Defined in header <thread>
template< class Rep, class Period > void sleep_for( const std::chrono::duration<Rep, Period>& sleep_duration );		(since C++11)

Blocks the execution of the current thread for at least the specified sleep_duration.

A steady clock is used to measure the duration. This function may block for longer than sleep_duration due to scheduling or resource contention delays.

Parameters

sleep_duration

-

time duration to sleep

Return value

(none)

Exceptions

Any exception thrown by clock, time_point, or duration during the execution (clocks, time points, and durations provided by the standard library never throw)

Example

Run this code

#include <iostream>
#include <chrono>
#include <thread>
 
int main()
{
    std::cout << "Hello waiter" << std::endl;
    std::chrono::milliseconds dura( 2000 );
    std::this_thread::sleep_for( dura );
    std::cout << "Waited 2000 ms\n";
}

Output:

Hello waiter
Waited 2000 ms
