No synchronization is performed on *this alone. Concurrently calling join() on a similar thread object from numerous threads constitutes a knowledge race that leads to undefined behavior.

the connected thread completion synchronizes-While using the profitable return from the first operate that is waiting around over the shared state, or Along with the return of the last operate that releases the shared point out, whichever comes initially.

The regular library supplies facilities to get values which have been returned and to catch exceptions which have been thrown by asynchronous jobs (i.e. features released in separate threads). These values are communicated in the shared point out, during which the asynchronous undertaking might produce its return value or retailer an exception, and which can be examined, waited for, and or else manipulated by other threads that maintain occasions of std::long term or std::shared_future that reference that shared condition. Described in header

Gives a touch into the implementation to reschedule the execution of threads, permitting other threads to operate.

The mutex class is actually a synchronization primitive which can be utilized to guard shared knowledge from staying at the same time accessed by multiple threads.

blocks the current thread until finally the issue variable is awakened or until eventually specified time place has long been reached (public member function) [edit] Native manage

A clock is made of a place to begin (or epoch) plus a tick level. One example is, a clock could possibly have an epoch of January one, 1970 and tick each and every second. C++ defines several clock styles: Described in header Outlined in namespace std::chrono

In any case, the operate also could watch for longer than right until immediately after abs_time has become attained because of scheduling or resource rivalry delays.

This function may Stages of sleep perhaps block for more time than timeout_duration because of scheduling or useful resource competition delays.

No two std::thread objects may perhaps symbolize the same thread of execution; std::thread will not be CopyConstructible or CopyAssignable, although it is MoveConstructible and MoveAssignable.

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