: under rare circumstances you have the case where
-some fds have to be watched and handled very quickly (with low latency),
-and even priorities and idle watchers might have too much overhead. In
-this case you would put all the high priority stuff in one loop and all
-the rest in a second one, and embed the second one in the first.
-
-As long as the watcher is active, the callback will be invoked every
-time there might be events pending in the embedded loop. The callback
-must then call C<ev_embed_sweep (mainloop, watcher)> to make a single
-sweep and invoke their callbacks (the callback doesn't need to invoke the
-C<ev_embed_sweep> function directly, it could also start an idle watcher
-to give the embedded loop strictly lower priority for example).
-
-You can also set the callback to C<0>, in which case the embed watcher
-will automatically execute the embedded loop sweep whenever necessary.
-
-Fork detection will be handled transparently while the C<ev_embed> watcher
-is active, i.e., the embedded loop will automatically be forked when the
-embedding loop forks. In other cases, the user is responsible for calling
-C<ev_loop_fork> on the embedded loop.
-
-Unfortunately, not all backends are embeddable: only the ones returned by
-C<ev_embeddable_backends> are, which, unfortunately, does not include any
-portable one.
-
-So when you want to use this feature you will always have to be prepared
-that you cannot get an embeddable loop. The recommended way to get around
-this is to have a separate variables for your embeddable loop, try to
-create it, and if that fails, use the normal loop for everything.
-
-=head3 C<ev_embed> and fork
-
-While the C<ev_embed> watcher is running, forks in the embedding loop will
-automatically be applied to the embedded loop as well, so no special
-fork handling is required in that case. When the watcher is not running,
-however, it is still the task of the libev user to call C<ev_loop_fork ()>
-as applicable.

-=head3 Examples
-
-Example: Try to get an embeddable event loop and embed it into the default
-event loop. If that is not possible, use the default loop. The default
-loop is stored in C<loop_hi>, while the embeddable loop is stored in
-C<loop_lo> (which is C<loop_hi> in the case no embeddable loop can be
-used).
-
- struct ev_loop *loop_hi = ev_default_init (0);
- struct ev_loop *loop_lo = 0;
- ev_embed embed;
-
- // see if there is a chance of getting one that works
- // (remember that a flags value of 0 means autodetection)
- loop_lo = ev_embeddable_backends () & ev_recommended_backends ()
- ? ev_loop_new (ev_embeddable_backends () & ev_recommended_backends ())
- : 0;
-
- // if we got one, then embed it, otherwise default to loop_hi
- if (loop_lo)
- {
- ev_embed_init (&embed, 0, loop_lo);
- ev_embed_start (loop_hi, &embed);
- }
- else
- loop_lo = loop_hi;
-
-Example: Check if kqueue is available but not recommended and create
-a kqueue backend for use with sockets (which usually work with any
-kqueue implementation). Store the kqueue/socket-only event loop in
-C<loop_socket>. (One might optionally use C<EVFLAG_NOENV>, too).
-
- struct ev_loop *loop = ev_default_init (0);
- struct ev_loop *loop_socket = 0;
- ev_embed embed;
-
- if (ev_supported_backends () & ~ev_recommended_backends () & EVBACKEND_KQUEUE)
- if ((loop_socket = ev_loop_new (EVBACKEND_KQUEUE))
- {
- ev_embed_init (&embed, 0, loop_socket);
- ev_embed_start (loop, &embed);
- }
-
- if (!loop_socket)
- loop_socket = loop;
-
- // now use loop_socket for all sockets, and loop for everything else
-
-
-=head2 C<ev_fork> - the audacity to resume the event loop after a fork
-
-Fork watchers are called when a C<fork ()> was detected (usually because
-whoever is a good citizen cared to tell libev about it by calling
-C<ev_loop_fork>). The invocation is done before the event loop blocks next
-and before C<ev_check> watchers are being called, and only in the child
-after the fork. If whoever good citizen calling C<ev_default_fork> cheats
-and calls it in the wrong process, the fork handlers will be invoked, too,
-of course.
-
-=head3 The special problem of life after fork - how is it possible?
-
-Most uses of C<fork()> consist of forking, then some simple calls to set
-up/change the process environment, followed by a call to C<exec()>. This
-sequence should be handled by libev without any problems.
-
-This changes when the application actually wants to do event handling
-in the child, or both parent in child, in effect "continuing" after the
-fork.
-
-The default mode of operation (for libev, with application help to detect
-forks) is to duplicate all the state in the child, as would be expected
-when I<either> the parent I<or> the child process continues.
-
-When both processes want to continue using libev, then this is usually the
-wrong result. In that case, usually one process (typically the parent) is
-supposed to continue with all watchers in place as before, while the other
-process typically wants to start fresh, i.e. without any active watchers.
-
-The cleanest and most efficient way to achieve that with libev is to
-simply create a new event loop, which of course will be "empty", and
-use that for new watchers. This has the advantage of not touching more
-memory than necessary, and thus avoiding the copy-on-write, and the
-disadvantage of having to use multiple event loops (which do not support
-signal watchers).
-
-When this is not possible, or you want to use the default loop for
-other reasons, then in the process that wants to start "fresh", call
-C<ev_loop_destroy (EV_DEFAULT)> followed by C<ev_default_loop (...)>.
-Destroying the default loop will "orphan" (not stop) all registered
-watchers, so you have to be careful not to execute code that modifies
-those watchers. Note also that in that case, you have to re-register any
-signal watchers.

-
-Cleanup watchers are called just before the event loop is being destroyed

-
-While there is no guarantee that the event loop gets destroyed, cleanup
-watchers provide a convenient method to install cleanup hooks for your
-program, worker threads and so on - you just to make sure to destroy the
-loop when you want them to be invoked.
-
-Cleanup watchers are invoked in the same way as any other watcher. Unlike
-all other watchers, they do not keep a reference to the event loop (which
-makes a lot of sense if you think about it). Like all other watchers, you
-can call libev functions in the callback, except C<ev_cleanup_start>.

-=head2 C<ev_async> - how to wake up an event loop
-
-In general, you cannot use an C<ev_loop> from multiple threads or other
-asynchronous sources such as signal handlers (as opposed to multiple event
-loops - those are of course safe to use in different threads).
-
-Sometimes, however, you need to wake up an event loop you do not control,
-for example because it belongs to another thread. This is what C<ev_async>
-watchers do: as long as the C<ev_async> watcher is active, you can signal
-it by calling C<ev_async_send>, which is thread- and signal safe.
-
-This functionality is very similar to C<ev_signal> watchers, as signals,
-too, are asynchronous in nature, and signals, too, will be compressed
-(i.e. the number of callback invocations may be less than the number of
-C<ev_async_send> calls). In fact, you could use signal watchers as a kind
-of "global async watchers" by using a watcher on an otherwise unused
-signal, and C<ev_feed_signal> to signal this watcher from another thread,
-even without knowing which loop owns the signal.
-
-=head3 Queueing
-
-C<ev_async> does not support queueing of data in any way. The reason
-is that the author does not know of a simple (or any) algorithm for a
-multiple-writer-single-reader queue that works in all cases and doesn't
-need elaborate support such as pthreads or unportable memory access
-semantics.
-
-That means that if you want to queue data, you have to provide your own
-queue. But at least I can tell you how to implement locking around your
-queue:
-
-=over 4
-
-=item queueing from a signal handler context
-
-To implement race-free queueing, you simply add to the queue in the signal
-handler but you block the signal handler in the watcher callback. Here is
-an example that does that for some fictitious SIGUSR1 handler:
-
- static ev_async mysig;
-
- static void
- sigusr1_handler (void)
- {
- sometype data;
-
- // no locking etc.
- queue_put (data);
- ev_async_send (EV_DEFAULT_ &mysig);
- }
-
- static void
- mysig_cb (EV_P_ ev_async *w, int revents)
- {
- sometype data;
- sigset_t block, prev;
-
- sigemptyset (&block);
- sigaddset (&block, SIGUSR1);
- sigprocmask (SIG_BLOCK, &block, &prev);
-
- while (queue_get (&data))
- process (data);
-
- if (sigismember (&prev, SIGUSR1)
- sigprocmask (SIG_UNBLOCK, &block, 0);
- }
-
-(Note: pthreads in theory requires you to use C<pthread_setmask>
-instead of C<sigprocmask> when you use threads, but libev doesn't do it
-either...).
-
-=item queueing from a thread context
-
-The strategy for threads is different, as you cannot (easily) block
-threads but you can easily preempt them, so to queue safely you need to
-employ a traditional mutex lock, such as in this pthread example:
-
- static ev_async mysig;
- static pthread_mutex_t mymutex = PTHREAD_MUTEX_INITIALIZER;
-
- static void
- otherthread (void)
- {
- // only need to lock the actual queueing operation
- pthread_mutex_lock (&mymutex);
- queue_put (data);
- pthread_mutex_unlock (&mymutex);
-
- ev_async_send (EV_DEFAULT_ &mysig);
- }
-
- static void
- mysig_cb (EV_P_ ev_async *w, int revents)
- {
- pthread_mutex_lock (&mymutex);
-
- while (queue_get (&data))
- process (data);
-
- pthread_mutex_unlock (&mymutex);
- }

-

-
-=item ev_async_init (ev_async *, callback)
-
-Initialises and configures the async watcher - it has no parameters of any
-kind. There is a C<ev_async_set> macro, but using it is utterly pointless,
-trust me.
-
-=item ev_async_send (loop, ev_async *)
-
-Sends/signals/activates the given C<ev_async> watcher, that is, feeds
-an C<EV_ASYNC> event on the watcher into the event loop, and instantly
-returns.
-
-Unlike C<ev_feed_event>, this call is safe to do from other threads,
-signal or similar contexts (see the discussion of C<EV_ATOMIC_T> in the
-embedding section below on what exactly this means).
-
-Note that, as with other watchers in libev, multiple events might get
-compressed into a single callback invocation (another way to look at
-this is that C<ev_async> watchers are level-triggered: they are set on
-C<ev_async_send>, reset when the event loop detects that).
-
-This call incurs the overhead of at most one extra system call per event
-loop iteration, if the event loop is blocked, and no syscall at all if
-the event loop (or your program) is processing events. That means that
-repeated calls are basically free (there is no need to avoid calls for
-performance reasons) and that the overhead becomes smaller (typically
-zero) under load.
-
-=item bool = ev_async_pending (ev_async *)
-
-Returns a non-zero value when C<ev_async_send> has been called on the
-watcher but the event has not yet been processed (or even noted) by the
-event loop.
-
-C<ev_async_send> sets a flag in the watcher and wakes up the loop. When
-the loop iterates next and checks for the watcher to have become active,
-it will reset the flag again. C<ev_async_pending> can be used to very
-quickly check whether invoking the loop might be a good idea.
-
-Not that this does I<not> check whether the watcher itself is pending,
-only whether it has been requested to make this watcher pending: there
-is a time window between the event loop checking and resetting the async
-notification, and the callback being invoked.

