List

C doubly linked list implementation.

API

ListNode *ListNode_new(void *val);

List *List_new();
ListNode *List_push(List *self, ListNode *node);
ListNode *List_unshift(List *self, ListNode *node);
ListNode *List_find(List *self, void *val);
void List_destroy(List *self);

ListIterator *ListIterator_new(List *list, ListDirection direction);
ListNode *ListIterator_next(ListIterator *self);
void ListIterator_destroy(ListIterator *self);

Examples

List iteration:

List *langs = List_new();

ListNode *c = List_push(langs, ListNode_new("c"));
ListNode *js = List_push(langs, ListNode_new("js"));
ListNode *ruby = List_push(langs, ListNode_new("ruby"));

ListIterator *it = ListIterator_new(langs, LIST_HEAD);
ListNode *node;
while ((node = ListIterator_next(it))) {
	puts(node->val);
}

ListIterator_destroy(it);
List_destroy(langs);

stdout:

c
js
ruby
