=head1 NAME
Win32::Event - Use Win32 event objects from Perl
=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<$name> is omitted, creates an unnamed event
object.
If C<$name> signifies an existing event object, then C<$manual> and
C<$initial> are ignored and the object is opened.
=item $event = Win32::Event->open($name)
Constructor for opening an existing event object.
=item $event->pulse
Signal the C<$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.
=item $event->reset
Reset the C<$event> to nonsignalled.
=item $event->set
Set the C<$event> to signalled.
=item $event->wait([$timeout])
Wait for C<$event> to be signalled. See L<"Win32::IPC">.
