Glib: g_tree_foreach and GTransverseFunc questions.

[Lucas Brasilino <brasilino prrr mpf gov br>]

Hi!

I'm writing a little daemon which I'm storing
user login and IP address as key and value pair
respectively, which I malloc()ed buffers for both,
using Balanced Binary Tree interface
from Glib 2.6.4. I'm using FC4. Eventually I compile
it with Glib 2.4.8 in a FC3 box.

I'm creating a tree with g_tree_new() and destroying
it with g_tree_destroy(). But before destroying it
I'm tranversing the entire tree with g_tree_foreach()
and free()ing both key and value.

It seems to work fine, since valgrind tells there's
no memory leak.
But I have no idea what user_data argument is used for
within g_tree_foreach() neither data argument of
GTransverseFunc. Any explanation ?

I've made user_data as NULL and did't touch
GTransverseFunc's data argument:

g_tree_foreach (SIConfig->tree, freeKeyData, NULL);

gboolean
freeKeyData (gpointer key, gpointer value, gpointer data)
{
  free (key);
  free (data);

  return FALSE;
}

It works.. :) but...

thanks a lot in advance
