Using "pth_cond_notify", a thread just wants to notify another thread that, an event has occurred and it doesn't mean that it should also relinquish the CPU. Its upto that thread whether to continue with the processing or not. Is there any other call in Pth which can be used for sending a notification to a thread, without relinquishing the CPU ?
