The pfnRemovePath function removes a video present path to a specified VidPN topology object.
Syntax
DXGKDDI_VIDPNTOPOLOGY_REMOVEPATH DxgkddiVidpntopologyRemovepath;
NTSTATUS DxgkddiVidpntopologyRemovepath(
IN_CONST_D3DKMDT_HVIDPNTOPOLOGY hVidPnTopology,
IN_CONST_D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId,
IN_CONST_D3DDDI_VIDEO_PRESENT_TARGET_ID VidPnTargetId
)
{...}
Parameters
hVidPnTopology

VidPnSourceId
[in] An integer that identifies a VidPN source path.
VidPnTargetId
[in] An integer that identifies a VidPN target path.
