原文如下：If the count field is not negative, the function sets sleepers to 0 and exits from the loop. It tries to wake up another process in the semaphore wait queue (but in our scenario, the queue is now empty) and terminates holding the semaphore. On exit, both the count field and the sleepers field are set to 0, as required when the semaphore is closed but no process is waiting for it.作者: xiaozhaoz 時間: 2006-04-13 10:44
