pointer scope issues

[Najati R Imam <nrimam0 pop uky edu>]

I've recently started playing around with gtk and in the two things I've tried
to do I think I've come across the same problem. I'll use the second as my
example:

I set up a struct node that contains a data variable and a prev and next
pointers to other node and a pointer to the widget that I need to modify. its a
really simple 2xlinked list class that, but thats all I need and I've written a
hundread of these thing and am positive I'm doing it right. But it seems that
whenever I call the callback the makes a new one (at the "clicked" of a button)
it goes and makes the new one, sets it up right and advanced the current
pointer (which I am passing as the user data in the callback) and then when it
leaves it forgets it.

So it seems pretty obvious to me that the scope on my user data (current) isn't
right but I can't find anything that should work more then what I have that
doesn't segfault. Is there something funny with callbacks that I wouldn't know
from plains old c/c++ scope?
