AVL C Library

This data structure features fast (O(log N)) insertion, removal, and retrieval of records, provided that there is a sorting relation over their keys and there are no entries with equal keys. The AVL tree is an explicit binary searching tree, where left children of each vertex are less or equal, while right children are greater or equal than the vertex itself. In addition, the tree is balanced so that the difference between the depths of the two subtrees of each vertex is at most one.

Searching?

Nice, handy library.

How do you search for a node? The search function appears to return only integers:

int avl_search(avl_tree* t, avl* a,int(*iter)(avl* a));
