This overload could be utilised to disregard spurious awakenings when awaiting a particular situation to become correct.

The highest-level purpose might converse its return price or an exception towards the caller by means of std::guarantee or by modifying shared variables (which can need synchronization, see std::mutex and std::atomic).

three) Registers *this for your period of this call, for being notified if a prevent ask for is made on stoken's related halt-state; it really is then reminiscent of

The decision to std::async synchronizes with the call to f, as well as the completion of file is sequenced before you make the shared point out ready.

The conventional endorses that the clock tied to abs_time be used to measure time; that clock will not be needed to certainly be a monotonic clock. There isn't any assures concerning the actions of the functionality Should the clock is altered discontinuously, but the prevailing implementations transform abs_time from Clock to std::chrono::system_clock and delegate to POSIX pthread_cond_timedwait so which the wait honors adjustments to the method clock, but not to the user-supplied Clock.

Even though notified below lock, overload (1) tends to make no guarantees concerning the state from the related predicate when returning because of timeout.

If the long run is the result of a phone to std::async that utilized lazy analysis, this perform returns promptly with out ready.

This permits the perform to check if Stages of sleep end has long been requested throughout its execution, and return if it's.

If your std::future obtained from std::async just isn't moved from or certain to a reference, the destructor with the std::future will block at the end of the total expression right up until the asynchronous Procedure completes, effectively making code like the next synchronous:
