This overload can be utilised to disregard spurious awakenings even though awaiting a specific affliction to become true.

remaining - pointer to the thing To place the remaining time on interruption. Could be NULL, wherein circumstance it truly is ignored

Although the shared variable is atomic, it should be modified although proudly owning the mutex to properly publish the modification towards the waiting around thread.

The very best-stage functionality may talk its return worth or an exception to your caller by using std::promise or by modifying shared variables (which may demand synchronization, see std::mutex and std::atomic).

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 isn't any guarantees concerning the habits of the purpose If your clock is altered discontinuously, but the prevailing implementations transform abs_time from Clock to std::chrono::system_clock Stages of sleep and delegate to POSIX pthread_cond_timedwait so which the wait honors changes to your procedure clock, although not into the person-delivered Clock.

Regardless of whether notified underneath lock, overload (one) can make no ensures in regards to the condition on the linked predicate when returning on account of timeout.

If the long run is the results of a get in touch with to std::async that made use of lazy evaluation, this function returns quickly without waiting around.

This enables the functionality to check if quit has become asked for all through its execution, and return if it has.

In the event the std::long run attained from std::async is not moved from or bound to a reference, the destructor on the std::long run will block at the conclusion of the full expression until finally the asynchronous operation completes, fundamentally earning code such as the following synchronous:
