This overload can be utilised to ignore spurious awakenings while looking ahead to a certain issue to become legitimate.

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

three) Registers *this for your length of the contact, to get notified if a prevent request is manufactured on stoken's linked stop-condition; it can be then equivalent to

The decision to std::async synchronizes with the decision to file, and the completion of f is sequenced before making the shared condition All set.

The standard recommends that the clock tied to abs_time be used to measure time; that clock isn't required to be considered a monotonic clock. There aren't any ensures regarding the conduct of this perform In the event 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 for the program clock, but not for the user-supplied Clock.

The conventional suggests that a gradual clock is accustomed to measure the length. If an implementation makes use of a program clock as an alternative, the wait time might also be sensitive to clock changes.

The perform also may block until eventually soon after sleep_time is reached as Stages of sleep a consequence of course of action scheduling or source contention delays.

The category thread represents one thread of execution. Threads permit many functions to execute concurrently.

When the operate file returns a price or throws an exception, it truly is saved while in the shared condition available from the std::long run that std::async returns to your caller. [edit] Deferred invocation
