While still holding the mutex lock, our thread will call pthread_cond_wait(&mycond,&mymutex).

锁定互斥对象时，线程将调用 pthread_cond_wait(&mycond,&mymutex)。

Doing so awakens all the reader threads that were waiting on the condition variable _cond; the reader threads now implicitly compete for the mutex lock as and when it is released.

这么做会唤醒所有等待条件变量_ cond的读线程；读线程现在隐式地争夺互斥锁。
