Declaration [src] 

GTreeNode*
g_tree_replace_node (
  GTree* tree,
  gpointer key,
  gpointer value
)

Description [src]

Inserts a new key and value into a GTree similar to g_tree_insert_node(). The difference is that if the key already exists in the GTree, it gets replaced by the new key. If you supplied a value_destroy_func when creating the GTree, the old value is freed using that function. If you supplied a key_destroy_func when creating the GTree, the old key is freed using that function.

The tree is automatically ‘balanced’ as new key/value pairs are added, so that the distance from the root to every leaf is as small as possible.
