ULONG cbRequestedInformationSize;
BYTE abRequestedInformation[4076];
} OPM_REQUESTED_INFORMATION;
Members
omac
An OPM_OMAC structure that contains a Message Authentication Code (MAC) of the status data. The driver will use AES-based one-key CBC MAC (OMAC) to calculate this value.
cbRequestedInformationSize
The size of the valid data in the abRequestedInformation member, in bytes.
abRequestedInformation[4076]
A buffer that contains the result of the status request. The meaning of the data depends on the status request. For more information, see OPM Status Requests.
Remarks
The layout of this structure is identical to the AMCOPPStatusOutput structure used in Certified Output Protection Protocol (COPP).
