in reply to How to sleep 1 microsecond?

What are you trying to achieve with a 1us sleep? Even if you do find code that can achieve that some of the time, it will be highly unreliable for most common operating systems.

    Not to mention, the various sleep functions only guarantee that they sleep at least the amount of time specified. You can't really do accurate timing with them.

    Time::HiRes::ualarm might work better though...

      Thanks but the ualarm function is like usleep which is not reliable if I want to count a few microsecond.

    Concur that usleep/nanosleep are not reliable in this case :-(
