Win32::Event - Use Win32 event objects from Perl
This document describes version 1.09 of Win32::Event, released January 14, 2012 as part of Win32-IPC version 1.09.
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_any functions are inherited from the Win32::IPC module.
- $event = Win32::Event->new([$manual, [$initial, [$name]]])
Constructor for a new event object. If
$manualis true, you must manually reset the event after it is signalled (the default is false). If
$initialis true, the initial state of the object is signalled (default false). If
$nameis omitted or
undef, creates an unnamed event object.
$namesignifies an existing event object, then
$initialare ignored and the object is opened. If this happens,
$^Ewill be set to 183 (ERROR_ALREADY_EXISTS).
- $event = Win32::Event->open($name)
Constructor for opening an existing event object.
Microsoft has stated this function is unreliable and should be avoided. Consult Microsoft's documentation for
$eventand then immediately reset it. If
$eventis 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
$eventto nonsignalled. It returns a true value if successful, or zero on failure (additional error information can be found in
$eventto signalled. It returns a true value if successful, or zero on failure (additional error information can be found in
$eventto be signalled. See Win32::IPC.
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 Win32::IPC for details.
