Win32::Semaphore

The Win32::Semaphore module implements semaphores, synchronizing access to shared resources. The constructor new creates a new semaphore object and sets the initial count and the maximum count of the semaphore. The constructor has the following syntax:

$sem = Win32::Semaphore->new(init, max, [name]);

• init
• The initial count of the semaphore.
• max
• The maximum count of the semaphore.
• name
• A string containing a name of the semaphore.

The open constructor opens an existing semaphore object specified by name:

$sem = Win32::Semaphore->open(name);

• wait
• release
