Used in a call to the pfnCheckMultiPlaneOverlaySupport (D3D) function to check details on hardware support for multiplane overlays.
VidPnSourceId [in]The zero-based video present network (VidPN) source identification number of the input for which the hardware support is queried.
NumPlanes [out]The number of overlay planes that the hardware supports.
pPlanes [out]A pointer to a D3DDDI_CHECK_MULTIPLANE_OVERLAY_SUPPORT_PLANE_INFO structure that specifies support attributes that the hardware provides for multiplane overlays.
Supported [out]TRUE if the hardware supports multiplane overlays, otherwise FALSE.
