-.Sh DESCRIPTION
-These macros define and operate on four types of data structures:
-singly-linked lists, singly-linked tail queues, lists, and tail queues.
-All four structures support the following functionality:
-.Bl -enum -compact -offset indent
-.It
-Insertion of a new entry at the head of the list.
-.It
-Insertion of a new entry after any element in the list.
-.It
-O(1) removal of an entry from the head of the list.
-.It
-Forward traversal through the list.
-.It
-Swawpping the contents of two lists.
-.El
-.Pp
-Singly-linked lists are the simplest of the four data structures
-and support only the above functionality.
-Singly-linked lists are ideal for applications with large datasets
-and few or no removals,
-or for implementing a LIFO queue.
-Singly-linked lists add the following functionality:
-.Bl -enum -compact -offset indent
-.It
-O(n) removal of any entry in the list.
-.El
-.Pp
-Singly-linked tail queues add the following functionality:
-.Bl -enum -compact -offset indent
-.It
-Entries can be added at the end of a list.
-.It
-O(n) removal of any entry in the list.
-.It
-They may be concatenated.
-.El
-However:
-.Bl -enum -compact -offset indent
-.It
-All list insertions must specify the head of the list.
-.It
-Each head entry requires two pointers rather than one.
-.It
-Code size is about 15% greater and operations run about 20% slower
-than singly-linked lists.
-.El
-.Pp
-Singly-linked tailqs are ideal for applications with large datasets and
-few or no removals,
-or for implementing a FIFO queue.
-.Pp
-All doubly linked types of data structures (lists and tail queues)
-additionally allow:
-.Bl -enum -compact -offset indent
-.It
-Insertion of a new entry before any element in the list.
-.It
-O(1) removal of any entry in the list.
-.El
-However:
-.Bl -enum -compact -offset indent
-.It
-Each element requires two pointers rather than one.
-.It
-Code size and execution time of operations (except for removal) is about
-twice that of the singly-linked data-structures.
-.El
-.Pp
-Linked lists are the simplest of the doubly linked data structures and support
-only the above functionality over singly-linked lists.
-.Pp
-Tail queues add the following functionality:
-.Bl -enum -compact -offset indent
-.It
-Entries can be added at the end of a list.
-.It
-They may be traversed backwards, from tail to head.
-.It
-They may be concatenated.
-.El
-However:
-.Bl -enum -compact -offset indent
-.It
-All list insertions and removals must specify the head of the list.
-.It
-Each head entry requires two pointers rather than one.
-.It
-Code size is about 15% greater and operations run about 20% slower
-than singly-linked lists.
-.El
-.Pp
-In the macro definitions,
-.Fa TYPE
-is the name of a user defined structure,
-that must contain a field of type
-.Li SLIST_ENTRY ,
-.Li STAILQ_ENTRY ,
-.Li LIST_ENTRY ,
-or
-.Li TAILQ_ENTRY ,
-named
-.Fa NAME .
-The argument
-.Fa HEADNAME
-is the name of a user defined structure that must be declared
-using the macros
-.Li SLIST_HEAD ,
-.Li STAILQ_HEAD ,
-.Li LIST_HEAD ,
-or
-.Li TAILQ_HEAD .
-See the examples below for further explanation of how these
-macros are used.
-.Sh SINGLY-LINKED LISTS
-A singly-linked list is headed by a structure defined by the
-.Nm SLIST_HEAD
-macro.
-This structure contains a single pointer to the first element
-on the list.
-The elements are singly linked for minimum space and pointer manipulation
-overhead at the expense of O(n) removal for arbitrary elements.
-New elements can be added to the list after an existing element or
-at the head of the list.
-An
-.Fa SLIST_HEAD
-structure is declared as follows:
-.Bd -literal -offset indent
-SLIST_HEAD(HEADNAME, TYPE) head;
-.Ed
-.Pp
-where
-.Fa HEADNAME
-is the name of the structure to be defined, and
-.Fa TYPE
-is the type of the elements to be linked into the list.
-A pointer to the head of the list can later be declared as:
-.Bd -literal -offset indent
-struct HEADNAME *headp;
-.Ed
-.Pp
-(The names
-.Li head
-and
-.Li headp
-are user selectable.)
-.Pp
-The macro
-.Nm SLIST_HEAD_INITIALIZER
-evaluates to an initializer for the list
-.Fa head .
-.Pp
-The macro
-.Nm SLIST_EMPTY
-evaluates to true if there are no elements in the list.
-.Pp
-The macro
-.Nm SLIST_ENTRY
-declares a structure that connects the elements in
-the list.
-.Pp
-The macro
-.Nm SLIST_FIRST
-returns the first element in the list or NULL if the list is empty.
-.Pp
-The macro
-.Nm SLIST_FOREACH
-traverses the list referenced by
-.Fa head
-in the forward direction, assigning each element in
-turn to
-.Fa var .
-.Pp
-The macro
-.Nm SLIST_FOREACH_SAFE
-traverses the list referenced by
-.Fa head
-in the forward direction, assigning each element in
-turn to
-.Fa var .
-However, unlike
-.Fn SLIST_FOREACH
-here it is permitted to both remove
-.Fa var
-as well as free it from within the loop safely without interfering with the
-traversal.
