    Aloha to all who read this.

    IM SICK OF SEMAPHORES.

    I have an exam tomorrow morning at 9. A definate question is going to be on Semaphores. I know roughly what the do, but theres no way Ill be able to do a full question on then with an example.

    No matter how many times I try to get to grips with these bloody semaphores, I just can't get it. Everything else in operating systems is fine. No problems whatsoever, just this bloody thing.

    Can anyone explain a semaphore for me in plain english. A way that easy to understand and remember?

    Much appreciated all!

    Thanks, got it this mornin' b4 the exam.

    My lecturer went and asked a horrible question on Semaphores and asked to show an example of a number of interacting semaphores using psuedo code.

    The conceeeept was vague enough to me, but that was just rediculous!:confused:
