No synchronization is executed on *this by itself. Concurrently calling join() on the same thread item from a number of threads constitutes an information race that results in undefined actions.

std::launch::deferred or has supplemental bits established, it's going to fall again to deferred invocation or perhaps the implementation-defined insurance policies In such cases.
remaining - pointer to the object To place the remaining time on interruption. May be NULL, where case it can be dismissed
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 highest-amount function could converse its return benefit or an exception to the caller by way of std::guarantee or by modifying shared variables (which can have to have synchronization, see std::mutex and std::atomic).
Whether or not the clock in use is std::chrono::steady_clock or One more monotonic clock, a process clock adjustment may perhaps induce a spurious wakeup.
Although notified underneath lock, overload (one) helps make no guarantees about the point out on the connected predicate when returning as a result of timeout.
This overload might be used to disregard spurious awakenings even though looking forward to a specific ailment to be real.
This function may possibly block for longer than sleep_duration resulting from scheduling or resource rivalry delays.
period and remaining might place at exactly the same item, which simplifies re-functioning the operate following a signal.
A semaphore is a light-weight synchronization primitive used to constrain concurrent entry to a shared useful resource. When either would suffice, a semaphore might be extra effective than the usual condition variable. Outlined in header

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