Condition Variables
The general usage pattern is that one thread locks a mutex and then calls
wait on an instance of condition_variable or condition_variable_any. When the thread is woken from the wait, then it checks to see if the appropriate condition is now true, and continues if so. If the condition is not true, then the thread then calls wait again to resume waiting.(涓枃鍙傝?/a>)lock is passed to wait()錛?wait() will atomically add the thread to the set of threads waiting on the condition variable, and unlock the mutex. When the thread is woken, the mutex will be locked again before the call to wait returns. This allows other threads to acquire the mutex in order to update the shared data, and ensures that the data associated with the condition is correctly synchronized. In the mean time, another thread sets the condition to true, and then calls either notify_one() or notify_all() on the condition variable to wake one waiting thread or all the waiting threads respectively.
