The pfnCreateNewPathInfo function returns a pointer to a D3DKMDT_VIDPN_PRESENT_PATH structure that the display miniport driver populates before calling pfnAddPath.

Parameters

hVidPnTopology [in]

A handle to a VidPN topology object. The display miniport driver previously obtained this handle by calling the pfnGetTopology function of the DXGK_VIDPN_INTERFACE interface.

ppNewVidPnPresentPathInfo [out]

A pointer to a variable that receives a pointer to a D3DKMDT_VIDPN_PRESENT_PATH structure allocated by the VidPN manager.

Return value

The pfnCreateNewPathInfo function returns one of the following values:

Return code Description
STATUS_SUCCESS The function succeeded.
STATUS_GRAPHICS_INVALID_VIDPN_TOPOLOGY The handle supplied in hVidPnTopology was invalid.

Remarks

After you call pfnCreateNewPathInfo to obtain a D3DKMDT_VIDPN_PRESENT_PATH structure, you must do one, but not both, of the following:

The D3DKMDT_HVIDPNTOPOLOGY data type is defined in D3dkmdt.h.