-
-=head1 OTHER FUNCTIONS
-
-There are some other functions of possible interest. Described. Here. Now.
-
-=over 4
-
-=item ev_once (loop, int fd, int events, ev_tstamp timeout, callback)
-
-This function combines a simple timer and an I/O watcher, calls your
-callback on whichever event happens first and automatically stops both
-watchers. This is useful if you want to wait for a single event on an fd
-or timeout without having to allocate/configure/start/stop/free one or
-more watchers yourself.
-
-If C<fd> is less than 0, then no I/O watcher will be started and the
-C<events> argument is being ignored. Otherwise, an C<ev_io> watcher for
-the given C<fd> and C<events> set will be created and started.
-
-If C<timeout> is less than 0, then no timeout watcher will be
-started. Otherwise an C<ev_timer> watcher with after = C<timeout> (and
-repeat = 0) will be started. C<0> is a valid timeout.
-
-The callback has the type C<void (*cb)(int revents, void *arg)> and is
-passed an C<revents> set like normal event callbacks (a combination of
-C<EV_ERROR>, C<EV_READ>, C<EV_WRITE> or C<EV_TIMER>) and the C<arg>
-value passed to C<ev_once>. Note that it is possible to receive I<both>
-a timeout and an io event at the same time - you probably should give io
-events precedence.
-
-Example: wait up to ten seconds for data to appear on STDIN_FILENO.
-
- static void stdin_ready (int revents, void *arg)
- {
- if (revents & EV_READ)
- /* stdin might have data for us, joy! */;
- else if (revents & EV_TIMER)
- /* doh, nothing entered */;
- }
-
- ev_once (STDIN_FILENO, EV_READ, 10., stdin_ready, 0);

-=item ev_feed_fd_event (loop, int fd, int revents)

-
-=head1 COMMON OR USEFUL IDIOMS (OR BOTH)
-
-This section explains some common idioms that are not immediately
-obvious. Note that examples are sprinkled over the whole manual, and this
-section only contains stuff that wouldn't fit anywhere else.
-
-=head2 ASSOCIATING CUSTOM DATA WITH A WATCHER
-
-Each watcher has, by default, a C<void *data> member that you can read
-or modify at any time: libev will completely ignore it. This can be used
-to associate arbitrary data with your watcher. If you need more data and
-don't want to allocate memory separately and store a pointer to it in that
-data member, you can also "subclass" the watcher type and provide your own
-data:
-
- struct my_io
- {
- ev_io io;
- int otherfd;
- void *somedata;
- struct whatever *mostinteresting;
- };
-
- ...
- struct my_io w;
- ev_io_init (&w.io, my_cb, fd, EV_READ);
-
-And since your callback will be called with a pointer to the watcher, you
-can cast it back to your own type:
-
- static void my_cb (struct ev_loop *loop, ev_io *w_, int revents)
- {
- struct my_io *w = (struct my_io *)w_;
- ...
- }
-
-More interesting and less C-conformant ways of casting your callback
-function type instead have been omitted.
-
-=head2 BUILDING YOUR OWN COMPOSITE WATCHERS
-
-Another common scenario is to use some data structure with multiple
-embedded watchers, in effect creating your own watcher that combines
-multiple libev event sources into one "super-watcher":
-
- struct my_biggy
- {
- int some_data;
- ev_timer t1;
- ev_timer t2;
- }
-
-In this case getting the pointer to C<my_biggy> is a bit more
-complicated: Either you store the address of your C<my_biggy> struct in
-the C<data> member of the watcher (for woozies or C++ coders), or you need
-to use some pointer arithmetic using C<offsetof> inside your watchers (for
-real programmers):
-
- #include <stddef.h>
-
- static void
- t1_cb (EV_P_ ev_timer *w, int revents)
- {
- struct my_biggy big = (struct my_biggy *)
- (((char *)w) - offsetof (struct my_biggy, t1));
- }
-
- static void
- t2_cb (EV_P_ ev_timer *w, int revents)
- {
- struct my_biggy big = (struct my_biggy *)
- (((char *)w) - offsetof (struct my_biggy, t2));
- }
-
-=head2 AVOIDING FINISHING BEFORE RETURNING
-
-Often you have structures like this in event-based programs:
-
- callback ()
- {
- free (request);
- }
-
- request = start_new_request (..., callback);
-
-The intent is to start some "lengthy" operation. The C<request> could be
-used to cancel the operation, or do other things with it.
-
-It's not uncommon to have code paths in C<start_new_request> that
-immediately invoke the callback, for example, to report errors. Or you add
-some caching layer that finds that it can skip the lengthy aspects of the
-operation and simply invoke the callback with the result.
-
-The problem here is that this will happen I<before> C<start_new_request>
-has returned, so C<request> is not set.
-
-Even if you pass the request by some safer means to the callback, you
-might want to do something to the request after starting it, such as
-canceling it, which probably isn't working so well when the callback has
-already been invoked.
-
-A common way around all these issues is to make sure that
-C<start_new_request> I<always> returns before the callback is invoked. If
-C<start_new_request> immediately knows the result, it can artificially
-delay invoking the callback by using a C<prepare> or C<idle> watcher for
-example, or more sneakily, by reusing an existing (stopped) watcher and
-pushing it into the pending queue:
-
- ev_set_cb (watcher, callback);
- ev_feed_event (EV_A_ watcher, 0);
-
-This way, C<start_new_request> can safely return before the callback is
-invoked, while not delaying callback invocation too much.
-
-=head2 MODEL/NESTED EVENT LOOP INVOCATIONS AND EXIT CONDITIONS
-
-Often (especially in GUI toolkits) there are places where you have
-I<modal> interaction, which is most easily implemented by recursively
-invoking C<ev_run>.
-
-This brings the problem of exiting - a callback might want to finish the
-main C<ev_run> call, but not the nested one (e.g. user clicked "Quit", but
-a modal "Are you sure?" dialog is still waiting), or just the nested one
-and not the main one (e.g. user clocked "Ok" in a modal dialog), or some
-other combination: In these cases, a simple C<ev_break> will not work.
-
-The solution is to maintain "break this loop" variable for each C<ev_run>
-invocation, and use a loop around C<ev_run> until the condition is
-triggered, using C<EVRUN_ONCE>:
-
- // main loop
- int exit_main_loop = 0;
-
- while (!exit_main_loop)
- ev_run (EV_DEFAULT_ EVRUN_ONCE);
-
- // in a modal watcher
- int exit_nested_loop = 0;
-
- while (!exit_nested_loop)
- ev_run (EV_A_ EVRUN_ONCE);
-
-To exit from any of these loops, just set the corresponding exit variable:
-
- // exit modal loop
- exit_nested_loop = 1;
-
- // exit main program, after modal loop is finished
- exit_main_loop = 1;
-
- // exit both
- exit_main_loop = exit_nested_loop = 1;
-
-=head2 THREAD LOCKING EXAMPLE
-
-Here is a fictitious example of how to run an event loop in a different
-thread from where callbacks are being invoked and watchers are
-created/added/removed.
-
-For a real-world example, see the C<EV::Loop::Async> perl module,
-which uses exactly this technique (which is suited for many high-level
-languages).
-
-The example uses a pthread mutex to protect the loop data, a condition
-variable to wait for callback invocations, an async watcher to notify the
-event loop thread and an unspecified mechanism to wake up the main thread.
-
-First, you need to associate some data with the event loop:
-
- typedef struct {
- mutex_t lock; /* global loop lock */
- ev_async async_w;
- thread_t tid;
- cond_t invoke_cv;
- } userdata;
-
- void prepare_loop (EV_P)
- {
- // for simplicity, we use a static userdata struct.
- static userdata u;
-
- ev_async_init (&u->async_w, async_cb);
- ev_async_start (EV_A_ &u->async_w);
-
- pthread_mutex_init (&u->lock, 0);
- pthread_cond_init (&u->invoke_cv, 0);
-
- // now associate this with the loop
- ev_set_userdata (EV_A_ u);
- ev_set_invoke_pending_cb (EV_A_ l_invoke);
- ev_set_loop_release_cb (EV_A_ l_release, l_acquire);
-
- // then create the thread running ev_run
- pthread_create (&u->tid, 0, l_run, EV_A);
- }
-
-The callback for the C<ev_async> watcher does nothing: the watcher is used
-solely to wake up the event loop so it takes notice of any new watchers
-that might have been added:
-
- static void
- async_cb (EV_P_ ev_async *w, int revents)
- {
- // just used for the side effects
- }
-
-The C<l_release> and C<l_acquire> callbacks simply unlock/lock the mutex
-protecting the loop data, respectively.
-
- static void
- l_release (EV_P)
- {
- userdata *u = ev_userdata (EV_A);
- pthread_mutex_unlock (&u->lock);
- }
-
- static void
- l_acquire (EV_P)
- {
- userdata *u = ev_userdata (EV_A);
- pthread_mutex_lock (&u->lock);
- }
-
-The event loop thread first acquires the mutex, and then jumps straight
-into C<ev_run>:
-
- void *
- l_run (void *thr_arg)
- {
- struct ev_loop *loop = (struct ev_loop *)thr_arg;
-
- l_acquire (EV_A);
- pthread_setcanceltype (PTHREAD_CANCEL_ASYNCHRONOUS, 0);
- ev_run (EV_A_ 0);
- l_release (EV_A);
-
- return 0;
- }
-
-Instead of invoking all pending watchers, the C<l_invoke> callback will
-signal the main thread via some unspecified mechanism (signals? pipe
-writes? C<Async::Interrupt>?) and then waits until all pending watchers
-have been called (in a while loop because a) spurious wakeups are possible
-and b) skipping inter-thread-communication when there are no pending
-watchers is very beneficial):
-
- static void
- l_invoke (EV_P)
- {
- userdata *u = ev_userdata (EV_A);
-
- while (ev_pending_count (EV_A))
- {
- wake_up_other_thread_in_some_magic_or_not_so_magic_way ();
- pthread_cond_wait (&u->invoke_cv, &u->lock);
- }
- }
-
-Now, whenever the main thread gets told to invoke pending watchers, it
-will grab the lock, call C<ev_invoke_pending> and then signal the loop
-thread to continue:
-
- static void
- real_invoke_pending (EV_P)
- {
- userdata *u = ev_userdata (EV_A);
-
- pthread_mutex_lock (&u->lock);
- ev_invoke_pending (EV_A);
- pthread_cond_signal (&u->invoke_cv);
- pthread_mutex_unlock (&u->lock);
- }
-
-Whenever you want to start/stop a watcher or do other modifications to an
-event loop, you will now have to lock:
-
- ev_timer timeout_watcher;
- userdata *u = ev_userdata (EV_A);
-
- ev_timer_init (&timeout_watcher, timeout_cb, 5.5, 0.);
-
- pthread_mutex_lock (&u->lock);
- ev_timer_start (EV_A_ &timeout_watcher);
- ev_async_send (EV_A_ &u->async_w);
- pthread_mutex_unlock (&u->lock);
-
-Note that sending the C<ev_async> watcher is required because otherwise
-an event loop currently blocking in the kernel will have no knowledge
-about the newly added timer. By waking up the loop it will pick up any new
-watchers in the next event loop iteration.
-
-=head2 THREADS, COROUTINES, CONTINUATIONS, QUEUES... INSTEAD OF CALLBACKS
-
-While the overhead of a callback that e.g. schedules a thread is small, it
-is still an overhead. If you embed libev, and your main usage is with some
-kind of threads or coroutines, you might want to customise libev so that
-doesn't need callbacks anymore.
-
-Imagine you have coroutines that you can switch to using a function
-C<switch_to (coro)>, that libev runs in a coroutine called C<libev_coro>
-and that due to some magic, the currently active coroutine is stored in a
-global called C<current_coro>. Then you can build your own "wait for libev
-event" primitive by changing C<EV_CB_DECLARE> and C<EV_CB_INVOKE> (note
-the differing C<;> conventions):
-
- #define EV_CB_DECLARE(type) struct my_coro *cb;
- #define EV_CB_INVOKE(watcher) switch_to ((watcher)->cb)
-
-That means instead of having a C callback function, you store the
-coroutine to switch to in each watcher, and instead of having libev call
-your callback, you instead have it switch to that coroutine.
-
-A coroutine might now wait for an event with a function called
-C<wait_for_event>. (the watcher needs to be started, as always, but it doesn't
-matter when, or whether the watcher is active or not when this function is
-called):
-
- void
- wait_for_event (ev_watcher *w)
- {
- ev_set_cb (w, current_coro);
- switch_to (libev_coro);
- }
-
-That basically suspends the coroutine inside C<wait_for_event> and
-continues the libev coroutine, which, when appropriate, switches back to
-this or any other coroutine.
-
-You can do similar tricks if you have, say, threads with an event queue -
-instead of storing a coroutine, you store the queue object and instead of
-switching to a coroutine, you push the watcher onto the queue and notify
-any waiters.
-
-To embed libev, see L</EMBEDDING>, but in short, it's easiest to create two
-files, F<my_ev.h> and F<my_ev.c> that include the respective libev files:
-
- // my_ev.h
- #define EV_CB_DECLARE(type) struct my_coro *cb;
- #define EV_CB_INVOKE(watcher) switch_to ((watcher)->cb);
- #include "../libev/ev.h"
-
- // my_ev.c
- #define EV_H "my_ev.h"
- #include "../libev/ev.c"
-
-And then use F<my_ev.h> when you would normally use F<ev.h>, and compile
-F<my_ev.c> into your project. When properly specifying include paths, you
-can even use F<ev.h> as header file name directly.
-
-
-=head1 LIBEVENT EMULATION
-
-Libev offers a compatibility emulation layer for libevent. It cannot
-emulate the internals of libevent, so here are some usage hints:
-
-=over 4
-
-=item * Only the libevent-1.4.1-beta API is being emulated.
-
-This was the newest libevent version available when libev was implemented,
-and is still mostly unchanged in 2010.
-
-=item * Use it by including <event.h>, as usual.
-
-=item * The following members are fully supported: ev_base, ev_callback,
-ev_arg, ev_fd, ev_res, ev_events.
-
-=item * Avoid using ev_flags and the EVLIST_*-macros, while it is
-maintained by libev, it does not work exactly the same way as in libevent (consider
-it a private API).
-
-=item * Priorities are not currently supported. Initialising priorities
-will fail and all watchers will have the same priority, even though there
-is an ev_pri field.
-
-=item * In libevent, the last base created gets the signals, in libev, the
-base that registered the signal gets the signals.
-
-=item * Other members are not supported.
-
-=item * The libev emulation is I<not> ABI compatible to libevent, you need
-to use the libev header file and library.

