DXGK_CHILD_DEVICE_TYPE enumeration

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  = 0,
  TypeVideoOutput    = 1,
  TypeOther          = 2
} 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.

Remarks

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

For more information about child devices of display adapters, see Child Devices of the Display Adapter and Enumerating Child Devices of a Display Adapter.
