pthread_mutex_unlock是可以解除鎖定 mutex 所指向的互斥鎖的函式。...... pthread_mutex_lock,pthread_mutex_unlock這幾個函式以完成鎖的初始化,鎖的銷毀,上鎖和釋...
pthread_mutex_trylock是一個計算機函式,非阻塞的鎖定互斥鎖。...... pthread_mutex_unlock(&mut1);usleep(1000);}pthread_mutex_trylock()調用在參數mutex指定的...
pthread_mutex_unlock(): 釋放互斥鎖 pthread_cond_init():初始化條件變數 pthread_cond_destroy():銷毀條件變數 pthread_cond_signal(): 喚醒第一個調用pthread_...
pthread_cond_signal即可以放在pthread_mutex_lock和pthread_mutex_unlock之間,也可以放在pthread_mutex_lock和pthread_mutex_unlock之後,但是各有優缺點。...

pthread_cond_init,是一條用來初始化的條件變數。...... ("thead1:%d\n",i); pthread_mutex_unlock(&mutex);//*解鎖互斥量*/ printf("Up Mutex\n"); ...
鎖操作主要包括加鎖pthread_mutex_lock()、解鎖pthread_mutex_unlock()和測試加鎖 pthread_mutex_trylock()三個,不論哪種類型的鎖,都不可能被兩個不同的執行緒...
這個調用就是pthread_mutex_trylock。如果需要的話,該調用允許一個執行緒有效地忙等待。最後,pthread_mutex_unlock用來給一個互斥量解鎖,並在一個或多個執行緒等待它的...