-
-=head1 C++ SUPPORT
-
-=head2 C API
-
-The normal C API should work fine when used from C++: both ev.h and the
-libev sources can be compiled as C++. Therefore, code that uses the C API
-will work fine.
-
-Proper exception specifications might have to be added to callbacks passed
-to libev: exceptions may be thrown only from watcher callbacks, all
-other callbacks (allocator, syserr, loop acquire/release and periodic
-reschedule callbacks) must not throw exceptions, and might need a C<throw
-()> specification. If you have code that needs to be compiled as both C
-and C++ you can use the C<EV_THROW> macro for this:
-
- static void
- fatal_error (const char *msg) EV_THROW
- {
- perror (msg);
- abort ();
- }
-
- ...
- ev_set_syserr_cb (fatal_error);
-
-The only API functions that can currently throw exceptions are C<ev_run>,
-C<ev_invoke>, C<ev_invoke_pending> and C<ev_loop_destroy> (the latter
-because it runs cleanup watchers).
-
-Throwing exceptions in watcher callbacks is only supported if libev itself
-is compiled with a C++ compiler or your C and C++ environments allow
-throwing exceptions through C libraries (most do).
-
-=head2 C++ API
-
-Libev comes with some simplistic wrapper classes for C++ that mainly allow
-you to use some convenience methods to start/stop watchers and also change
-the callback model to a model using method callbacks on objects.
-
-To use it,
-
- #include <ev++.h>
-
-This automatically includes F<ev.h> and puts all of its definitions (many
-of them macros) into the global namespace. All C++ specific things are
-put into the C<ev> namespace. It should support all the same embedding
-options as F<ev.h>, most notably C<EV_MULTIPLICITY>.
-
-Care has been taken to keep the overhead low. The only data member the C++
-classes add (compared to plain C-style watchers) is the event loop pointer
-that the watcher is associated with (or no additional members at all if
-you disable C<EV_MULTIPLICITY> when embedding libev).
-
-Currently, functions, static and non-static member functions and classes
-with C<operator ()> can be used as callbacks. Other types should be easy
-to add as long as they only need one additional pointer for context. If
-you need support for other types of functors please contact the author
-(preferably after implementing it).
-
-For all this to work, your C++ compiler either has to use the same calling
-conventions as your C compiler (for static member functions), or you have
-to embed libev and compile libev itself as C++.
-
-Here is a list of things available in the C<ev> namespace:
-
-=over 4
-
-=item C<ev::READ>, C<ev::WRITE> etc.
-
-These are just enum values with the same values as the C<EV_READ> etc.
-macros from F<ev.h>.
-
-=item C<ev::tstamp>, C<ev::now>
-
-Aliases to the same types/functions as with the C<ev_> prefix.
-
-=item C<ev::io>, C<ev::timer>, C<ev::periodic>, C<ev::idle>, C<ev::sig> etc.
-
-For each C<ev_TYPE> watcher in F<ev.h> there is a corresponding class of
-the same name in the C<ev> namespace, with the exception of C<ev_signal>
-which is called C<ev::sig> to avoid clashes with the C<signal> macro
-defined by many implementations.
-
-All of those classes have these methods:
-
-=over 4
-
-=item ev::TYPE::TYPE ()
-
-=item ev::TYPE::TYPE (loop)
-
-=item ev::TYPE::~TYPE
-
-The constructor (optionally) takes an event loop to associate the watcher
-with. If it is omitted, it will use C<EV_DEFAULT>.
-
-The constructor calls C<ev_init> for you, which means you have to call the
-C<set> method before starting it.
-
-It will not set a callback, however: You have to call the templated C<set>
-method to set a callback before you can start the watcher.
-
-(The reason why you have to use a method is a limitation in C++ which does
-not allow explicit template arguments for constructors).
-
-The destructor automatically stops the watcher if it is active.
-
-=item w->set<class, &class::method> (object *)
-
-This method sets the callback method to call. The method has to have a
-signature of C<void (*)(ev_TYPE &, int)>, it receives the watcher as
-first argument and the C<revents> as second. The object must be given as
-parameter and is stored in the C<data> member of the watcher.
-
-This method synthesizes efficient thunking code to call your method from
-the C callback that libev requires. If your compiler can inline your
-callback (i.e. it is visible to it at the place of the C<set> call and
-your compiler is good :), then the method will be fully inlined into the
-thunking function, making it as fast as a direct C callback.
-
-Example: simple class declaration and watcher initialisation
-
- struct myclass
- {
- void io_cb (ev::io &w, int revents) { }
- }
-
- myclass obj;
- ev::io iow;
- iow.set <myclass, &myclass::io_cb> (&obj);
-
-=item w->set (object *)
-
-This is a variation of a method callback - leaving out the method to call
-will default the method to C<operator ()>, which makes it possible to use
-functor objects without having to manually specify the C<operator ()> all
-the time. Incidentally, you can then also leave out the template argument
-list.
-
-The C<operator ()> method prototype must be C<void operator ()(watcher &w,
-int revents)>.
-
-See the method-C<set> above for more details.
-
-Example: use a functor object as callback.
-
- struct myfunctor
- {
- void operator() (ev::io &w, int revents)
- {
- ...
- }
- }
-
- myfunctor f;
-
- ev::io w;
- w.set (&f);
-
-=item w->set<function> (void *data = 0)
-
-Also sets a callback, but uses a static method or plain function as
-callback. The optional C<data> argument will be stored in the watcher's
-C<data> member and is free for you to use.
-
-The prototype of the C<function> must be C<void (*)(ev::TYPE &w, int)>.
-
-See the method-C<set> above for more details.
-
-Example: Use a plain function as callback.
-
- static void io_cb (ev::io &w, int revents) { }
- iow.set <io_cb> ();
-
-=item w->set (loop)
-
-Associates a different C<struct ev_loop> with this watcher. You can only
-do this when the watcher is inactive (and not pending either).
-
-=item w->set ([arguments])
-
-Basically the same as C<ev_TYPE_set> (except for C<ev::embed> watchers>),
-with the same arguments. Either this method or a suitable start method
-must be called at least once. Unlike the C counterpart, an active watcher
-gets automatically stopped and restarted when reconfiguring it with this
-method.
-
-For C<ev::embed> watchers this method is called C<set_embed>, to avoid
-clashing with the C<set (loop)> method.
-
-=item w->start ()
-
-Starts the watcher. Note that there is no C<loop> argument, as the
-constructor already stores the event loop.
-
-=item w->start ([arguments])
-
-Instead of calling C<set> and C<start> methods separately, it is often
-convenient to wrap them in one call. Uses the same type of arguments as
-the configure C<set> method of the watcher.
-
-=item w->stop ()
-
-Stops the watcher if it is active. Again, no C<loop> argument.
-
-=item w->again () (C<ev::timer>, C<ev::periodic> only)
-
-For C<ev::timer> and C<ev::periodic>, this invokes the corresponding
-C<ev_TYPE_again> function.
-
-=item w->sweep () (C<ev::embed> only)
-
-Invokes C<ev_embed_sweep>.
-
-=item w->update () (C<ev::stat> only)
-
-Invokes C<ev_stat_stat>.
-
-=back
-
-=back
-
-Example: Define a class with two I/O and idle watchers, start the I/O
-watchers in the constructor.
-
- class myclass
- {
- ev::io io ; void io_cb (ev::io &w, int revents);
- ev::io io2 ; void io2_cb (ev::io &w, int revents);
- ev::idle idle; void idle_cb (ev::idle &w, int revents);
-
- myclass (int fd)
- {
- io .set <myclass, &myclass::io_cb > (this);
- io2 .set <myclass, &myclass::io2_cb > (this);
- idle.set <myclass, &myclass::idle_cb> (this);
-
- io.set (fd, ev::WRITE); // configure the watcher
- io.start (); // start it whenever convenient
-
- io2.start (fd, ev::READ); // set + start in one call
- }
- };

