+ * 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.
+ */

+/* These macros use decltype or the earlier __typeof GNU extension.
