The behavior is undefined if ex is null. 2) Creates a shared state of type T that is immediately ready and stores an exception pointer created from ex, then return a future associated with that shared state, as if by promise<T> p; p.set_exception(std::make_excep- tion_ptr(ex)); return p.get_future(); Return value A future object associated with the shared state that was created.
