DXGK_CHILD_DEVICE_TYPE enumeration (dispmprt.h)

  • Article

The DXGK_CHILD_DEVICE_TYPE enumeration is used to indicate the type of a child device of the display adapter.

Syntax

typedef enum _DXGK_CHILD_DEVICE_TYPE {
  TypeUninitialized,
  TypeVideoOutput,
  TypeOther,
  TypeIntegratedDisplay
} DXGK_CHILD_DEVICE_TYPE, *PDXGK_CHILD_DEVICE_TYPE;

Constants

 
TypeUninitialized
Indicates that a variable of type DXGK_CHILD_DEVICE_TYPE has not yet been assigned a meaningful value.
TypeVideoOutput
Indicates that the child device is a video output. A video output is the circuitry on the display adapter that supplies a video signal to an external or integrated monitor (or other display device). Note that monitors, integrated LCD panels, and other devices that actually display an image are not considered child devices of the display adapter.
TypeOther
Indicates that the child device is not a video output. TV tuners, crossbar switches, and MPEG2 codecs are examples of child devices that are not video outputs.
TypeIntegratedDisplay
Type indicating that this target is permanently connected to an integrated display.

Remarks

The ChildDeviceType member of a DXGK_CHILD_DESCRIPTOR structure is a DXGK_CHILD_DEVICE_TYPE value.
