DXGKCB_QUERYVIDPNINTERFACE callback function

Description

DXGKCB_QUERYVIDPNINTERFACE obtains a pointer to a DXGK_VIDPN_INTERFACE structure, which contains pointers to functions that the display miniport driver can call to inspect and alter a VidPN object.

Parameters

hVidPn [in]

A handle to a VidPN object. The VidPN manager previously provided the display miniport driver with this handle by calling DxgkDdiEnumVidPnCofuncModality, DxgkDdiIsSupportedVidPn, or DxgkDdiRecommendFunctionalVidPn.

VidPnInterfaceVersion [in]

A DXGK_VIDPN_INTERFACE_VERSION enumerator that specifies the version of the VidPN interface being requested. Callers must set this parameter to DXGK_VIDPN_INTERFACE_VERSION_V1.

ppVidPnInterface [out]

A pointer to a variable that receives a pointer to the DXGK_VIDPN_INTERFACE structure.

Return value

DxgkCbQueryVidPnInterface returns one of the following values:

Return code Description
STATUS_SUCCESS The function succeeded.
STATUS_INVALID_PARAMETER The value passed to ppVidPnInterface is not valid.
STATUS_GRAPHICS_INVALID_VIDPN The handle passed to hVidPn is not valid.
STATUS_NOT_SUPPORTED The interface version specified by VidPnInterfaceVersion is not supported.

Remarks

DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, the kernel-mode driver calls DxgkCbQueryVidPnInterface via the DXGKRNL_INTERFACE.
