My current Windows code uses a named event for inter-process communication. There can be many processes waiting on the event, when it's signaled, all the waiting processes are released and then the event returns to a non-signaled state. I use the PulseEvent function for this.
How do I do this in Linux? The pthread functions seem to be inter-thread communication. I don't see where semaphores can provide the same behavior as Windows has. The Posix semaphore seems to only release one waiting thread. If the semaphore could release all waiting threads then that would work. Is there something in Linux I'm missing?
It looks like a futex can provide the behavior of the Windows event.
