DXGK_DIAG_DISPLAY_LID_STATE enumeration (dispmprt.h)

  • Article

DXGK_DIAG_DISPLAY_LID_STATE provides the lid state of the target to the operating system (OS) when it is gathering nonintrusive display diagnostic information.

Syntax

typedef enum _DXGK_DIAG_DISPLAY_LID_STATE {
  DXGK_DIAG_DISPLAY_LID_STATE_UNINITIALIZED,
  DXGK_DIAG_DISPLAY_LID_STATE_NOTAPPLICABLE,
  DXGK_DIAG_DISPLAY_LID_STATE_OPEN,
  DXGK_DIAG_DISPLAY_LID_STATE_CLOSE,
  DXGK_DIAG_DISPLAY_LID_STATE_UNKNOWN
} DXGK_DIAG_DISPLAY_LID_STATE;

Constants

 
DXGK_DIAG_DISPLAY_LID_STATE_UNINITIALIZED
Reserved for OS use during diagnostic initialization.
DXGK_DIAG_DISPLAY_LID_STATE_NOTAPPLICABLE
Lid state is not applicable on this target. This would be the value used for most of the targets which are not internal displays.
DXGK_DIAG_DISPLAY_LID_STATE_OPEN
The lid of the display is currently open, according to driver state.
DXGK_DIAG_DISPLAY_LID_STATE_CLOSE
The lid of the display is currently closed, according to driver state.
DXGK_DIAG_DISPLAY_LID_STATE_UNKNOWN
The driver does not know the current lid state. A driver should only use this value when it doesn't maintain/cache lid state internally.

Remarks

The DXGK_DIAG_DISPLAY_LID_STATE enumeration is a member of the DXGK_DISPLAYSTATE_NONINTRUSIVE structure. It is used while gathering display diagnostic information via calls to DxgkDdiGetDisplayStateNonIntrusive.

DXGK_DIAG_DISPLAY_LID_STATE is only applicable to form factors which have a lid. If the driver caches the current state of the lid (open or close) then we want to compare it against to OS state.
