  • Article

The DISPLAYCONFIG_TOPOLOGY_ID enumeration specifies the type of display topology.

Syntax

typedef enum DISPLAYCONFIG_TOPOLOGY_ID {
  DISPLAYCONFIG_TOPOLOGY_INTERNAL = 0x00000001,
  DISPLAYCONFIG_TOPOLOGY_CLONE = 0x00000002,
  DISPLAYCONFIG_TOPOLOGY_EXTEND = 0x00000004,
  DISPLAYCONFIG_TOPOLOGY_EXTERNAL = 0x00000008,
  DISPLAYCONFIG_TOPOLOGY_FORCE_UINT32 = 0xFFFFFFFF
} ;

Constants

 
DISPLAYCONFIG_TOPOLOGY_INTERNAL
Value: 0x00000001
Indicates that the display topology is an internal configuration.
DISPLAYCONFIG_TOPOLOGY_CLONE
Value: 0x00000002
Indicates that the display topology is clone-view configuration.
DISPLAYCONFIG_TOPOLOGY_EXTEND
Value: 0x00000004
Indicates that the display topology is an extended configuration.
DISPLAYCONFIG_TOPOLOGY_EXTERNAL
Value: 0x00000008
Indicates that the display topology is an external configuration.
DISPLAYCONFIG_TOPOLOGY_FORCE_UINT32
Value: 0xFFFFFFFF
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. You should not use this value.
