    Just curious if the iPhone uses mutual exclusion in it's Operating System?

    If can someone explain how it does?

    Sorry for my lack of knowledge to put the pieces together, but does that mean it doesn't use mutual exclusion then, or it doesn't lol?

    I assumed if you were asking a technical question like that then that would be a sufficient answer. It means mutexes are available within the treading model. Most likely they are used, but their availability does not imply or guarantee their usage.

    Haha yeah, I'm in a OS class and still learning a lot about these components.
    Do you know of a resource that explains this in a bit more death about how they are handled, as Google is failing me extremely. :D

    With reference to the iPhone? No. Otherwise Googling POSIX Mutex gives me sensible answers.
