    how do I determine the clocks per second on my machine?


    The subject pretty much says it all. As far as I understood that, the constant

    #define CLK_TCK 1000.0

    given in time.h probably isnīt really how it is like on my machine. A faster CPU would do more clocks per second than a slower one, wouldnīt it? And if so, how can I determine the real value?

    I believe that the clock length is constant regardless of CPU speed.
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    If you're trying to find the Mhz of your processor, then it's going to be specific to your operating system 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.
