This overload might be employed to disregard spurious awakenings though waiting for a particular issue to be legitimate.

The highest-level purpose might converse its return value or an exception to your caller through std::assure or by modifying shared variables (which may involve synchronization, see std::mutex and std::atomic).

Whether or not the shared variable is atomic, it need to be modified while owning the mutex to properly publish the modification to your waiting thread.

The best-level perform may possibly connect its return value or an exception to your caller by using std::promise or by modifying shared variables (which may call for synchronization, see std::mutex and std::atomic).

The conventional endorses which the clock tied to abs_time be used to measure time; that clock is not necessary to become a monotonic clock. There aren't any ensures regarding the conduct of this operate In case the clock is modified discontinuously, but the present implementations change abs_time from Clock to std::chrono::system_clock and delegate to POSIX pthread_cond_timedwait so the wait around honors adjustments on the technique clock, although not on the consumer-presented Clock.

Even if notified under lock, overload (1) will make no assures with regard to the point out with the Stages of sleep affiliated predicate when returning resulting from timeout.

If the future is the results of a contact to std::async that applied lazy evaluation, this purpose returns instantly without the need of waiting around.

This enables the purpose to examine if stop is asked for through its execution, and return if it's got.

In case the purpose file returns a price or throws an exception, it can be saved from the shared point out obtainable from the std::long run that std::async returns to your caller. [edit] Deferred invocation
