_DXGKARG_RECOMMENDFUNCTIONALVIDPN structure

Description

The DXGKARG_RECOMMENDFUNCTIONALVIDPN structure contains arguments for the DxgkDdiRecommendFunctionalVidPn function. The DxgkDdiRecommendFunctionalVidPn function creates a functional video present network (VidPN) that can be implemented on a specified display adapter.

Members

`NumberOfVidPnTargets`

Reserved for future use.

`pVidPnTargetPrioritizationVector`

Reserved for future use.

`hRecommendedFunctionalVidPn`

A handle, provided by the caller, to an empty VidPN object. DxgkDdiRecommendFunctionalVidPn must add a path (source-target pair) to the VidPN's topology and must pin modes on the path's source and target. For information about adding paths to a topology and creating mode sets for video present sources and targets, see VidPN Objects and Interfaces.

`RequestReason`

A DXGK_RECOMMENDFUNCTIONALVIDPN_REASON value that indicates why the caller is requesting a functional VidPN.

`pPrivateDriverData`

A pointer to a buffer that contains private data that is passed from a user-mode application to the display miniport driver.

`PrivateDriverDataSize`

The size, in bytes, of the data block pointed to by pPrivateDriverData.
