The returnParameter is not a data member of the CDM message structure [see CDMMessageStruct]. However, CDMs supporting this function are required to provide the data specified by returnParameter. The Media Manager passes this value on to the application, and the CDM passes this value to the Media Manager as an input parameter to CDI_Complete_Message.
