No synchronization is done on *this alone. Concurrently contacting sign up for() on the same thread object from a number of threads constitutes a knowledge race that leads to undefined conduct.

This overload might be utilized to ignore spurious awakenings whilst awaiting a particular situation to become true.

The common recommends which the clock tied to sleep_time be utilised, by which circumstance adjustments of the clock can be taken under consideration. Hence, the period in the block is likely to be roughly than sleep_time - Clock::now() at some time of the call, dependant upon the path with the adjustment and whether it is honored with the implementation.

three) Registers *this for the length of the call, for being notified if a prevent request is created on stoken's involved quit-condition; it is actually then comparable to

The very best-stage functionality might talk its return price or an exception to your caller by using std::promise or by modifying shared variables (which may call for synchronization, see std::mutex and std::atomic).

blocks the current thread until finally the problem variable is awakened or right up until specified time place has long been arrived at (public member function) [edit] Native cope with

A clock consists of a starting point (or epoch) and also a tick fee. By way of example, a clock might have an epoch of January 1, 1970 and tick each next. C++ defines many clock varieties: Defined in header Defined in namespace std::chrono

The operate also might block until just after sleep_time has become attained because of system scheduling or useful resource competition delays.

This function may perhaps How sleep cycle works block for more time than sleep_duration because of scheduling or useful resource competition delays.

Note the destructors of std::futures obtained by usually means aside from a call to std::async under no circumstances block. [edit] Instance

This enables the functionality to check if cease has actually been asked for throughout its execution, and return if it's.

The end result or exception is put from the shared point out affiliated with the returned std::upcoming and only then it is actually made ready. All further accesses to the same std::long term will return the result immediately.
