124 * This file defines five types of data structures: singly-linked lists,
125 * lists, simple queues, tail queues, and circular queues.
126 *
127 *
128 * A singly-linked list is headed by a single forward pointer. The elements
129 * are singly linked for minimum space and pointer manipulation overhead at
130 * the expense of O(n) removal for arbitrary elements. New elements can be
131 * added to the list after an existing element or at the head of the list.
132 * Elements being removed from the head of the list should use the explicit
133 * macro for this purpose for optimum efficiency. A singly-linked list may
134 * only be traversed in the forward direction. Singly-linked lists are ideal
135 * for applications with large datasets and few or no removals or for
136 * implementing a LIFO queue.
137 *
138 * A list is headed by a single forward pointer (or an array of forward
139 * pointers for a hash table header). The elements are doubly linked
140 * so that an arbitrary element can be removed without a need to
141 * traverse the list. New elements can be added to the list before
142 * or after an existing element or at the head of the list. A list
143 * may only be traversed in the forward direction.
144 *
145 * A simple queue is headed by a pair of pointers, one the head of the
146 * list and the other to the tail of the list. The elements are singly
147 * linked to save space, so elements can only be removed from the
148 * head of the list. New elements can be added to the list before or after
149 * an existing element, at the head of the list, or at the end of the
150 * list. A simple queue may only be traversed in the forward direction.
151 *
152 * A tail queue is headed by a pair of pointers, one to the head of the
153 * list and the other to the tail of the list. The elements are doubly
154 * linked so that an arbitrary element can be removed without a need to
155 * traverse the list. New elements can be added to the list before or
156 * after an existing element, at the head of the list, or at the end of
157 * the list. A tail queue may be traversed in either direction.
158 *
159 * A circle queue is headed by a pair of pointers, one to the head of the
160 * list and the other to the tail of the list. The elements are doubly
161 * linked so that an arbitrary element can be removed without a need to
162 * traverse the list. New elements can be added to the list before or after
163 * an existing element, at the head of the list, or at the end of the list.
164 * A circle queue may be traversed in either direction, but has a more
165 * complex end of list detection.
166 *
167 * For details on the use of these macros, see the queue(3) manual page.

30 * This file defines data structures for different types of trees:
31 * splay trees and red-black trees.
32 *
33 * A splay tree is a self-organizing data structure. Every operation
34 * on the tree causes a splay to happen. The splay moves the requested
35 * node to the root of the tree and partly rebalances it.
36 *
37 * This has the benefit that request locality causes faster lookups as
38 * the requested nodes move to the top of the tree. On the other hand,
39 * every lookup causes memory writes.
40 *
41 * The Balance Theorem bounds the total access time for m operations
42 * and n inserts on an initially empty tree as O((m + n)lg n). The
43 * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
44 *
45 * A red-black tree is a binary search tree with the node color as an
46 * extra attribute. It fulfills a set of conditions:
47 * - every search path from the root to a leaf consists of the
48 * same number of black nodes,
49 * - each red node (except for the root) has a black parent,
50 * - each leaf node is black.
51 *
52 * Every operation on a red-black tree is bounded as O(lg n).
53 * The maximum height of a red-black tree is 2lg (n+1).
