Oh, right. I was looking at the code and it starts looking as something
else than C sometimes. Thanks for "waking me up" :)

Thanks, but I have to look inside this one, anyway.  You confirmed me
what I thought this is what the function is doing, but I saw no need for
cast in here.  Now I see it has to be changed from InterfaceNetwork to
Interface.  I guess this is some kind of polymorphism/inheritance design
in glib.

As I said before, I'm not very familiar with glib (and similar), I just
wanted to check Michal's code and give it some attention :)

Have a nice day,
