- * 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.
