DxgkDdiQueryVidPnHWCapability routine
The DxgkDdiQueryVidPnHWCapability function requests that the display miniport driver report the capabilities of the hardware on a functional VidPn path.
Syntax
PDXGKDDI_QUERYVIDPNHWCAPABILITY DxgkDdiQueryVidPnHWCapability;
NTSTATUS APIENTRY DxgkDdiQueryVidPnHWCapability(
_In_ const HANDLE i_hAdapter,
_Inout_ DXGKARG_QUERYVIDPNHWCAPABILITY *io_pVidPnHWCaps
)
{ ... }
Parameters
- i_hAdapter [in]
-
[in] A handle to a context block associated with a display adapter. The display miniport driver previously provided this handle to the DirectX graphics kernel subsystem in the MiniportDeviceContext output parameter of the DxgkDdiAddDevice function.
- io_pVidPnHWCaps [in, out]
-
[in/out] A pointer to a DXGKARG_QUERYVIDPNHWCAPABILITY structure that describes the hardware capabilities of a functional VidPN.
Return value
DxgkDdiQueryVidPnHwCapability returns STATUS_SUCCESS if it succeeds; otherwise, it returns one of the error codes defined in Ntstatus.h.
Remarks
For more information on how to process this function, see Querying VidPN Hardware Capabilities.
DxgkDdiQueryInterface should be made pageable.
