DXGKDDI_QUERYVIDPNHWCAPABILITY callback function (d3dkmddi.h)
The DxgkDdiQueryVidPnHWCapability function requests that the display miniport driver report the capabilities of the hardware on a functional VidPn path.
Syntax
DXGKDDI_QUERYVIDPNHWCAPABILITY DxgkddiQueryvidpnhwcapability;
NTSTATUS DxgkddiQueryvidpnhwcapability(
[in] IN_CONST_HANDLE i_hAdapter,
[in/out] INOUT_PDXGKARG_QUERYVIDPNHWCAPABILITY io_pVidPnHWCaps
)
{...}
Parameters
[in] i_hAdapter
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.
[in/out] io_pVidPnHWCaps
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.
