Presents a hint towards the implementation to reschedule the execution of threads, enabling other threads to run.

the linked thread completion synchronizes-Together with the profitable return from the primary purpose that is certainly waiting around within the shared state, or Using the return of the last function that releases the shared point out, whichever will come 1st.

The common recommends the clock tied to sleep_time be employed, wherein situation changes from the clock can be taken into account. Consequently, the duration with the block may be kind of than sleep_time - Clock::now() at the time of the decision, depending on the route of the adjustment and whether it is honored via the implementation.

A time place is a length of your time that has passed For the reason that epoch of a selected clock. Defined in header Outlined in namespace std::chrono

blocks The existing thread right until the condition variable is awakened or till specified time level has become achieved (general public member purpose) [edit] Indigenous tackle

Constant Explanation future_status::deferred The shared state contains a deferred operate applying lazy analysis, so The end result might be computed only when explicitly asked for future_status::All set The end result is prepared future_status::timeout The timeout has expired [edit] Exceptions

This overload could possibly be employed to ignore spurious awakenings though watching for a certain problem to become legitimate.

This purpose might block for longer than timeout_duration resulting from scheduling or source rivalry delays.

duration and remaining may possibly stage at the exact same object, which simplifies re-functioning the operate following a signal.

std::launch::deferred.

Threads commence execution promptly on construction on the affiliated thread object Stages of sleep (pending any OS scheduling delays), beginning at the highest-amount function offered being a constructor argument. The return price of the top-degree operate is overlooked and when it terminates by throwing an exception, std::terminate is known as.

std::condition_variable is a synchronization primitive used having a std::mutex to block one or more threads till An additional thread the two modifies a shared variable (the problem) and notifies the std::condition_variable.
