Detailed Description

Used to pass results of asynchronous device calls back to the calling client.

Objects of this class serve as one-time disposable containers for the operation results. An rdaResult object is created by RDA and passed (by pointer) in the result parameter of each asynchronous device call (see "Asynchronous calls" in the rdaDeviceServerBase class). When the call results are ready, they can be reported to the client by invoking the appropriate return method on the object. All return calls put the specified value or error into the result container, send it to the client, and "dispose" the container. All return calls invalidate the result pointer; that is, each rdaResult object can be used only once to deliver a single operation result.
