Frees the nodes owned by a tree, but doesn’t free the tree itself.
void rbtree_free_resources(RBTree* tree);
| Name | Type | Description |
|---|---|---|
| tree | RBTree* | A pointer to the tree. |
Unlike the other *_free_resources functions, this should not be used to free any tree’s resources. It should only be used if the nodes owned by the tree were dynamically allocated in way that can be freed (e.g. with rbtree_add, or some user allocation method).
RBTREE_DEFINE_H(ISTree, is_tree, int, char*)
RBTREE_DEFINE_C(ISTree, is_tree, int, char*, int_cmp) // The definition of int_cmp can be found in the RedBlackTree main page.
ISTree tree;
is_tree_init(&tree);
is_tree_add(&tree, 0, "zero");
is_tree_add(&tree, 1, "one");
// Use the tree...
// Free the nodes owned by the tree, but don't
// free the tree itself because it exists on the stack.
