    semaphores. I'm looking some hints to get started,
    I'm kind of new to server/client stuff. Refences to cool
    programexamples, programmingtips or ideas on how to
    get started are greatfully accepted

    Kind Regards Ylva Wandel

    semaphores? weird, I've never heard of communicating with a semaphore. Myabe it's a different type of semaphore, but they aren't kernel objects are they?

    I don't know but this is what I read:

    To implement semaphores correctly the test of a semaphores value and the decrementing of this value must be an atomic operation. For tghis reason semaphores are normally impleneted inside the kernel.

    It's what sailors use when they wave flags at each other over a distance
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
