Sleep operation in C++ on OS X

Question

I want to perform the above mentioned operation in milliseconds as the unit. Which library and function call should I prefer?

Answer 1

EDIT 2017: C++11 sleep_for is the right way to do this. Please see Xornad's answer, below.

C++03:

Since Mac OS X is Unix-based, you can almost always just use the standard linux functions!

In this case you can use usleep (which takes a time in microseconds) and just multiply your milliseconds by 1000 to get microseconds.

#include <unistd.h>
int main () {
    usleep(1000); // will sleep for 1 ms
    usleep(1); // will sleep for 0.001 ms
    usleep(1000000); // will sleep for 1 s
}

For more info on this function, check out the Linux man page:
