* This file contains macros to manipulate singly and doubly-linked lists.
*
* 1. LL_ macros: singly-linked lists.
* 2. DL_ macros: doubly-linked lists.
* 3. CDL_ macros: circular doubly-linked lists.
*
* To use singly-linked lists, your structure must have a "next" pointer.
* To use doubly-linked lists, your structure must "prev" and "next" pointers.
* Either way, the pointer to the head of the list must be initialized to NULL.
*
* ----------------.EXAMPLE -------------------------
* struct item {
* int id;
* struct item *prev, *next;
* }
*
* struct item *list = NULL:
*
* int main() {
* struct item *item;
* ... allocate and populate item ...
* DL_APPEND(list, item);
* }
* --------------------------------------------------
*
* For doubly-linked lists, the append and delete macros are O(1)
* For singly-linked lists, append and delete are O(n) but prepend is O(1)
* The sort macro is O(n log(n)) for all types of single/double/circular lists.
