As I've been told, RDTSC is a feature of pentium (and up) processers that tracks the number of processer cycles completed since the system last powered up, making it useful for calculating system uptime - but more importantly, it can be used to test code optimization and so on. My question : How do I get this value and use in in a DJGPP program? If anyone has a function already written, that'd be great.
