MFCONTENTPROTECTIONDEVICE_OUTPUT_DATA structure (mfidl.h)
Contains information about the data you received as output from a protection system function.
Syntax
typedef struct _MFCONTENTPROTECTIONDEVICE_OUTPUT_DATA {
DWORD PrivateDataByteCount;
DWORD MaxHWProtectionDataByteCount;
DWORD HWProtectionDataByteCount;
HRESULT Status;
LONGLONG TransportTimeInHundredsOfNanoseconds;
LONGLONG ExecutionTimeInHundredsOfNanoseconds;
BYTE OutputData[4];
} MFCONTENTPROTECTIONDEVICE_OUTPUT_DATA;
Members
PrivateDataByteCount
The size of the private data that the implementation of the security processor reserves, in bytes. You can determine this value by calling the IMFContentProtectionDevice::GetPrivateDataByteCount method.
MaxHWProtectionDataByteCount
The maximum size of data that the independent hardware vendor (IHV) can return in the output buffer, in bytes.
HWProtectionDataByteCount
The size of the data that the IHV wrote to the output buffer, in bytes.
Status
The result of the protection system function.
TransportTimeInHundredsOfNanoseconds
The number of 100 nanosecond units spent transporting the data.
ExecutionTimeInHundredsOfNanoseconds
The number of 100 nanosecond units spent running the protection system function.
OutputData[4]
The output of the protection system function.
If the value of the PrivateDataByteCount member is greater than 0, bytes 0 through PrivateDataByteCount - 1 are reserved for IHV use.
Bytes PrivateDataByteCount through MaxHWProtectionDataByteCount + PrivateDataByteCount - 1 contain the region
of the array into which the driver should return the output data from the protection system function.
The protection system specification defines the format and size of the
function.
