shared_future Class

Describes an asynchronous return object. In contrast with a future object, an asynchronous provider can be associated with any number of shared_future objects.

template<class Ty>
class shared_future;

Remarks

Do not call any methods other than valid, operator=, and the destructor on a shared_future object that's empty.

shared_future objects are not synchronized. Calling methods on the same object from multiple threads introduces a data race that has unpredictable results.
