-
- Win32::Mutex - Use Win32 mutex objects from Perl
-
- =head1 SYNOPSIS
-
- require Win32::Mutex;
-
- $mutex = Win32::Mutex->new($initial,$name);
- $mutex->wait;
-
- =head1 DESCRIPTION
-
- This module allows access to the Win32 mutex 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 $mutex = Win32::Mutex->new([$initial, [$name]])
-
- Constructor for a new mutex object. If C<$initial> is true, requests
- immediate ownership of the mutex (default false). If C<$name> is
- omitted, creates an unnamed mutex object.
-
- If C<$name> signifies an existing mutex object, then C<$initial> is
- ignored and the object is opened.
-
- =item $mutex = Win32::Mutex->open($name)
-
- Constructor for opening an existing mutex object.
-
- =item $mutex->release
-
- Release ownership of a C<$mutex>. You should have obtained ownership
- of the mutex through C<new> or one of the wait functions. Returns
- true if successful.
-
- =item $mutex->wait([$timeout])
-
- Wait for ownership of C<$mutex>. See L<"Win32::IPC">.

- deprecated.
