Hi Everyone.

I have been fooling around with some graphics programming and I am at the point now where I need to start thinking about timing. Can anyone give me a suggestion for a high resolution timer in linux? I have been fooling around with "gettimeofday" and that seems to work. I just want to make sure that there isn't a better, more well known way.

Also what happens when gettimeofday overflows? (I think it occurs about ever 49 days) But timing could get seriously screwed up unless there is a way to trap for that.

Thanks,

Sam

getitimer(), setitimer(), gettimeofday()

all use the struct timeval. That's about it for usec timing.

When unix was young most systems had trouble staying up for four weeks let alone 49 days. I think the value rolls over to zero.

if you want something faster/more accurate look at this.
