++ * 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
++ * after an existing element, at the head of the list, or at the end of
++ * the list. A tail queue may be traversed in either direction.
++ *
++ * For details on the use of these macros, see the queue(3) manual page.
