future<void> make_ready_future(); |
(2) | (concurrency TS) |
1) If std::decay_t<T> is std::reference_wrapper<X>, then the type V is X&, otherwise, V is std::decay_t<T>.
Creates a shared state of type V that is immediately ready, with the result constructed from std::forward<T>(value), then returns a std::experimental::future associated with that shared state.
2) Creates a shared state of type void that is immediately ready, then returns a std::experimental::future associated with that shared state.
Return value
A std::experimental::future associated with the shared state that is created.
