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 timeout_duration due to scheduling or resource contention delays.

Contents

[edit] Parameters

sleep_duration - time duration to sleep

[edit] Return value

(none)

[edit] 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)

[edit] Example

#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
