C++ (Cpp) to_ns Examples

Example #1

File: 014.c Project: japaric/eulermark.rs

int main(int argc, char *argv[]) {
  if (argc == 1) {
    printf("%lu\n", f());
  } else if (argc == 2) {

    uint64_t i = 0;
    uint64_t iters = atol(argv[1]);

    clock_gettime(CLOCK_MONOTONIC, &start);
    for (; i < iters; i++) {
      f();
      asm("");
    }
    clock_gettime(CLOCK_MONOTONIC, &end);

    printf("%lu", to_ns(end) - to_ns(start));
  } else {
