LIST_ENTRY structure (ntdef.h)
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.
