C Code Timer or Clock

[MaDHaVoK]

I am trying to create a timer.. that would start at 00:00:00:0 (HH:MM:SS:Tenth S) and go to 11:59:59.9 then reset to zero. My problem is I would like this to be accurate to the tenth of second... Any links where I could get help on this?

Thanks!

You could use a normal int or long and just increment it every 10th of a second (use nanosleep or usleep to keep time), but unless you're using a real-time scheduler you're not guaranteed it'll be perfect, you should use gettimeofday calls to verify how long you slept.

It is very likely that any solution to your problem is going to be very Operating-System specific.
