I would like to make clear this point for Windows98 and gpp-2.95.3

I have some function foo().
I would like to measure its average cost-time in nanoseconds, something like
:

start = ????
          for (i = 0; i < iters; i++)
               foo ();
end = ????
printf("Avg time = %lld nsec\n", (end - start) / iters);

Is it possible ?
