Description Christian Neumair 2006-06-03 09:19:40 UTC 
g_object_set_data_full ignores the passed-in destroy notify if the data parameter is NULL, but the docs don't state that.

Maybe the destroy parameter docs should be:

@destroy: function to call when the association is destroyed. Ignored if @data is %NULL.
Comment 1 Matthias Clasen 2006-06-04 02:03:27 UTC 
what did you expect g_object_set_data_full (NULL,...) to
do with the destroy notify ?
Comment 2 Christian Neumair 2006-06-04 12:09:43 UTC 
I mean

 g_object_set_data_full (object, "key", NULL, g_free);

The effect of the following call is undefined of course:

 g_object_set_data_full (NULL, "key", data, g_free);
