Sleep for milliseconds

Solution 1:

In C++11, you can do this with standard library facilities:

#include <chrono>
#include <thread>

std::this_thread::sleep_for(std::chrono::milliseconds(x));

Clear and readable, no more need to guess at what units the sleep() function takes.

Solution 2:

Note that there is no standard C API for milliseconds, so (on Unix) you will have to settle for usleep, which accepts microseconds:

#include <unistd.h>

unsigned int microseconds;
...
usleep(microseconds);

Solution 3:

To stay portable you could use Boost::Thread for sleeping:

#include <boost/thread/thread.hpp>

int main()
{
    //waits 2 seconds
    boost::this_thread::sleep( boost::posix_time::seconds(1) );
    boost::this_thread::sleep( boost::posix_time::milliseconds(1000) );

    return 0;
}

This answer is a duplicate and has been posted in this question before. Perhaps you could find some usable answers there too.

Solution 4:

In Unix you can use usleep.

In Windows there is Sleep.

Solution 5:

Depending on your platform you may have usleep or nanosleep available. usleep is deprecated and has been deleted from the most recent POSIX standard; nanosleep is preferred.
