good stuff, just what I was looking for. Actually, I made something similar for Windows and was now looking for the same thing in linux. Here’s a suggestion for you: Why not make the start/stop functions inline? Actually, I used macros instead, which pretty much comes out to the same. The reason is: if you want to make multiple measurements, especially nested ones, you want to avoid any function overhead. Also, I added the capability to compute the average elapsed time for multiple measurements on the same loop.

The attached cpp file had the correct function but there was a typo in the post. Good catch, thanks.

Correct function:
timersub(&start,&stop,&result);

Thanks for the mods. However, both your links to the files point to the same file.
