Magazine Unload (0x001D - 0x0006)
Directs the CDM to inhibit the execution of any subsequent magazine messages until another magazine load message is received.
The following table lists return values and descriptions.
IMPORTANT:Mandatory for removables with 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 (0x0006) 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 to field the message.
The Magazine messages other than Magazine Load should be returned with a Magazine Not Present completion code.
