WebPthread_cond_wait () is called by a thread when it wants to block and wait for a condition to be true. It is assumed that the thread has locked the mutex indicated by the second parameter. The thread releases the mutex, and blocks until awakened by a pthread_cond_signal () call from another thread. Webpthread_cond_timedwait()functions are used to block on a condition variable. They are called with mutexlocked by the calling thread or undefined behaviour will result.
