Remarks

When you use the register method on a cancellation_token to receive notification of when cancellation occurs, a cancellation_token_registration object is returned as a handle to the callback so that you can request a specific callback no longer be made through use of the deregister method.

The cancellation_token_registration behaves like a smart pointer and is safe and efficient to pass around by value.