-=head1 OTHER LANGUAGE BINDINGS
-
-Libev does not offer other language bindings itself, but bindings for a
-number of languages exist in the form of third-party packages. If you know
-any interesting language binding in addition to the ones listed here, drop
-me a note.
-
-=over 4
-
-=item Perl
-
-The EV module implements the full libev API and is actually used to test
-libev. EV is developed together with libev. Apart from the EV core module,
-there are additional modules that implement libev-compatible interfaces
-to C<libadns> (C<EV::ADNS>, but C<AnyEvent::DNS> is preferred nowadays),
-C<Net::SNMP> (C<Net::SNMP::EV>) and the C<libglib> event core (C<Glib::EV>
-and C<EV::Glib>).
-
-It can be found and installed via CPAN, its homepage is at
-L<http://software.schmorp.de/pkg/EV>.

-=item Python
-
-Python bindings can be found at L<http://code.google.com/p/pyev/>. It
-seems to be quite complete and well-documented.
-
-=item Ruby
-
-Tony Arcieri has written a ruby extension that offers access to a subset
-of the libev API and adds file handle abstractions, asynchronous DNS and

-
-Roger Pack reports that using the link order C<-lws2_32 -lmsvcrt-ruby-190>

-=item Javascript
-
-Node.js (L<http://nodejs.org>) uses libev as the underlying event library.
-
-=item Others

