  HRESULT        ReturnCode;
} D3DAUTHENTICATEDCHANNEL_QUERY_OUTPUT;

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.
