    The SyncSemaphore class

    (PECL sync >= 1.0.0)

    Introduzione

    A cross-platform, native implementation of named and unnamed semaphore objects.

    A semaphore restricts access to a limited resource to a limited number of instances. Semaphores differ from mutexes in that they can allow more than one instance to access a resource at one time while a mutex only allows one instance at a time.

    Sommario della classe

    class SyncSemaphore {
    /* Metodi */
    public __construct(string $name = ?, int $initialval = 1, bool $autounlock = true)
    public lock(int $wait = -1): bool
    public unlock(int &$prevcount = ?): bool
    }