-There are others, and I stopped counting.
-
-=back
-
-
-=head1 MACRO MAGIC
-
-Libev can be compiled with a variety of options, the most fundamental
-of which is C<EV_MULTIPLICITY>. This option determines whether (most)
-functions and callbacks have an initial C<struct ev_loop *> argument.
-
-To make it easier to write programs that cope with either variant, the
-following macros are defined:
-
-=over 4
-
-=item C<EV_A>, C<EV_A_>
-
-This provides the loop I<argument> for functions, if one is required ("ev
-loop argument"). The C<EV_A> form is used when this is the sole argument,
-C<EV_A_> is used when other arguments are following. Example:
-
- ev_unref (EV_A);
- ev_timer_add (EV_A_ watcher);
- ev_run (EV_A_ 0);
-
-It assumes the variable C<loop> of type C<struct ev_loop *> is in scope,
-which is often provided by the following macro.
-
-=item C<EV_P>, C<EV_P_>
-
-This provides the loop I<parameter> for functions, if one is required ("ev
-loop parameter"). The C<EV_P> form is used when this is the sole parameter,
-C<EV_P_> is used when other parameters are following. Example:
-
- // this is how ev_unref is being declared
- static void ev_unref (EV_P);
-
- // this is how you can declare your typical callback
- static void cb (EV_P_ ev_timer *w, int revents)
-
-It declares a parameter C<loop> of type C<struct ev_loop *>, quite
-suitable for use with C<EV_A>.
-
-=item C<EV_DEFAULT>, C<EV_DEFAULT_>
-
-Similar to the other two macros, this gives you the value of the default
-loop, if multiple loops are supported ("ev loop default"). The default loop
-will be initialised if it isn't already initialised.
-
-For non-multiplicity builds, these macros do nothing, so you always have
-to initialise the loop somewhere.
-
-=item C<EV_DEFAULT_UC>, C<EV_DEFAULT_UC_>
-
-Usage identical to C<EV_DEFAULT> and C<EV_DEFAULT_>, but requires that the
-default loop has been initialised (C<UC> == unchecked). Their behaviour
-is undefined when the default loop has not been initialised by a previous
-execution of C<EV_DEFAULT>, C<EV_DEFAULT_> or C<ev_default_init (...)>.
-
-It is often prudent to use C<EV_DEFAULT> when initialising the first
-watcher in a function but use C<EV_DEFAULT_UC> afterwards.
-
-=back
-
-Example: Declare and initialise a check watcher, utilising the above
-macros so it will work regardless of whether multiple loops are supported
-or not.
-
- static void
- check_cb (EV_P_ ev_timer *w, int revents)
- {
- ev_check_stop (EV_A_ w);
- }
-
- ev_check check;
- ev_check_init (&check, check_cb);
- ev_check_start (EV_DEFAULT_ &check);
- ev_run (EV_DEFAULT_ 0);
-
-=head1 EMBEDDING
-
-Libev can (and often is) directly embedded into host
-applications. Examples of applications that embed it include the Deliantra
-Game Server, the EV perl module, the GNU Virtual Private Ethernet (gvpe)
-and rxvt-unicode.
-
-The goal is to enable you to just copy the necessary files into your
-source directory without having to change even a single line in them, so
-you can easily upgrade by simply copying (or having a checked-out copy of
-libev somewhere in your source tree).
-
-=head2 FILESETS
-
-Depending on what features you need you need to include one or more sets of files
-in your application.
-
-=head3 CORE EVENT LOOP
-
-To include only the libev core (all the C<ev_*> functions), with manual
-configuration (no autoconf):
-
- #define EV_STANDALONE 1
- #include "ev.c"
-
-This will automatically include F<ev.h>, too, and should be done in a
-single C source file only to provide the function implementations. To use
-it, do the same for F<ev.h> in all files wishing to use this API (best
-done by writing a wrapper around F<ev.h> that you can include instead and
-where you can put other configuration options):
-
- #define EV_STANDALONE 1
- #include "ev.h"
-
-Both header files and implementation files can be compiled with a C++
-compiler (at least, that's a stated goal, and breakage will be treated
-as a bug).
-
-You need the following files in your source tree, or in a directory
-in your include path (e.g. in libev/ when using -Ilibev):
-
- ev.h
- ev.c
- ev_vars.h
- ev_wrap.h
-
- ev_win32.c required on win32 platforms only
-
- ev_select.c only when select backend is enabled (which is enabled by default)
- ev_poll.c only when poll backend is enabled (disabled by default)
- ev_epoll.c only when the epoll backend is enabled (disabled by default)
- ev_kqueue.c only when the kqueue backend is enabled (disabled by default)
- ev_port.c only when the solaris port backend is enabled (disabled by default)
-
-F<ev.c> includes the backend files directly when enabled, so you only need
-to compile this single file.
-
-=head3 LIBEVENT COMPATIBILITY API
-
-To include the libevent compatibility API, also include:
-
- #include "event.c"
-
-in the file including F<ev.c>, and:
-
- #include "event.h"
-
-in the files that want to use the libevent API. This also includes F<ev.h>.
-
-You need the following additional files for this:
-
- event.h
- event.c
-
-=head3 AUTOCONF SUPPORT
-
-Instead of using C<EV_STANDALONE=1> and providing your configuration in
-whatever way you want, you can also C<m4_include([libev.m4])> in your
-F<configure.ac> and leave C<EV_STANDALONE> undefined. F<ev.c> will then
-include F<config.h> and configure itself accordingly.
-
-For this of course you need the m4 file:
-
- libev.m4
-
-=head2 PREPROCESSOR SYMBOLS/MACROS
-
-Libev can be configured via a variety of preprocessor symbols you have to
-define before including (or compiling) any of its files. The default in
-the absence of autoconf is documented for every option.
-
-Symbols marked with "(h)" do not change the ABI, and can have different
-values when compiling libev vs. including F<ev.h>, so it is permissible
-to redefine them before including F<ev.h> without breaking compatibility
-to a compiled library. All other symbols change the ABI, which means all
-users of libev and the libev code itself must be compiled with compatible
-settings.
-
-=over 4
-
-=item EV_COMPAT3 (h)
-
-Backwards compatibility is a major concern for libev. This is why this
-release of libev comes with wrappers for the functions and symbols that
-have been renamed between libev version 3 and 4.
-
-You can disable these wrappers (to test compatibility with future
-versions) by defining C<EV_COMPAT3> to C<0> when compiling your
-sources. This has the additional advantage that you can drop the C<struct>
-from C<struct ev_loop> declarations, as libev will provide an C<ev_loop>
-typedef in that case.
-
-In some future version, the default for C<EV_COMPAT3> will become C<0>,
-and in some even more future version the compatibility code will be
-removed completely.
-
-=item EV_STANDALONE (h)
-
-Must always be C<1> if you do not use autoconf configuration, which
-keeps libev from including F<config.h>, and it also defines dummy
-implementations for some libevent functions (such as logging, which is not
-supported). It will also not define any of the structs usually found in
-F<event.h> that are not directly supported by the libev core alone.
-
-In standalone mode, libev will still try to automatically deduce the
-configuration, but has to be more conservative.
-
-=item EV_USE_FLOOR
-
-If defined to be C<1>, libev will use the C<floor ()> function for its
-periodic reschedule calculations, otherwise libev will fall back on a
-portable (slower) implementation. If you enable this, you usually have to
-link against libm or something equivalent. Enabling this when the C<floor>
-function is not available will fail, so the safe default is to not enable
-this.
-
-=item EV_USE_MONOTONIC
-
-If defined to be C<1>, libev will try to detect the availability of the
-monotonic clock option at both compile time and runtime. Otherwise no
-use of the monotonic clock option will be attempted. If you enable this,
-you usually have to link against librt or something similar. Enabling it
-when the functionality isn't available is safe, though, although you have
-to make sure you link against any libraries where the C<clock_gettime>
-function is hiding in (often F<-lrt>). See also C<EV_USE_CLOCK_SYSCALL>.
-
-=item EV_USE_REALTIME
-
-If defined to be C<1>, libev will try to detect the availability of the
-real-time clock option at compile time (and assume its availability
-at runtime if successful). Otherwise no use of the real-time clock
-option will be attempted. This effectively replaces C<gettimeofday>
-by C<clock_get (CLOCK_REALTIME, ...)> and will not normally affect
-correctness. See the note about libraries in the description of
-C<EV_USE_MONOTONIC>, though. Defaults to the opposite value of
-C<EV_USE_CLOCK_SYSCALL>.
-
-=item EV_USE_CLOCK_SYSCALL
-
-If defined to be C<1>, libev will try to use a direct syscall instead
-of calling the system-provided C<clock_gettime> function. This option
-exists because on GNU/Linux, C<clock_gettime> is in C<librt>, but C<librt>
-unconditionally pulls in C<libpthread>, slowing down single-threaded
-programs needlessly. Using a direct syscall is slightly slower (in
-theory), because no optimised vdso implementation can be used, but avoids
-the pthread dependency. Defaults to C<1> on GNU/Linux with glibc 2.x or
-higher, as it simplifies linking (no need for C<-lrt>).
-
-=item EV_USE_NANOSLEEP
-
-If defined to be C<1>, libev will assume that C<nanosleep ()> is available
-and will use it for delays. Otherwise it will use C<select ()>.
-
-=item EV_USE_EVENTFD
-
-If defined to be C<1>, then libev will assume that C<eventfd ()> is
-available and will probe for kernel support at runtime. This will improve
-C<ev_signal> and C<ev_async> performance and reduce resource consumption.
-If undefined, it will be enabled if the headers indicate GNU/Linux + Glibc
-2.7 or newer, otherwise disabled.
-
-=item EV_USE_SELECT
-
-If undefined or defined to be C<1>, libev will compile in support for the
-C<select>(2) backend. No attempt at auto-detection will be done: if no
-other method takes over, select will be it. Otherwise the select backend
-will not be compiled in.
-
-=item EV_SELECT_USE_FD_SET
-
-If defined to C<1>, then the select backend will use the system C<fd_set>
-structure. This is useful if libev doesn't compile due to a missing
-C<NFDBITS> or C<fd_mask> definition or it mis-guesses the bitset layout
-on exotic systems. This usually limits the range of file descriptors to
-some low limit such as 1024 or might have other limitations (winsocket
-only allows 64 sockets). The C<FD_SETSIZE> macro, set before compilation,
-configures the maximum size of the C<fd_set>.
-
-=item EV_SELECT_IS_WINSOCKET
-
-When defined to C<1>, the select backend will assume that
-select/socket/connect etc. don't understand file descriptors but
-wants osf handles on win32 (this is the case when the select to
-be used is the winsock select). This means that it will call
-C<_get_osfhandle> on the fd to convert it to an OS handle. Otherwise,
-it is assumed that all these functions actually work on fds, even
-on win32. Should not be defined on non-win32 platforms.
-
-=item EV_FD_TO_WIN32_HANDLE(fd)
-