-.Pp
-The macro
-.Nm SLIST_INIT
-initializes the list referenced by
-.Fa head .
-.Pp
-The macro
-.Nm SLIST_INSERT_HEAD
-inserts the new element
-.Fa elm
-at the head of the list.
-.Pp
-The macro
-.Nm SLIST_INSERT_AFTER
-inserts the new element
-.Fa elm
-after the element
-.Fa listelm .
-.Pp
-The macro
-.Nm SLIST_NEXT
-returns the next element in the list.
-.Pp
-The macro
-.Nm SLIST_REMOVE_AFTER
-removes the element after
-.Fa elm
-from the list. Unlike
-.Fa SLIST_REMOVE ,
-this macro does not traverse the entire list.
-.Pp
-The macro
-.Nm SLIST_REMOVE_HEAD
-removes the element
-.Fa elm
-from the head of the list.
-For optimum efficiency,
-elements being removed from the head of the list should explicitly use
-this macro instead of the generic
-.Fa SLIST_REMOVE
-macro.
-.Pp
-The macro
-.Nm SLIST_REMOVE
-removes the element
-.Fa elm
-from the list.
-.Pp
-The macro
-.Nm SLIST_SWAP
-swaps the contents of
-.Fa head1
-and
-.Fa head2 .
-.Sh SINGLY-LINKED LIST EXAMPLE
-.Bd -literal
-SLIST_HEAD(slisthead, entry) head =
- SLIST_HEAD_INITIALIZER(head);
-struct slisthead *headp; /* Singly-linked List head. */
-struct entry {
- ...
- SLIST_ENTRY(entry) entries; /* Singly-linked List. */
- ...
-} *n1, *n2, *n3, *np;
-
-SLIST_INIT(&head); /* Initialize the list. */
-
-n1 = malloc(sizeof(struct entry)); /* Insert at the head. */
-SLIST_INSERT_HEAD(&head, n1, entries);
-
-n2 = malloc(sizeof(struct entry)); /* Insert after. */
-SLIST_INSERT_AFTER(n1, n2, entries);
-
-SLIST_REMOVE(&head, n2, entry, entries);/* Deletion. */
-free(n2);
-
-n3 = SLIST_FIRST(&head);
-SLIST_REMOVE_HEAD(&head, entries); /* Deletion from the head. */
-free(n3);
- /* Forward traversal. */
-SLIST_FOREACH(np, &head, entries)
- np-> ...
- /* Safe forward traversal. */
-SLIST_FOREACH_SAFE(np, &head, entries, np_temp) {
- np->do_stuff();
- ...
- SLIST_REMOVE(&head, np, entry, entries);
- free(np);
-}
-
-while (!SLIST_EMPTY(&head)) { /* List Deletion. */
- n1 = SLIST_FIRST(&head);
- SLIST_REMOVE_HEAD(&head, entries);
- free(n1);
-}
-.Ed
-.Sh SINGLY-LINKED TAIL QUEUES
-A singly-linked tail queue is headed by a structure defined by the
-.Nm STAILQ_HEAD
-macro.
-This structure contains a pair of pointers,
-one to the first element in the tail queue and the other to
-the last element in the tail queue.
-The elements are singly linked for minimum space and pointer
-manipulation overhead at the expense of O(n) removal for arbitrary
-elements.
-New elements can be added to the tail queue after an existing element,
-at the head of the tail queue, or at the end of the tail queue.
-A
-.Fa STAILQ_HEAD
-structure is declared as follows:
-.Bd -literal -offset indent
-STAILQ_HEAD(HEADNAME, TYPE) head;
-.Ed
-.Pp
-where
-.Li HEADNAME
-is the name of the structure to be defined, and

- * This file defines four types of data structures: singly-linked lists,
- * singly-linked tail queues, lists and tail queues.
- *
- * A singly-linked list is headed by a single forward pointer. The elements
- * are singly linked for minimum space and pointer manipulation overhead at
- * the expense of O(n) removal for arbitrary elements. New elements can be
- * added to the list after an existing element or at the head of the list.
- * Elements being removed from the head of the list should use the explicit
- * macro for this purpose for optimum efficiency. A singly-linked list may
- * only be traversed in the forward direction. Singly-linked lists are ideal
- * for applications with large datasets and few or no removals or for
- * implementing a LIFO queue.
- *
- * A singly-linked tail queue is headed by a pair of pointers, one to the
- * head of the list and the other to the tail of the list. The elements are
- * singly linked for minimum space and pointer manipulation overhead at the
- * expense of O(n) removal for arbitrary elements. New elements can be added
- * to the list after an existing element, at the head of the list, or at the
- * end of the list. Elements being removed from the head of the tail queue
- * should use the explicit macro for this purpose for optimum efficiency.
- * A singly-linked tail queue may only be traversed in the forward direction.
- * Singly-linked tail queues are ideal for applications with large datasets
- * and few or no removals or for implementing a FIFO queue.
- *
- * A list is headed by a single forward pointer (or an array of forward
- * pointers for a hash table header). The elements are doubly linked
- * so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before
- * or after an existing element or at the head of the list. A list
- * may only be traversed in the forward direction.
- *
- * A tail queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or
