||||
* 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 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. |
