Win32::Event - Use Win32 event objects from Perl
This document describes version 1.09 of Win32::Event, released November 15, 2014 as part of Win32-IPC version 1.11.
use Win32::Event;
$event = Win32::Event->new($manual,$initial,$name);
$event->wait();
This module allows access to the Win32 event objects. The wait
method and wait_all & wait_any functions are inherited from the
the Win32::IPC manpage module.
$manual is true, you must
manually reset the event after it is signalled (the default is false).
If $initial is true, the initial state of the object is signalled
(default false). If $name is omitted or undef, creates an
unnamed event object.
If $name signifies an existing event object, then $manual and
$initial are ignored and the object is opened. If this happens,
$^E will be set to 183 (ERROR_ALREADY_EXISTS).
open($name)PulseEvent for
details.
Signal the $event and then immediately reset it. If $event is a
manual-reset event, releases all threads currently blocking on it. If
it's an auto-reset event, releases just one thread.
If no threads are waiting, just resets the event.
It returns a true value if successful, or zero on failure
(additional error information can be found in $^E).
$event to nonsignalled. It returns a true value if
successful, or zero on failure (additional error information can be
found in $^E).
$event to signalled. It returns a true value if
successful, or zero on failure (additional error information can be
found in $^E).
wait([$timeout])$event to be signalled. See the Win32::IPC manpage.
None.
Win32::Event requires no configuration files or environment variables.
It runs under 32-bit or 64-bit Microsoft Windows, either natively or under Cygwin.
Prior to version 1.06, the Win32 IPC modules treated undef values
differently. In version 1.06 and later, passing undef as the value
of an optional parameter is the same as omitting that parameter. In
previous versions, undef was interpreted as either the empty string
or 0 (along with a warning about ``Use of uninitialized value...'').
Signal handlers will not be called during the wait method.
See BUGS AND LIMITATIONS in the Win32::IPC manpage for details.
