ABSTRACT:
The method and apparatus of this invention provide a condition variable that has a time-out capability for an operating system that does not have one. A condition variable allows concurrent programming and provides high level communication between threads. The condition variable allows threads to wait within a mutex and allows broadcast signals to wake up waited threads. The condition variable is implemented by using counters to count the number of waited threads, the number of signals being sent to the waited threads, and semaphore, and means for mutually locking the thread to access the counters.
