1) Creates a shared state of type
T
that is immediately ready and stores the exception pointer ex, then return a future associated with that shared state, as if by promise<T> p; p.set_exception(ex); return p.get_future();. 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_exception_ptr (ex)); return p.get_future();.[edit] Return value
A future
object associated with the shared state that was created.
