No synchronization is executed on *this itself. Concurrently contacting be part of() on the identical thread object from various threads constitutes an information race that results in undefined actions.

If plan is std::start::async
remaining - pointer to the item To place the remaining time on interruption. Could possibly be NULL, in which scenario it's overlooked
Mutual exclusion algorithms avoid many threads from simultaneously accessing shared sources. This stops details races and offers assist for synchronization concerning threads. Defined in header
Waits for the result to become accessible. Blocks until finally specified timeout_duration has elapsed or the result gets offered, whichever will come initially. The return benefit identifies the point out of The end result.
Whether or not the clock in use is std::chrono::steady_clock or A different monotonic clock, a process Tips to improve your sleep routine clock adjustment may perhaps induce a spurious wakeup.
Continual Clarification future_status::deferred The shared condition includes a deferred perform making use of lazy evaluation, so the result will probably be computed only when explicitly requested future_status::ready The result is ready 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 operate might block for for a longer period than sleep_duration on account of scheduling or resource rivalry delays.
period and remaining may well level at a similar object, which simplifies re-running the operate after a sign.
std::start::deferred.

Threads start out execution immediately upon development of your related thread object (pending any OS scheduling delays), starting off at the top-degree operate delivered as a constructor argument. The return value of the highest-amount function is ignored and if it terminates by throwing an exception, std::terminate is referred to as.
std::condition_variable is often a synchronization primitive made use of which has a std::mutex to dam one or more threads until finally One more thread equally modifies a shared variable (the affliction) and notifies the std::condition_variable.
