This overload might be employed to ignore spurious awakenings whilst watching for a particular ailment to become real.

remaining - pointer to the item to put the remaining time on interruption. May be NULL, where scenario it's disregarded

Mutual exclusion algorithms prevent several threads from at the same time accessing shared resources. This stops knowledge races and presents help for synchronization involving threads. Defined in header

Waits for the result to be available. Blocks until finally specified timeout_duration has elapsed or The end result results in being accessible, whichever arrives to start with. The return value identifies the state of the result.

Even though the clock in use is std::chrono::steady_clock or One more monotonic clock, a process clock adjustment may well induce a spurious wakeup.

Constant Rationalization future_status::deferred The shared point out incorporates a deferred functionality applying lazy analysis, so The end result are going to be computed only when explicitly asked for future_status::Completely ready The end result is prepared future_status::timeout The timeout has expired [edit] Exceptions

This overload could be used to disregard spurious awakenings when looking forward to a particular condition to be real.

This operate may possibly block for more time than sleep_duration resulting from scheduling or source contention delays.

duration and remaining may perhaps position at the same item, which simplifies re-operating the purpose after a sign.

A semaphore is a light-weight synchronization primitive used to constrain concurrent entry to a shared useful resource. When either would suffice, a semaphore could be additional efficient than a ailment variable. Defined in header

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