Win32::Mutex - Use Win32 mutex objects from Perl
SYNOPSIS
require Win32::Mutex;
$mutex = Win32::Mutex->new($initial,$name);
$mutex->wait;
DESCRIPTION
This module allows access to the Win32 mutex objects. The "wait"
method and "wait_all" & "wait_any" functions are inherited from the
"Win32::IPC" module.
Methods
$mutex = Win32::Mutex->new([$initial, [$name]])
Constructor for a new mutex object. If $initial is true, requests
immediate ownership of the mutex (default false). If $name is
omitted, creates an unnamed mutex object.
If $name signifies an existing mutex object, then $initial is
ignored and the object is opened. If this happens, $^E will be set
to 183 (ERROR_ALREADY_EXISTS).
$mutex = Win32::Mutex->open($name)
Constructor for opening an existing mutex object.
$mutex->release
Release ownership of a $mutex. You should have obtained ownership
of the mutex through "new" or one of the wait functions. Returns
true if successful.
$mutex->wait([$timeout])
Wait for ownership of $mutex. See "Win32::IPC".
Deprecated Functions and Methods
Win32::Mutex still supports the ActiveWare syntax, but its use is
deprecated.
Create($MutObj,$Initial,$Name)
Use "$MutObj = Win32::Mutex->new($Initial,$Name)" instead.
Open($MutObj,$Name)
Use "$MutObj = Win32::Mutex->open($Name)" instead.
