IOCTL_COPP_Status control code
Returns status on a protected video session.
Input Parameters
The VIDEO_REQUEST_PACKET (VRP) InputBuffer contains information passed from the display driver. For example, the display driver can pass a pointer to a COPP_IO_InputBuffer structure defined as follows:
typedef struct {
PVOID* ppThis;
PVOID InputBuffer;
HRESULT phr;
} COPP_IO_InputBuffer;
The ppThis member points to a pointer to the COPP DirectX VA device object on which status is retrieved. The InputBuffer member is set to a pointer to a DXVA_COPPStatusInput structure that contains information about the COPP status request. The phr member should be set to the value returned from the COPPQueryStatus function.
Output Parameters
The miniport driver returns a pointer to a DXVA_COPPStatusOutput structure in the VRP OutputBuffer. The DXVA_COPPStatusOutput structure contains the status.
I/O Status Block
The miniport driver sets the Information member of the STATUS_BLOCK structure to sizeof(DXVA_COPPStatusOutput).
