No synchronization is done on *this by itself. Concurrently calling join() on the same thread item from many threads constitutes an information race that results in undefined actions.

std::launch::deferred or has supplemental bits established, it's going to fall again to deferred invocation or perhaps the implementation-defined insurance policies In such a case.
remaining - pointer to the item to put the remaining time on interruption. May very well be NULL, during which case it truly is ignored
Regardless of whether the shared variable is atomic, it must be modified although possessing the mutex to properly publish the modification to the waiting thread.
The top-degree operate may well connect its return value or an exception for the caller by means of std::guarantee or by modifying shared variables (which can require synchronization, see std::mutex and std::atomic).
The typical endorses which the clock tied to abs_time be utilized to evaluate time; that clock is not required to be considered a monotonic clock. There aren't any guarantees regarding the conduct of this perform In the event the clock is modified discontinuously, but the present implementations change abs_time from Clock to std::chrono::system_clock and delegate to POSIX pthread_cond_timedwait so the wait around honors adjustments for the program clock, but not on the consumer-presented Clock.
Regardless of whether notified underneath lock, overload (one) can make no ensures in regards to the condition on the connected predicate when returning as a result of timeout.

If the longer term is the result of a call to std::async that applied lazy Stages of sleep analysis, this operate returns straight away with no waiting.

Blocks the execution of the current thread for a minimum of right until the TIME_UTC primarily based length pointed to by period has elapsed.
This allows the perform to examine if prevent has been requested for the duration of its execution, and return if it's got.
If the std::potential received from std::async will not be moved from or sure to a reference, the destructor from the std::potential will block at the conclusion of the entire expression until the asynchronous operation completes, primarily generating code which include the following synchronous:
