How to measure time in milliseconds using ANSI C?
...ate on many systems.
You can use this function like this:
struct timeval tval_before, tval_after, tval_result;
gettimeofday(&tval_before, NULL);
// Some code you want to time, for example:
sleep(1);
gettimeofday(&tval_after, NULL);
timersub(&tval_after, &tval_before, &tval_...

How to get the current time in milliseconds from C in Linux?
...mespec spec;
clock_gettime(CLOCK_REALTIME, &spec);
s = spec.tv_sec;
ms = round(spec.tv_nsec / 1.0e6); // Convert nanoseconds to milliseconds
if (ms > 999) {
s++;
ms = 0;
}

...ts. You'll get a structure like the following:
struct timeval {
time_t tv_sec;
suseconds_t tv_usec;
}
EDIT: As the two comments below suggest, clock_gettime(CLOCK_MONOTONIC) is a much better choice if you have it available, which should be almost everywhere these days.

You functionally want this:

Is there an alternative sleep function in C to milliseconds?
