 """ Tries to acquire one or the given number of permits, if they are available, and returns immediately, with the value ``true``, reducing the number of available permits by the given amount. If there are insufficient permits and a timeout is provided, the current thread becomes disabled for thread scheduling purposes and lies dormant until one of following happens: * some other thread invokes the release() method for this semaphore and the current thread is next to be assigned a permit, or * some other thread interrupts the current thread, or * the specified waiting time elapses. If there are insufficient permits and no timeout is provided, this method will return immediately with the value ``false`` and the number of available permits is unchanged. :param permits: (int), the number of permits to acquire (optional). :param timeout: (long), the maximum time in seconds to wait for the permit(s) (optional). :return: (bool), ``true`` if desired amount of permits was acquired, ``false`` otherwise.