-If C<EV_SELECT_IS_WINSOCKET> is enabled, then libev needs a way to map
-file descriptors to socket handles. When not defining this symbol (the
-default), then libev will call C<_get_osfhandle>, which is usually
-correct. In some cases, programs use their own file descriptor management,
-in which case they can provide this function to map fds to socket handles.
-
-=item EV_WIN32_HANDLE_TO_FD(handle)
-
-If C<EV_SELECT_IS_WINSOCKET> then libev maps handles to file descriptors
-using the standard C<_open_osfhandle> function. For programs implementing
-their own fd to handle mapping, overwriting this function makes it easier
-to do so. This can be done by defining this macro to an appropriate value.
-
-=item EV_WIN32_CLOSE_FD(fd)
-
-If programs implement their own fd to handle mapping on win32, then this
-macro can be used to override the C<close> function, useful to unregister
-file descriptors again. Note that the replacement function has to close
-the underlying OS handle.
-
-=item EV_USE_WSASOCKET
-
-If defined to be C<1>, libev will use C<WSASocket> to create its internal
-communication socket, which works better in some environments. Otherwise,
-the normal C<socket> function will be used, which works better in other
-environments.
-
-=item EV_USE_POLL
-
-If defined to be C<1>, libev will compile in support for the C<poll>(2)
-backend. Otherwise it will be enabled on non-win32 platforms. It
-takes precedence over select.
-
-=item EV_USE_EPOLL
-
-If defined to be C<1>, libev will compile in support for the Linux
-C<epoll>(7) backend. Its availability will be detected at runtime,
-otherwise another method will be used as fallback. This is the preferred
-backend for GNU/Linux systems. If undefined, it will be enabled if the
-headers indicate GNU/Linux + Glibc 2.4 or newer, otherwise disabled.
-
-=item EV_USE_KQUEUE
-
-If defined to be C<1>, libev will compile in support for the BSD style
-C<kqueue>(2) backend. Its actual availability will be detected at runtime,
-otherwise another method will be used as fallback. This is the preferred
-backend for BSD and BSD-like systems, although on most BSDs kqueue only
-supports some types of fds correctly (the only platform we found that
-supports ptys for example was NetBSD), so kqueue might be compiled in, but
-not be used unless explicitly requested. The best way to use it is to find
-out whether kqueue supports your type of fd properly and use an embedded
-kqueue loop.
-
-=item EV_USE_PORT
-
-If defined to be C<1>, libev will compile in support for the Solaris
-10 port style backend. Its availability will be detected at runtime,
-otherwise another method will be used as fallback. This is the preferred
-backend for Solaris 10 systems.
-
-=item EV_USE_DEVPOLL
-
-Reserved for future expansion, works like the USE symbols above.
-
-=item EV_USE_INOTIFY
-
-If defined to be C<1>, libev will compile in support for the Linux inotify
-interface to speed up C<ev_stat> watchers. Its actual availability will
-be detected at runtime. If undefined, it will be enabled if the headers
-indicate GNU/Linux + Glibc 2.4 or newer, otherwise disabled.
-
-=item EV_NO_SMP
-
-If defined to be C<1>, libev will assume that memory is always coherent
-between threads, that is, threads can be used, but threads never run on
-different cpus (or different cpu cores). This reduces dependencies
-and makes libev faster.
-
-=item EV_NO_THREADS
-
-If defined to be C<1>, libev will assume that it will never be called from
-different threads (that includes signal handlers), which is a stronger
-assumption than C<EV_NO_SMP>, above. This reduces dependencies and makes
-libev faster.
-
-=item EV_ATOMIC_T
-
-Libev requires an integer type (suitable for storing C<0> or C<1>) whose
-access is atomic with respect to other threads or signal contexts. No
-such type is easily found in the C language, so you can provide your own
-type that you know is safe for your purposes. It is used both for signal
-handler "locking" as well as for signal and thread safety in C<ev_async>
-watchers.
-
-In the absence of this define, libev will use C<sig_atomic_t volatile>
-(from F<signal.h>), which is usually good enough on most platforms.
-
-=item EV_H (h)
-
-The name of the F<ev.h> header file used to include it. The default if
-undefined is C<"ev.h"> in F<event.h>, F<ev.c> and F<ev++.h>. This can be
-used to virtually rename the F<ev.h> header file in case of conflicts.
-
-=item EV_CONFIG_H (h)
-
-If C<EV_STANDALONE> isn't C<1>, this variable can be used to override
-F<ev.c>'s idea of where to find the F<config.h> file, similarly to
-C<EV_H>, above.
-
-=item EV_EVENT_H (h)
-
-Similarly to C<EV_H>, this macro can be used to override F<event.c>'s idea
-of how the F<event.h> header can be found, the default is C<"event.h">.
-
-=item EV_PROTOTYPES (h)
-
-If defined to be C<0>, then F<ev.h> will not define any function
-prototypes, but still define all the structs and other symbols. This is
-occasionally useful if you want to provide your own wrapper functions
-around libev functions.
-
-=item EV_MULTIPLICITY
-
-If undefined or defined to C<1>, then all event-loop-specific functions
-will have the C<struct ev_loop *> as first argument, and you can create
-additional independent event loops. Otherwise there will be no support
-for multiple event loops and there is no first event loop pointer
-argument. Instead, all functions act on the single default loop.
-
-Note that C<EV_DEFAULT> and C<EV_DEFAULT_> will no longer provide a
-default loop when multiplicity is switched off - you always have to
-initialise the loop manually in this case.
-
-=item EV_MINPRI
-
-=item EV_MAXPRI
-
-The range of allowed priorities. C<EV_MINPRI> must be smaller or equal to
-C<EV_MAXPRI>, but otherwise there are no non-obvious limitations. You can
-provide for more priorities by overriding those symbols (usually defined
-to be C<-2> and C<2>, respectively).
-
-When doing priority-based operations, libev usually has to linearly search
-all the priorities, so having many of them (hundreds) uses a lot of space
-and time, so using the defaults of five priorities (-2 .. +2) is usually
-fine.
-
-If your embedding application does not need any priorities, defining these
-both to C<0> will save some memory and CPU.
-
-=item EV_PERIODIC_ENABLE, EV_IDLE_ENABLE, EV_EMBED_ENABLE, EV_STAT_ENABLE,
-EV_PREPARE_ENABLE, EV_CHECK_ENABLE, EV_FORK_ENABLE, EV_SIGNAL_ENABLE,
-EV_ASYNC_ENABLE, EV_CHILD_ENABLE.
-
-If undefined or defined to be C<1> (and the platform supports it), then
-the respective watcher type is supported. If defined to be C<0>, then it
-is not. Disabling watcher types mainly saves code size.
-
-=item EV_FEATURES
-
-If you need to shave off some kilobytes of code at the expense of some
-speed (but with the full API), you can define this symbol to request
-certain subsets of functionality. The default is to enable all features
-that can be enabled on the platform.
-
-A typical way to use this symbol is to define it to C<0> (or to a bitset
-with some broad features you want) and then selectively re-enable
-additional parts you want, for example if you want everything minimal,
-but multiple event loop support, async and child watchers and the poll
-backend, use this:
-
- #define EV_FEATURES 0
- #define EV_MULTIPLICITY 1
- #define EV_USE_POLL 1
- #define EV_CHILD_ENABLE 1
- #define EV_ASYNC_ENABLE 1
-
-The actual value is a bitset, it can be a combination of the following
-values (by default, all of these are enabled):
-
-=over 4
-
-=item C<1> - faster/larger code
-
-Use larger code to speed up some operations.
-
-Currently this is used to override some inlining decisions (enlarging the
-code size by roughly 30% on amd64).
-
-When optimising for size, use of compiler flags such as C<-Os> with
-gcc is recommended, as well as C<-DNDEBUG>, as libev contains a number of
-assertions.
-
-The default is off when C<__OPTIMIZE_SIZE__> is defined by your compiler
-(e.g. gcc with C<-Os>).
-
-=item C<2> - faster/larger data structures
-
-Replaces the small 2-heap for timer management by a faster 4-heap, larger
-hash table sizes and so on. This will usually further increase code size
-and can additionally have an effect on the size of data structures at
-runtime.
-
-The default is off when C<__OPTIMIZE_SIZE__> is defined by your compiler
-(e.g. gcc with C<-Os>).
-
-=item C<4> - full API configuration
-
-This enables priorities (sets C<EV_MAXPRI>=2 and C<EV_MINPRI>=-2), and
-enables multiplicity (C<EV_MULTIPLICITY>=1).
-
-=item C<8> - full API
-
-This enables a lot of the "lesser used" API functions. See C<ev.h> for
-details on which parts of the API are still available without this
-feature, and do not complain if this subset changes over time.
-
-=item C<16> - enable all optional watcher types
-
-Enables all optional watcher types. If you want to selectively enable
-only some watcher types other than I/O and timers (e.g. prepare,
-embed, async, child...) you can enable them manually by defining
-C<EV_watchertype_ENABLE> to C<1> instead.
-
-=item C<32> - enable all backends
-
-This enables all backends - without this feature, you need to enable at
-least one backend manually (C<EV_USE_SELECT> is a good choice).
-
-=item C<64> - enable OS-specific "helper" APIs
-
-Enable inotify, eventfd, signalfd and similar OS-specific helper APIs by
-default.
-
-=back
-
-Compiling with C<gcc -Os -DEV_STANDALONE -DEV_USE_EPOLL=1 -DEV_FEATURES=0>
-reduces the compiled size of libev from 24.7Kb code/2.8Kb data to 6.5Kb
-code/0.3Kb data on my GNU/Linux amd64 system, while still giving you I/O
-watchers, timers and monotonic clock support.
-
-With an intelligent-enough linker (gcc+binutils are intelligent enough
-when you use C<-Wl,--gc-sections -ffunction-sections>) functions unused by
-your program might be left out as well - a binary starting a timer and an
-I/O watcher then might come out at only 5Kb.
-
-=item EV_API_STATIC
-
-If this symbol is defined (by default it is not), then all identifiers
-will have static linkage. This means that libev will not export any
-identifiers, and you cannot link against libev anymore. This can be useful
-when you embed libev, only want to use libev functions in a single file,
-and do not want its identifiers to be visible.
-
-To use this, define C<EV_API_STATIC> and include F<ev.c> in the file that
-wants to use libev.
-
-This option only works when libev is compiled with a C compiler, as C++
-doesn't support the required declaration syntax.
-
-=item EV_AVOID_STDIO
-
-If this is set to C<1> at compiletime, then libev will avoid using stdio
-functions (printf, scanf, perror etc.). This will increase the code size
-somewhat, but if your program doesn't otherwise depend on stdio and your
-libc allows it, this avoids linking in the stdio library which is quite
-big.
-
-Note that error messages might become less precise when this option is
-enabled.
-
-=item EV_NSIG
-
-The highest supported signal number, +1 (or, the number of
-signals): Normally, libev tries to deduce the maximum number of signals
-automatically, but sometimes this fails, in which case it can be
