std::this_thread::sleep_until - cppreference.com (original) (raw)
| | | | | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | | ------------- | | template< class Clock, class Duration > void sleep_until( const std::chrono::time_point<Clock, Duration>& sleep_time ); | | (since C++11) |
Blocks the execution of the current thread until specified sleep_time has been reached.
Clock must meet the Clock requirements. The program is ill-formed if std::chrono::is_clock_v<Clock> is false.(since C++20)
The standard recommends that the clock tied to sleep_time be used, in which case adjustments of the clock may be taken into account. Thus, the duration of the block might be more or less than sleep_time - Clock::now() at the time of the call, depending on the direction of the adjustment and whether it is honored by the implementation. The function also may block until after sleep_time has been reached due to process scheduling or resource contention delays.
