time functions help?

Hello to anyone who can help me!

I am in need of some help in procuring a more exact timing scheme in C for use with gcc.

I manage to get a timing in seconds just fine using difftime(). However, I need more accurate.. milliseconds... no clue.

Please help?

If you are planning to get the time in milliseconds after the last second, use gettimeofday(struct timeval *tp, void *tzp), after who's call, the tp.tv_usec should return you the microseconds.

You can also use gethrtime() in section 3C if you want nanoseconds.
