The DxgkDdiGetScanLine function determines whether the specified video present target of a video present network (VidPN) is in vertical blanking mode and retrieves the current scan line.

Parameters

hAdapter [in]

A pointer to a DXGKARG_GETSCANLINE structure that contains the vertical blanking status of a video present target.

DxgkDdiGetScanLine should be made pageable.
