future Class
Describes an asynchronous return object.
template<class Ty>
class future;
Remarks
Each standard asynchronous provider returns an object whose type is an instantiation of this template. A future object provides the only access to the asynchronous provider that it is associated with. If you need multiple asynchronous return objects that are associated with the same asynchronous provider, copy the future object to a shared_future object.