-specified. Also, using a lower number than detected (C<32> should be
-good for about any system in existence) can save some memory, as libev
-statically allocates some 12-24 bytes per signal number.
-
-=item EV_PID_HASHSIZE
-
-C<ev_child> watchers use a small hash table to distribute workload by
-pid. The default size is C<16> (or C<1> with C<EV_FEATURES> disabled),
-usually more than enough. If you need to manage thousands of children you
-might want to increase this value (I<must> be a power of two).
-
-=item EV_INOTIFY_HASHSIZE
-
-C<ev_stat> watchers use a small hash table to distribute workload by
-inotify watch id. The default size is C<16> (or C<1> with C<EV_FEATURES>
-disabled), usually more than enough. If you need to manage thousands of
-C<ev_stat> watchers you might want to increase this value (I<must> be a
-power of two).
-
-=item EV_USE_4HEAP
-
-Heaps are not very cache-efficient. To improve the cache-efficiency of the
-timer and periodics heaps, libev uses a 4-heap when this symbol is defined
-to C<1>. The 4-heap uses more complicated (longer) code but has noticeably
-faster performance with many (thousands) of watchers.
-
-The default is C<1>, unless C<EV_FEATURES> overrides it, in which case it
-will be C<0>.
-
-=item EV_HEAP_CACHE_AT
-
-Heaps are not very cache-efficient. To improve the cache-efficiency of the
-timer and periodics heaps, libev can cache the timestamp (I<at>) within
-the heap structure (selected by defining C<EV_HEAP_CACHE_AT> to C<1>),
-which uses 8-12 bytes more per watcher and a few hundred bytes more code,
-but avoids random read accesses on heap changes. This improves performance
-noticeably with many (hundreds) of watchers.
-
-The default is C<1>, unless C<EV_FEATURES> overrides it, in which case it
-will be C<0>.
-
-=item EV_VERIFY
-
-Controls how much internal verification (see C<ev_verify ()>) will
-be done: If set to C<0>, no internal verification code will be compiled
-in. If set to C<1>, then verification code will be compiled in, but not
-called. If set to C<2>, then the internal verification code will be
-called once per loop, which can slow down libev. If set to C<3>, then the
-verification code will be called very frequently, which will slow down
-libev considerably.
-
-The default is C<1>, unless C<EV_FEATURES> overrides it, in which case it
-will be C<0>.
-
-=item EV_COMMON
-
-By default, all watchers have a C<void *data> member. By redefining
-this macro to something else you can include more and other types of
-members. You have to define it each time you include one of the files,
-though, and it must be identical each time.
-
-For example, the perl EV module uses something like this:
-
- #define EV_COMMON \
- SV *self; /* contains this struct */ \
- SV *cb_sv, *fh /* note no trailing ";" */
-
-=item EV_CB_DECLARE (type)
-
-=item EV_CB_INVOKE (watcher, revents)
-
-=item ev_set_cb (ev, cb)
-
-Can be used to change the callback member declaration in each watcher,
-and the way callbacks are invoked and set. Must expand to a struct member
-definition and a statement, respectively. See the F<ev.h> header file for
-their default definitions. One possible use for overriding these is to
-avoid the C<struct ev_loop *> as first argument in all cases, or to use
-method calls instead of plain function calls in C++.
-
-=back
-
-=head2 EXPORTED API SYMBOLS
-
-If you need to re-export the API (e.g. via a DLL) and you need a list of
-exported symbols, you can use the provided F<Symbol.*> files which list
-all public symbols, one per line:
-
- Symbols.ev for libev proper
- Symbols.event for the libevent emulation
-
-This can also be used to rename all public symbols to avoid clashes with
-multiple versions of libev linked together (which is obviously bad in
-itself, but sometimes it is inconvenient to avoid this).
-
-A sed command like this will create wrapper C<#define>'s that you need to
-include before including F<ev.h>:
-
- <Symbols.ev sed -e "s/.*/#define & myprefix_&/" >wrap.h
-
-This would create a file F<wrap.h> which essentially looks like this:
-
- #define ev_backend myprefix_ev_backend
- #define ev_check_start myprefix_ev_check_start
- #define ev_check_stop myprefix_ev_check_stop
- ...
-
-=head2 EXAMPLES
-
-For a real-world example of a program the includes libev
-verbatim, you can have a look at the EV perl module
-(L<http://software.schmorp.de/pkg/EV.html>). It has the libev files in
-the F<libev/> subdirectory and includes them in the F<EV/EVAPI.h> (public
-interface) and F<EV.xs> (implementation) files. Only the F<EV.xs> file
-will be compiled. It is pretty complex because it provides its own header
-file.
-
-The usage in rxvt-unicode is simpler. It has a F<ev_cpp.h> header file
-that everybody includes and which overrides some configure choices:
-
- #define EV_FEATURES 8
- #define EV_USE_SELECT 1
- #define EV_PREPARE_ENABLE 1
- #define EV_IDLE_ENABLE 1
- #define EV_SIGNAL_ENABLE 1
- #define EV_CHILD_ENABLE 1
- #define EV_USE_STDEXCEPT 0
- #define EV_CONFIG_H <config.h>
-
- #include "ev++.h"
-
-And a F<ev_cpp.C> implementation file that contains libev proper and is compiled:
-
- #include "ev_cpp.h"
- #include "ev.c"
-
-=head1 INTERACTION WITH OTHER PROGRAMS, LIBRARIES OR THE ENVIRONMENT
-
-=head2 THREADS AND COROUTINES
-
-=head3 THREADS
-
-All libev functions are reentrant and thread-safe unless explicitly
-documented otherwise, but libev implements no locking itself. This means
-that you can use as many loops as you want in parallel, as long as there
-are no concurrent calls into any libev function with the same loop
-parameter (C<ev_default_*> calls have an implicit default loop parameter,
-of course): libev guarantees that different event loops share no data
-structures that need any locking.
-
-Or to put it differently: calls with different loop parameters can be done
-concurrently from multiple threads, calls with the same loop parameter
-must be done serially (but can be done from different threads, as long as
-only one thread ever is inside a call at any point in time, e.g. by using
-a mutex per loop).
-
-Specifically to support threads (and signal handlers), libev implements
-so-called C<ev_async> watchers, which allow some limited form of
-concurrency on the same event loop, namely waking it up "from the
-outside".
-
-If you want to know which design (one loop, locking, or multiple loops
-without or something else still) is best for your problem, then I cannot
-help you, but here is some generic advice:
-
-=over 4
-
-=item * most applications have a main thread: use the default libev loop
-in that thread, or create a separate thread running only the default loop.
-
-This helps integrating other libraries or software modules that use libev
-themselves and don't care/know about threading.
-
-=item * one loop per thread is usually a good model.
-
-Doing this is almost never wrong, sometimes a better-performance model
-exists, but it is always a good start.
-
-=item * other models exist, such as the leader/follower pattern, where one
-loop is handed through multiple threads in a kind of round-robin fashion.
-
-Choosing a model is hard - look around, learn, know that usually you can do
-better than you currently do :-)
-
-=item * often you need to talk to some other thread which blocks in the
-event loop.
-
-C<ev_async> watchers can be used to wake them up from other threads safely
-(or from signal contexts...).
-
-An example use would be to communicate signals or other events that only
-work in the default loop by registering the signal watcher with the
-default loop and triggering an C<ev_async> watcher from the default loop
-watcher callback into the event loop interested in the signal.
-
-=back
-
-See also L</THREAD LOCKING EXAMPLE>.
-
-=head3 COROUTINES
-
-Libev is very accommodating to coroutines ("cooperative threads"):
-libev fully supports nesting calls to its functions from different
-coroutines (e.g. you can call C<ev_run> on the same loop from two
-different coroutines, and switch freely between both coroutines running
-the loop, as long as you don't confuse yourself). The only exception is
-that you must not do this from C<ev_periodic> reschedule callbacks.
-
-Care has been taken to ensure that libev does not keep local state inside
-C<ev_run>, and other calls do not usually allow for coroutine switches as
-they do not call any callbacks.
-
-=head2 COMPILER WARNINGS
-
-Depending on your compiler and compiler settings, you might get no or a
-lot of warnings when compiling libev code. Some people are apparently
-scared by this.
-
-However, these are unavoidable for many reasons. For one, each compiler
-has different warnings, and each user has different tastes regarding
-warning options. "Warn-free" code therefore cannot be a goal except when
-targeting a specific compiler and compiler-version.
-
-Another reason is that some compiler warnings require elaborate
-workarounds, or other changes to the code that make it less clear and less
-maintainable.
-
-And of course, some compiler warnings are just plain stupid, or simply
-wrong (because they don't actually warn about the condition their message
-seems to warn about). For example, certain older gcc versions had some
-warnings that resulted in an extreme number of false positives. These have
-been fixed, but some people still insist on making code warn-free with
-such buggy versions.
-
-While libev is written to generate as few warnings as possible,
-"warn-free" code is not a goal, and it is recommended not to build libev
-with any compiler warnings enabled unless you are prepared to cope with
-them (e.g. by ignoring them). Remember that warnings are just that:
-warnings, not errors, or proof of bugs.
-
-
-=head2 VALGRIND
-
-Valgrind has a special section here because it is a popular tool that is
-highly useful. Unfortunately, valgrind reports are very hard to interpret.
-
-If you think you found a bug (memory leak, uninitialised data access etc.)
-in libev, then check twice: If valgrind reports something like:
-
- ==2274== definitely lost: 0 bytes in 0 blocks.
- ==2274== possibly lost: 0 bytes in 0 blocks.
- ==2274== still reachable: 256 bytes in 1 blocks.
-
-Then there is no memory leak, just as memory accounted to global variables
-is not a memleak - the memory is still being referenced, and didn't leak.
-
-Similarly, under some circumstances, valgrind might report kernel bugs
-as if it were a bug in libev (e.g. in realloc or in the poll backend,
-although an acceptable workaround has been found here), or it might be
-confused.
-
-Keep in mind that valgrind is a very good tool, but only a tool. Don't
-make it into some kind of religion.
-
-If you are unsure about something, feel free to contact the mailing list
-with the full valgrind report and an explanation on why you think this
-is a bug in libev (best check the archives, too :). However, don't be
-annoyed when you get a brisk "this is no bug" answer and take the chance
-of learning how to interpret valgrind properly.
-
-If you need, for some reason, empty reports from valgrind for your project
-I suggest using suppression lists.

