会发生什么事时，收购了它的线程退出到互斥体？ [英] What happens to Mutex when the thread which acquired it exits?

问题描述

假设有两个线程，主线程和线程说B（由主创建）。若B获得一个互斥体（说pthread_mutex），它已呼吁了pthread_exit在开锁。那么会发生什么情况互斥？它是否成为自由？

Suppose there are two threads, the main thread and say thread B(created by main). If B acquired a mutex(say pthread_mutex) and it has called pthread_exit without unlocking the lock. So what happens to the mutex? Does it become free?

推荐答案

没了。互斥remaines锁定。究竟发生了这样的锁取决于其类型，你可以阅读有关 或这里

nope. The mutex remaines locked. What actually happens to such a lock depends on its type, You can read about that here or here
