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 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 simple queue is headed by a pair of pointers, one the head of the ++ * list and the other to the tail of the list. The elements are singly ++ * linked to save space, so elements can only be removed from the ++ * head of the list. 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. A simple queue 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. ++ * ++ * A circle 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 circle queue may be traversed in either direction, but has a more ++ * complex end of list detection. ++ * ++ * For details on the use of these macros, see the queue(3) manual page. ++ */ ++ ++/* ++ * List definitions. ++ */ ++#define LIST_HEAD(name, type) \ ++struct name { \ ++ struct type *lh_first;