-=head1 PORTABILITY NOTES
-
-=head2 GNU/LINUX 32 BIT LIMITATIONS
-
-GNU/Linux is the only common platform that supports 64 bit file/large file
-interfaces but I<disables> them by default.
-
-That means that libev compiled in the default environment doesn't support
-files larger than 2GiB or so, which mainly affects C<ev_stat> watchers.
-
-Unfortunately, many programs try to work around this GNU/Linux issue
-by enabling the large file API, which makes them incompatible with the
-standard libev compiled for their system.
-
-Likewise, libev cannot enable the large file API itself as this would
-suddenly make it incompatible to the default compile time environment,
-i.e. all programs not using special compile switches.
-
-=head2 OS/X AND DARWIN BUGS
-
-The whole thing is a bug if you ask me - basically any system interface
-you touch is broken, whether it is locales, poll, kqueue or even the
-OpenGL drivers.
-
-=head3 C<kqueue> is buggy
-
-The kqueue syscall is broken in all known versions - most versions support
-only sockets, many support pipes.
-
-Libev tries to work around this by not using C<kqueue> by default on this
-rotten platform, but of course you can still ask for it when creating a
-loop - embedding a socket-only kqueue loop into a select-based one is
-probably going to work well.
-
-=head3 C<poll> is buggy
-
-Instead of fixing C<kqueue>, Apple replaced their (working) C<poll>
-implementation by something calling C<kqueue> internally around the 10.5.6
-release, so now C<kqueue> I<and> C<poll> are broken.
-
-Libev tries to work around this by not using C<poll> by default on
-this rotten platform, but of course you can still ask for it when creating
-a loop.
-
-=head3 C<select> is buggy
-
-All that's left is C<select>, and of course Apple found a way to fuck this
-one up as well: On OS/X, C<select> actively limits the number of file
-descriptors you can pass in to 1024 - your program suddenly crashes when
-you use more.
-
-There is an undocumented "workaround" for this - defining
-C<_DARWIN_UNLIMITED_SELECT>, which libev tries to use, so select I<should>
-work on OS/X.
-
-=head2 SOLARIS PROBLEMS AND WORKAROUNDS
-
-=head3 C<errno> reentrancy
-
-The default compile environment on Solaris is unfortunately so
-thread-unsafe that you can't even use components/libraries compiled
-without C<-D_REENTRANT> in a threaded program, which, of course, isn't
-defined by default. A valid, if stupid, implementation choice.
-
-If you want to use libev in threaded environments you have to make sure
-it's compiled with C<_REENTRANT> defined.
-
-=head3 Event port backend
-
-The scalable event interface for Solaris is called "event
-ports". Unfortunately, this mechanism is very buggy in all major
-releases. If you run into high CPU usage, your program freezes or you get
-a large number of spurious wakeups, make sure you have all the relevant
-and latest kernel patches applied. No, I don't know which ones, but there
-are multiple ones to apply, and afterwards, event ports actually work
-great.
-
-If you can't get it to work, you can try running the program by setting
-the environment variable C<LIBEV_FLAGS=3> to only allow C<poll> and
-C<select> backends.
-
-=head2 AIX POLL BUG
-
-AIX unfortunately has a broken C<poll.h> header. Libev works around
-this by trying to avoid the poll backend altogether (i.e. it's not even
-compiled in), which normally isn't a big problem as C<select> works fine
-with large bitsets on AIX, and AIX is dead anyway.
-
-=head2 WIN32 PLATFORM LIMITATIONS AND WORKAROUNDS
-
-=head3 General issues
-
-Win32 doesn't support any of the standards (e.g. POSIX) that libev
-requires, and its I/O model is fundamentally incompatible with the POSIX
-model. Libev still offers limited functionality on this platform in
-the form of the C<EVBACKEND_SELECT> backend, and only supports socket
-descriptors. This only applies when using Win32 natively, not when using
-e.g. cygwin. Actually, it only applies to the microsofts own compilers,
-as every compiler comes with a slightly differently broken/incompatible
-environment.
-
-Lifting these limitations would basically require the full
-re-implementation of the I/O system. If you are into this kind of thing,
-then note that glib does exactly that for you in a very portable way (note
-also that glib is the slowest event library known to man).
-
-There is no supported compilation method available on windows except
-embedding it into other applications.
-
-Sensible signal handling is officially unsupported by Microsoft - libev
-tries its best, but under most conditions, signals will simply not work.
-
-Not a libev limitation but worth mentioning: windows apparently doesn't
-accept large writes: instead of resulting in a partial write, windows will
-either accept everything or return C<ENOBUFS> if the buffer is too large,
-so make sure you only write small amounts into your sockets (less than a
-megabyte seems safe, but this apparently depends on the amount of memory
-available).
-
-Due to the many, low, and arbitrary limits on the win32 platform and
-the abysmal performance of winsockets, using a large number of sockets
-is not recommended (and not reasonable). If your program needs to use
-more than a hundred or so sockets, then likely it needs to use a totally
-different implementation for windows, as libev offers the POSIX readiness
-notification model, which cannot be implemented efficiently on windows
-(due to Microsoft monopoly games).
-
-A typical way to use libev under windows is to embed it (see the embedding
-section for details) and use the following F<evwrap.h> header file instead
-of F<ev.h>:
-
- #define EV_STANDALONE /* keeps ev from requiring config.h */
- #define EV_SELECT_IS_WINSOCKET 1 /* configure libev for windows select */
-
- #include "ev.h"
-
-And compile the following F<evwrap.c> file into your project (make sure
-you do I<not> compile the F<ev.c> or any other embedded source files!):
-
- #include "evwrap.h"
- #include "ev.c"
-
-=head3 The winsocket C<select> function
-
-The winsocket C<select> function doesn't follow POSIX in that it
-requires socket I<handles> and not socket I<file descriptors> (it is
-also extremely buggy). This makes select very inefficient, and also
-requires a mapping from file descriptors to socket handles (the Microsoft
-C runtime provides the function C<_open_osfhandle> for this). See the
-discussion of the C<EV_SELECT_USE_FD_SET>, C<EV_SELECT_IS_WINSOCKET> and
-C<EV_FD_TO_WIN32_HANDLE> preprocessor symbols for more info.
-
-The configuration for a "naked" win32 using the Microsoft runtime
-libraries and raw winsocket select is:
-
- #define EV_USE_SELECT 1
- #define EV_SELECT_IS_WINSOCKET 1 /* forces EV_SELECT_USE_FD_SET, too */
-
-Note that winsockets handling of fd sets is O(n), so you can easily get a
-complexity in the O(n²) range when using win32.
-
-=head3 Limited number of file descriptors
-
-Windows has numerous arbitrary (and low) limits on things.
-
-Early versions of winsocket's select only supported waiting for a maximum
-of C<64> handles (probably owning to the fact that all windows kernels
-can only wait for C<64> things at the same time internally; Microsoft
-recommends spawning a chain of threads and wait for 63 handles and the
-previous thread in each. Sounds great!).
-
-Newer versions support more handles, but you need to define C<FD_SETSIZE>
-to some high number (e.g. C<2048>) before compiling the winsocket select
-call (which might be in libev or elsewhere, for example, perl and many
-other interpreters do their own select emulation on windows).
-
-Another limit is the number of file descriptors in the Microsoft runtime
-libraries, which by default is C<64> (there must be a hidden I<64>
-fetish or something like this inside Microsoft). You can increase this
-by calling C<_setmaxstdio>, which can increase this limit to C<2048>
-(another arbitrary limit), but is broken in many versions of the Microsoft
-runtime libraries. This might get you to about C<512> or C<2048> sockets
-(depending on windows version and/or the phase of the moon). To get more,
-you need to wrap all I/O functions and provide your own fd management, but
-the cost of calling select (O(n²)) will likely make this unworkable.
-
-=head2 PORTABILITY REQUIREMENTS
-
-In addition to a working ISO-C implementation and of course the
-backend-specific APIs, libev relies on a few additional extensions:
-
-=over 4
-
-=item C<void (*)(ev_watcher_type *, int revents)> must have compatible
-calling conventions regardless of C<ev_watcher_type *>.
-
-Libev assumes not only that all watcher pointers have the same internal
-structure (guaranteed by POSIX but not by ISO C for example), but it also
-assumes that the same (machine) code can be used to call any watcher
-callback: The watcher callbacks have different type signatures, but libev
-calls them using an C<ev_watcher *> internally.
-
-=item pointer accesses must be thread-atomic
-
-Accessing a pointer value must be atomic, it must both be readable and
-writable in one piece - this is the case on all current architectures.
-
-=item C<sig_atomic_t volatile> must be thread-atomic as well
-
-The type C<sig_atomic_t volatile> (or whatever is defined as
-C<EV_ATOMIC_T>) must be atomic with respect to accesses from different
-threads. This is not part of the specification for C<sig_atomic_t>, but is
-believed to be sufficiently portable.
-
-=item C<sigprocmask> must work in a threaded environment
-
-Libev uses C<sigprocmask> to temporarily block signals. This is not
-allowed in a threaded program (C<pthread_sigmask> has to be used). Typical
-pthread implementations will either allow C<sigprocmask> in the "main
-thread" or will block signals process-wide, both behaviours would
-be compatible with libev. Interaction between C<sigprocmask> and
-C<pthread_sigmask> could complicate things, however.
-
-The most portable way to handle signals is to block signals in all threads
-except the initial one, and run the signal handling loop in the initial
-thread as well.
-
-=item C<long> must be large enough for common memory allocation sizes
-
-To improve portability and simplify its API, libev uses C<long> internally
-instead of C<size_t> when allocating its data structures. On non-POSIX
-systems (Microsoft...) this might be unexpectedly low, but is still at
-least 31 bits everywhere, which is enough for hundreds of millions of
-watchers.
-
-=item C<double> must hold a time value in seconds with enough accuracy
-
-The type C<double> is used to represent timestamps. It is required to
-have at least 51 bits of mantissa (and 9 bits of exponent), which is
-good enough for at least into the year 4000 with millisecond accuracy
-(the design goal for libev). This requirement is overfulfilled by
-implementations using IEEE 754, which is basically all existing ones.
-
-With IEEE 754 doubles, you get microsecond accuracy until at least the
-year 2255 (and millisecond accuracy till the year 287396 - by then, libev
-is either obsolete or somebody patched it to use C<long double> or
-something like that, just kidding).
-
-=back
-
-If you know of other additional requirements drop me a note.
-
-
-=head1 ALGORITHMIC COMPLEXITIES
-
-In this section the complexities of (many of) the algorithms used inside
-libev will be documented. For complexity discussions about backends see
-the documentation for C<ev_default_init>.
-
-All of the following are about amortised time: If an array needs to be
-extended, libev needs to realloc and move the whole array, but this
-happens asymptotically rarer with higher number of elements, so O(1) might
-mean that libev does a lengthy realloc operation in rare cases, but on
-average it is much faster and asymptotically approaches constant time.
-
-=over 4
-
-=item Starting and stopping timer/periodic watchers: O(log skipped_other_timers)
-
-This means that, when you have a watcher that triggers in one hour and
-there are 100 watchers that would trigger before that, then inserting will
-have to skip roughly seven (C<ld 100>) of these watchers.
-
-=item Changing timer/periodic watchers (by autorepeat or calling again): O(log skipped_other_timers)
-
-That means that changing a timer costs less than removing/adding them,
-as only the relative motion in the event queue has to be paid for.
-
-=item Starting io/check/prepare/idle/signal/child/fork/async watchers: O(1)
-
-These just add the watcher into an array or at the head of a list.
-
-=item Stopping check/prepare/idle/fork/async watchers: O(1)
-
-=item Stopping an io/signal/child watcher: O(number_of_watchers_for_this_(fd/signal/pid % EV_PID_HASHSIZE))
-
-These watchers are stored in lists, so they need to be walked to find the
-correct watcher to remove. The lists are usually short (you don't usually
-have many watchers waiting for the same fd or signal: one is typical, two
-is rare).
-
-=item Finding the next timer in each loop iteration: O(1)
-
-By virtue of using a binary or 4-heap, the next timer is always found at a
-fixed position in the storage array.
-
-=item Each change on a file descriptor per loop iteration: O(number_of_watchers_for_this_fd)
-
-A change means an I/O watcher gets started or stopped, which requires
-libev to recalculate its status (and possibly tell the kernel, depending
-on backend and whether C<ev_io_set> was used).
-
-=item Activating one watcher (putting it into the pending state): O(1)
-
-=item Priority handling: O(number_of_priorities)
-
-Priorities are implemented by allocating some space for each
-priority. When doing priority-based operations, libev usually has to
-linearly search all the priorities, but starting/stopping and activating
-watchers becomes O(1) with respect to priority handling.
-
-=item Sending an ev_async: O(1)
-
-=item Processing ev_async_send: O(number_of_async_watchers)
-
-=item Processing signals: O(max_signal_number)
-
-Sending involves a system call I<iff> there were no other C<ev_async_send>
-calls in the current loop iteration and the loop is currently
-blocked. Checking for async and signal events involves iterating over all
-running async watchers or all signal numbers.
-
-=back
-
-
-=head1 PORTING FROM LIBEV 3.X TO 4.X
-
-The major version 4 introduced some incompatible changes to the API.
-
-At the moment, the C<ev.h> header file provides compatibility definitions
-for all changes, so most programs should still compile. The compatibility
-layer might be removed in later versions of libev, so better update to the
-new API early than late.
-
-=over 4
-
-=item C<EV_COMPAT3> backwards compatibility mechanism
-
-The backward compatibility mechanism can be controlled by
-C<EV_COMPAT3>. See L</PREPROCESSOR SYMBOLS/MACROS> in the L</EMBEDDING>
-section.
-
-=item C<ev_default_destroy> and C<ev_default_fork> have been removed
-
-These calls can be replaced easily by their C<ev_loop_xxx> counterparts:
-
- ev_loop_destroy (EV_DEFAULT_UC);
- ev_loop_fork (EV_DEFAULT);
-
-=item function/symbol renames
-
-A number of functions and symbols have been renamed:
-
- ev_loop => ev_run
- EVLOOP_NONBLOCK => EVRUN_NOWAIT
- EVLOOP_ONESHOT => EVRUN_ONCE
-
- ev_unloop => ev_break
- EVUNLOOP_CANCEL => EVBREAK_CANCEL
- EVUNLOOP_ONE => EVBREAK_ONE
- EVUNLOOP_ALL => EVBREAK_ALL
-
- EV_TIMEOUT => EV_TIMER
-
- ev_loop_count => ev_iteration
- ev_loop_depth => ev_depth
- ev_loop_verify => ev_verify
-
-Most functions working on C<struct ev_loop> objects don't have an
-C<ev_loop_> prefix, so it was removed; C<ev_loop>, C<ev_unloop> and
-associated constants have been renamed to not collide with the C<struct
-ev_loop> anymore and C<EV_TIMER> now follows the same naming scheme
-as all other watcher types. Note that C<ev_loop_fork> is still called
-C<ev_loop_fork> because it would otherwise clash with the C<ev_fork>
-typedef.
-
-=item C<EV_MINIMAL> mechanism replaced by C<EV_FEATURES>
-
-The preprocessor symbol C<EV_MINIMAL> has been replaced by a different
-mechanism, C<EV_FEATURES>. Programs using C<EV_MINIMAL> usually compile
-and work, but the library code will of course be larger.

-
-=item event
-
-A change of state of some external event, such as data now being available

-/*
- * general notes about epoll:
- *
- * a) epoll silently removes fds from the fd set. as nothing tells us
- * that an fd has been removed otherwise, we have to continually
- * "rearm" fds that we suspect *might* have changed (same
- * problem with kqueue, but much less costly there).
- * b) the fact that ADD != MOD creates a lot of extra syscalls due to a)
- * and seems not to have any advantage.
- * c) the inability to handle fork or file descriptors (think dup)
- * limits the applicability over poll, so this is not a generic
- * poll replacement.
- * d) epoll doesn't work the same as select with many file descriptors
- * (such as files). while not critical, no other advanced interface
- * seems to share this (rather non-unixy) limitation.
- * e) epoll claims to be embeddable, but in practise you never get
- * a ready event for the epoll fd (broken: <=2.6.26, working: >=2.6.32).
- * f) epoll_ctl returning EPERM means the fd is always ready.
- *
- * lots of "weird code" and complication handling in this file is due
- * to these design problems with epoll, as we try very hard to avoid
- * epoll_ctl syscalls for common usage patterns and handle the breakage
- * ensuing from receiving events for closed and otherwise long gone
- * file descriptors.
