+ * Double Linked List Macros
+ * -----------------------------------------------------------------------------
+ *
+ * All dll operations must be performed on a pre-initialized node.
+ * Inserting an uninitialized node into a list effectively initialized it.
+ *
+ * When a node is deleted from a list, you may initialize it to avoid corruption
+ * incurred by double deletion. You may skip initialization if the node is
+ * immediately inserted into another list.
+ *
+ * By placing a dll_t element at the start of a struct, you may cast a dll_t *
+ * to the struct or vice versa.
+ *
+ * Example of declaring an initializing someList and inserting nodeA, nodeB
+ *
+ * typedef struct item {
+ * dll_t node;
+ * int someData;
+ * } Item_t;
+ * Item_t nodeA, nodeB, nodeC;
+ * nodeA.someData = 11111, nodeB.someData = 22222, nodeC.someData = 33333;
+ *
+ * dll_t someList;
+ * dll_init(&someList);
+ *
+ * dll_append(&someList, (dll_t *) &nodeA);
+ * dll_prepend(&someList, &nodeB.node);
+ * dll_insert((dll_t *)&nodeC, &nodeA.node);
+ *
+ * dll_delete((dll_t *) &nodeB);
+ *
+ * Example of a for loop to walk someList of node_p
+ *
+ * extern void mydisplay(Item_t * item_p);
+ *
+ * dll_t * item_p, * next_p;
+ * for (item_p = dll_head_p(&someList); ! dll_end(&someList, item_p);
+ * item_p = next_p)
+ * {
+ * next_p = dll_next_p(item_p);
+ * ... use item_p at will, including removing it from list ...
+ * mydisplay((PItem_t)item_p);
+ * }
