Members
-
omac
-
A D3D_OMAC structure that contains a Message Authentication Code (MAC) of the data. The driver uses AES-based one-key CBC MAC (OMAC) to calculate this value for the block of data that appears after this structure member.
-
QueryType

A GUID that specifies the query. For a list of values, see Content Protection Queries.
-
HANDLE
-
A handle to the authenticated channel.
-
UINT
-
The query sequence number.
-
ReturnCode

The result code for the query.
Remarks
For the QueryType, hChannel, and SequenceNumber members, the driver uses in the same values that the application provided in the D3DAUTHENTICATEDCHANNEL_QUERY_INPUT structure. The application should verify that these values match.
