* Extra characters can be detected by comparing the tok->char_offset against

* The tokener does \b not maintain an internal buffer so the caller is

* parameter starting with the extra characters.

* This interface is presently not 64-bit clean due to the int len argument
* so the function limits the maximum string size to INT32_MAX (2GB).
* If the function is called with len == -1 then strlen is called to check
* the string length is less than INT32_MAX (2GB)
*
* Example:
* @code
json_object *jobj = NULL;
const char *mystring = NULL;
int stringlen = 0;

mystring = ... // get JSON string, e.g. read from file, etc...

// Handle errors, as appropriate for your application.
}
if (tok->char_offset < stringlen) // XXX shouldn't access internal fields
{
// Handle extra characters after parsed object as desired.
// e.g. issue an error, parse another object from that point, etc...
}
// Success, use jobj here.
@endcode
