DXGK_BRIGHTNESS_INTERFACE structure (dispmprt.h)
The DXGK_BRIGHTNESS_INTERFACE structure contains pointers to functions in the Panel Brightness Control Interface, which is implemented by the display miniport driver.
Syntax
typedef struct {
IN USHORT Size;
IN USHORT Version;
OUT PVOID Context;
OUT PINTERFACE_REFERENCE InterfaceReference;
OUT PINTERFACE_DEREFERENCE InterfaceDereference;
OUT DXGK_BRIGHTNESS_GET_POSSIBLE GetPossibleBrightness;
OUT DXGK_BRIGHTNESS_SET SetBrightness;
OUT DXGK_BRIGHTNESS_GET GetBrightness;
} DXGK_BRIGHTNESS_INTERFACE, *PDXGK_BRIGHTNESS_INTERFACE;
Members
Size
The size, in bytes, of this structure.
Version
The version number of the brightness interface. Version number constants are defined in Dispmprt.h (for example, DXGK_BRIGHTNESS_INTERFACE_VERSION_1).
Context
A pointer to a private context block.
InterfaceReference
A pointer to an interface reference function that is implemented by the display miniport driver.
InterfaceDereference
A pointer to an interface dereference function that is implemented by the display miniport driver.
GetPossibleBrightness
A pointer to the display miniport driver's DxgkDdiGetPossibleBrightness function.
SetBrightness
A pointer to the display miniport driver's DxgkDdiSetBrightness function.
GetBrightness
A pointer to the display miniport driver's DxgkDdiGetBrightness function.
Remarks
A kernel-mode component that must use the brightness interface initiates a call to the display miniport driver's DxgkDdiQueryInterface function to retrieve the interface and passes GUID_DEVINTERFACE_BRIGHTNESS in the InterfaceType member of the QUERY_INTERFACE structure that the QueryInterface parameter points to.
