If you're using POSIX threads (pthreads), then pthread_cond_wait and (in your case) pthread_cond_broadcast are your friends. :-)

If you are using Win32, then you can use a manual-reset Event . Your parent thread would call SetEvent() and could wake up all child threads waiting for that object with a function such as WaitForSingleObject() .
