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
#include <iostream> #include <chrono> #include <thread> int main() { using namespace std::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
