| 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.
This function may block for longer than sleep_duration due to scheduling or resource contention delays.
The standard recommends that a steady clock is used to measure the duration. If an implementation uses a system clock instead, the wait time may also be sensitive to clock adjustments.

[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 <chrono> #include <iostream> #include <thread> int main() { using namespace std::chrono_literals; std::cout << "Hello waiter\n" << std::flush; const auto start = std::chrono::high_resolution_clock::now(); std::this_thread::sleep_for(2000ms); const auto end = std::chrono::high_resolution_clock::now(); const std::chrono::duration<double, std::milli> elapsed = end - start; std::cout << "Waited " << elapsed << '\n'; }
Possible output:
Hello waiter Waited 2000.13 ms
