This overload could possibly be made use of to ignore spurious awakenings while watching for a particular situation to be real.

remaining - pointer to the object To place the remaining time on interruption. Might be NULL, where situation it is actually dismissed

Mutual exclusion algorithms protect against multiple threads from concurrently accessing shared resources. This stops knowledge races and offers assistance for synchronization amongst threads. Described in header

The best-amount perform 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).

Even when the clock in use is std::chrono::steady_clock or An additional monotonic clock, a method clock adjustment could induce a spurious wakeup.

Frequent Explanation future_status::deferred The shared state contains a Stages of sleep deferred function using lazy analysis, so The end result are going to be computed only when explicitly asked for future_status::Completely ready The result is ready future_status::timeout The timeout has expired [edit] Exceptions

This overload may be applied to ignore spurious awakenings though looking ahead to a certain problem to be real.

This purpose might block for for a longer period than sleep_duration because of scheduling or source contention delays.

period and remaining could issue at precisely the same object, which simplifies re-managing the function following a sign.

A semaphore is a light-weight synchronization primitive used to constrain concurrent use of a shared useful resource. When either would suffice, a semaphore is often more productive than the usual condition variable. Outlined in header

In case the purpose file returns a worth or throws 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
