DXGKDDI_VIDPN_ASSIGNMULTISAMPLINGMETHODSET callback function (d3dkmddi.h)

  • Artikel

The DXGKDDI_VIDPN_ASSIGNMULTISAMPLINGMETHODSET function assigns a set of multisampling methods to a particular video-present source in a specified VidPN.

Syntax

DXGKDDI_VIDPN_ASSIGNMULTISAMPLINGMETHODSET DxgkddiVidpnAssignmultisamplingmethodset;

NTSTATUS DxgkddiVidpnAssignmultisamplingmethodset(
  [in] IN_D3DKMDT_HVIDPN hVidPn,
  [in] IN_CONST_D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId,
  [in] IN_CONST_SIZE_T NumMethods,
  [in] const D3DDDI_MULTISAMPLINGMETHOD *pSupportedMethodSet
)
{...}

Parameters

[in] hVidPn

A handle to a VidPN object. The VidPN manager previously provided this handle to the display miniport driver by calling DxgkDdiEnumVidPnCofuncModality.

[in] VidPnSourceId

An integer that identifies one of the video present sources associated with the VidPN object.

[in] NumMethods

The number of elements in the pSupportedMethodSet array.

[in] pSupportedMethodSet

A pointer to an array of D3DDDI_MULTISAMPLINGMETHOD structures, each of which describes a multisampling method.

Return value

The DXGKDDI_VIDPN_ASSIGNMULTISAMPLINGMETHODSET function returns one of the following values.

Return code Description
STATUS_SUCCESS The function succeeded.
STATUS_GRAPHICS_INVALID_VIDPN The handle supplied in hVidPn was invalid.
STATUS_GRAPHICS_INVALID_VIDEO_PRESENT_SOURCE The identifier supplied in VidPnSourceId was invalid.
