DXGKDDI_QUERYVIDPNHWCAPABILITY callback function

Description

The DxgkDdiQueryVidPnHWCapability function requests that the display miniport driver report the capabilities of the hardware on a functional VidPn path.

Parameters

i_hAdapter [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]

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.
