    controlling the processor resources

    Does anyone know how I can keep my program from using 99% of my cpu percentage every time I run it? Is there a way to set some kind of limit, like say 10%?

    I have looked at <sys/resource.h> extensively, and all I have found is that it only allows the setting of memory limits.

    Please tell me if I have missed something or please point me in the direction of a header that does this.

    Thanks so much!

    Which OS and compiler?
    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.

    If you are on windows, there are windows API calls like SetThreadPriority. I haven't used them in years, but check msdn.

    I am currently using FreeBSD unix... but I would like to control it on any *nix. Also I am using GCC 3.45.

    Thanks

    The easiest way would be to call usleep every so often.

    try looking into the pthread library, there may be something in there for setting process/thread priorities

    ah yes, nice, forgot about that one. I had to use that once a couple years ago.
