Try "bench.h"; it lets you put a START_TIMER; and STOP_TIMER("name"); into your code, allowing you to arbitrarily benchmark any section of code (note: only recommended for short sections, not things taking dozens of milliseconds or more). Its accurate to the clock cycle, though in some rare cases it can change how the code in between is compiled, in which case you're better off with a profiler (though profilers are generally more effort to use for specific sections of code).

It only works on x86.
