    Question Timing in C

    Hello all, I was wondering if anybody could help me with timing in C.
    Im trying to make a solar system program, and putting aside all the OpenGL worries I have, Ive come stuck on trying to get a function to execute periodically without fail, ie. every second, minute or how ever many times per second/usec it will execute. Ive see functions such as sleep() and usleep(), but they delay things from happening... If anybody could help me id be very thankfull.
    Konrad.

    Two seconds and a search engine provide lots of ways to do it.

    ANSI Standard? Use something like time in a loop.

    Non-ANSI, there are plenty of ways. (IE: OS dependant. Using select, etc.)

    Isn't this in the FAQ? Why yes, yes it is!

    Hope is the first step on the road to disappointment.

    Man the FAQ has become quite a resource since I last visited the site regularly. Too bad most questions asked are in the FAQ. Maybe the problem with newbies is their reading comprehension.

    I can not see how that helps me. Ive seen what is in the FAQ before, it will give you the time between two stages by subtracting two different times.

    I dont want that, i want to be able to be able to make a function run exactly every second, or minute or so many times per second...

    I dont think waiting for the difference between two times gets to a certain value will be accurate and specfic enough...

    Look into threads, running two or more portions of a program at the same time.

    This gets complicated, but it will do what you want.
