|
* 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.
|
||||||
|
*
|
||||||
|
* For details on the use of these macros, see the queue(3) manual page.
