| 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.

[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
Run this code
#include <iostream> #include <chrono> #include <thread> int main() { using namespace std::chrono_literals; std::cout << "Hello waiter" << std::endl; auto start = std::chrono::high_resolution_clock::now(); std::this_thread::sleep_for(2s); auto end = std::chrono::high_resolution_clock::now(); std::chrono::duration<double, std::milli> elapsed = end-start; std::cout << "Waited " << elapsed.count() << " ms\n"; }
Possible output:
Hello waiter Waited 2000.12 ms
