Windows C++ nanosecond timing?

Question

Is there a way in C++ on windows to measure time in nanoseconds?

All i can find are linux solutions.

Answer 1

If you can run your own assembly, you could read the CPU's cycle counter and divide a cycle difference it by the CPU's clock rate:

static inline uint64_t get_cycles()
{
  uint64_t t;
  __asm__ __volatile__ ("rdtsc" : "=A"(t));
  return t;
}
