That'd be different in different OS'es. But in many (most/all?) modern Linuxes, it would boil down to reading and parsing /proc/cpuinfo.

Edit: disclaimer, Linux'y guy googling somewhat randomly, but this link, http://www.bradwich.com/blog/2008/1/9/retrieving-current-cpu-clock-speed-under-windows/ might give some clues on how to do it with Windows.

This is not a C feature that you are looking for, but an operating system feature. Therefore it depends largely on that. Even among unixes there is no common way to this.
