mutex互斥锁必须是普通锁(PTHREAD_MUTEX_TIMED_NP)或者适应锁(PTHREAD_MUTEX_ADAPTIVE_NP),且在调用pthread_cond_wait()前必须由本线程加锁(pthread_mutex_lock()),而在更新条件等待队列以前,mutex保持锁定状态,并在线程挂起进入等待前解锁。在条件满足从而离开pthread_cond_wait()之前,mutex将被重新加锁,以与进入...
Linux初始化和销毁互斥锁的接口是pthread_mutex_init()和pthead_mutex_destroy(),对于加锁和解锁则有pthread_mutex_lock()、pthread_mutex_trylock()和pthread_mutex_unlock()。这些接口的完整定义如下: 1:pthread_mutex_init(pthread_mutex_t*mutex,constpthread_mutexattr_t*attr);// 初始化锁变量mutex。// at...
