Return Magazine Media Mapping (0x001D - 0x0002)
Directs the CDM to request the return of a structure that provides the slot mapping for a magazine device.
The following table lists return values and descriptions.
IMPORTANT:Mandatory for magazines.
This is a Media Manager control function [packaged in a CDMMessageStruct] that has 0x001D as the value in its function field to identify that it is a function in the magazine category. The value in parameter0 acts as a subfunction index (0x0002) to identify what function to perform. The CDM can either implement a secondary jump table using the value in parameter0 as an index or use a switch statement on parameter0 to call its routine that will field the message.
This message should not be issued until after the Return Magazine Info message is issued.
