This overload could possibly be utilized to disregard spurious awakenings even though looking forward to a specific affliction to be genuine.
The very best-amount perform may perhaps talk its return benefit or an exception for the caller by using std::assure or by modifying shared variables (which may involve synchronization, see std::mutex and std::atomic).
Even when the shared variable is atomic, it have to be modified though owning the mutex to correctly publish the modification on the ready thread.
The very best-degree purpose may perhaps communicate its return worth or an exception on the caller by means of std::assure or by modifying shared variables (which may demand synchronization, see std::mutex and std::atomic).
The normal recommends that the clock tied to abs_time be accustomed to measure time; that clock just isn't necessary to be considered a monotonic clock. There are no guarantees concerning the actions of the purpose If your clock is altered discontinuously, but the present implementations convert abs_time from Clock to std::chrono::system_clock and delegate to POSIX pthread_cond_timedwait so the wait around honors adjustments towards the system clock, although not for the user-furnished Clock.
Even though notified under lock, overload (one) would make no guarantees concerning the state of the associated predicate when returning due to timeout.

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

This permits the perform to check if end has long been requested in the course of its execution, and return if it's.
Threads start off execution straight away upon construction in the linked thread item (pending any OS scheduling delays), starting off at the best-level perform offered being a constructor argument. The return worth of the best-amount functionality is ignored and if it terminates by Stages of sleep throwing an exception, std::terminate is known as.
