future::wait_until

 

template< class Clock, class Duration > std::future_status wait_until( const std::chrono::time_point<Clock,Duration>& timeout_time );

Waits for the result to become available. Blocks until specified timeout_time has been reached or the result becomes available, whichever comes first. Returns value identifies the state of the result. May block for longer than until timeout_time has been reached.

Parameters

timeout_time

-

maximum time point to block until

Return value

Constant	Explanation
future_status::deferred	The function to calculate the result has not been started yet
future_status::ready	The result is ready
future_status::timeout	The timeout has expired
