LIST_ENTRY structure (ntdef.h)

  • Article

A LIST_ENTRY structure describes an entry in a doubly linked list or serves as the header for such a list.

Syntax

typedef struct _LIST_ENTRY {
  struct _LIST_ENTRY *Flink;
  struct _LIST_ENTRY *Blink;
} LIST_ENTRY, *PLIST_ENTRY, PRLIST_ENTRY;

Members

Flink

For a LIST_ENTRY structure that serves as a list entry, the Flink member points to the next entry in the list or to the list header if there is no next entry in the list.

For a LIST_ENTRY structure that serves as the list header, the Flink member points to the first entry in the list or to the LIST_ENTRY structure itself if the list is empty.

Blink

For a LIST_ENTRY structure that serves as a list entry, the Blink member points to the previous entry in the list or to the list header if there is no previous entry in the list.

For a LIST_ENTRY structure that serves as the list header, the Blink member points to the last entry in the list or to the LIST_ENTRY structure itself if the list is empty.

Remarks

A LIST_ENTRY structure that describes the list head must have been initialized by calling InitializeListHead.

A driver can access the Flink or Blink members of a LIST_ENTRY, but the members must only be updated by the system routines supplied for this purpose.

For more information about how to use LIST_ENTRY structures to implement a doubly linked list, see Singly and Doubly Linked Lists.
