LINKED_DEVICE structure (dispmprt.h)
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.
