hi all,
is there any Open Source tool that i can use to list functions and
variables in a given source code tree (C, C++). there are times when i
want to know what functions are available and combined with cscope it
helps with better understanding of a project i learned.
i'm also interested on what tools u guys have been using all along
(other than emacs, vi, sed, etc) and in what way it helped. (btw, sorry
if it such a newbie question 

thanks for any help in advance.

CScope already gives you the information you want.  If you want a tool
with a lower overhead, running a version of ctags on a collection of
source code files will create a tags file listing every global variable,
function and structure definition.  You can also run nm on the compiled
object files to get similar information.
