How to write a C program that executes a statement every N milliseconds?

[GMaximus]

The topic says it all. I would like to write a C program that runs on Linux that executes a statement every N milliseconds, and was wondering if anyone could assist me.

You could use the Sleep() function in Windows API, but it's not extremely precise.

Thanks, but I should have mentioned that this is needs to run on Linux 🙂 Updated original post.

In Linux, try this.

If you need help converting between microseconds/milliseconds, etc:

There is also nanosleep if you need nanosecond precision. But if you do, you probably shouldn't be using C because of the overhead involved.

C by Dissection:

void sleep(unsigned seconds);

Supends the curent process from execution for the number of seconds requested. Time is approximate.

Awesome man, this seems to be exactly what I'm looking for. Thanks a bunch!

No problem...make sure my micro-->millisecond calculations were right. I'm not the best at math...

Heh I'm the same way, but its right. Hard to screw up a simple multiply 🙂
