=head1 NAME

Win32::Event - Use Win32 event objects from Perl

=head1 VERSION

This document describes version 1.09 of
Win32::Event, released November 15, 2014
as part of Win32-IPC version 1.11.

=head1 SYNOPSIS

	use Win32::Event;

	$event = Win32::Event->new($manual,$initial,$name);
	$event->wait();

=head1 DESCRIPTION

This module allows access to the Win32 event objects.  The C<wait>
method and C<wait_all> & C<wait_any> functions are inherited from the
L<Win32::IPC> module.

=head2 Methods

=over 4

=item $event = Win32::Event->new([$manual, [$initial, [$name]]])

Constructor for a new event object.  If C<$manual> is true, you must
manually reset the event after it is signalled (the default is false).
If C<$initial> is true, the initial state of the object is signalled
(default false).  If C<$name> is omitted or C<undef>, creates an
unnamed event object.

If C<$name> signifies an existing event object, then C<$manual> and
C<$initial> are ignored and the object is opened.  If this happens,
C<$^E> will be set to 183 (ERROR_ALREADY_EXISTS).

=item $event = Win32::Event->open($name)

Constructor for opening an existing event object.

=item $event->pulse

B<Microsoft has stated this function is unreliable and should be
avoided.> Consult Microsoft's documentation for C<PulseEvent> for
details.

Signal the C<$event> and then immediately reset it.  If C<$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 C<$^E>).

=item $event->reset

Reset the C<$event> to nonsignalled.  It returns a true value if
successful, or zero on failure (additional error information can be
found in C<$^E>).

=item $event->set

Set the C<$event> to signalled.  It returns a true value if
successful, or zero on failure (additional error information can be
found in C<$^E>).

=item $event->wait([$timeout])

Wait for C<$event> to be signalled.  See L<Win32::IPC>.

=back

=head1 DIAGNOSTICS

None.

=head1 CONFIGURATION AND ENVIRONMENT

Win32::Event requires no configuration files or environment variables.

It runs under 32-bit or 64-bit Microsoft Windows, either natively or
under Cygwin.

=head1 DEPENDENCIES

L<Win32::IPC>

=head1 INCOMPATIBILITIES

Prior to version 1.06, the Win32 IPC modules treated C<undef> values
differently.  In version 1.06 and later, passing C<undef> as the value
of an optional parameter is the same as omitting that parameter.  In
previous versions, C<undef> was interpreted as either the empty string
or 0 (along with a warning about "Use of uninitialized value...").

=head1 BUGS AND LIMITATIONS

Signal handlers will not be called during the C<wait> method.
See L<Win32::IPC/"BUGS AND LIMITATIONS"> for details.
