LINKED_DEVICE structure (dispmprt.h)

  • Article

The LINKED_DEVICE structure holds information that describes a linked display adapter configuration.

Syntax

typedef struct _LINKED_DEVICE {
  ULONG   ChainUid;
  ULONG   NumberOfLinksInChain;
  BOOLEAN LeadLink;
} LINKED_DEVICE, *PLINKED_DEVICE;

Members

ChainUid

A unique identifier for this chain of display adapters.

NumberOfLinksInChain

The expected number of linked adapters that the operating system should enumerate.

LeadLink

A value that indicates the leading link in the chain of linked adapters. The value is TRUE only for the adapter that will be allowed to enumerate child adapters. Otherwise, the value is FALSE.

Remarks

Prior to a call to DxgkDdiLinkDevice, the display miniport driver should fill the LINKED_DEVICE structure with information about the linked adapter configuration.
