returnParameter

If a space function was requested, the number of set marks spaced over is returned in this field.

The returnParameter is not a data member of the CDM message structure [seeCDMMessageStruct]. 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.
