reflection for structs

[kani]

Hi all,

first execuse me if this question has been asked before. I am doing alot of 
C coding using emacs as my IDE, but i was wondering if there is a package 
or something to help with auto completion for stuct members. what is mean 
is: after you type the stuct name, instead of memorizing or looking up all 
the struct members, as soon as you type "name." emacs will give you the 
list of the struct members and you can choose the one you want.

thanx alot for any help or pointers.

thanx
mark
