DXGK_DP_INTERFACE structure (dispmprt.h)

A kernel-mode component that needs to use the DXGK_DP_INTERFACE DisplayPort (DP) interface calls the display miniport driver's DxgkDdiQueryInterface function.

Syntax

typedef struct _DXGK_DP_INTERFACE {
  IN USHORT                        Size;
  IN USHORT                        Version;
  OUT PVOID                        Context;
