Tools for C Programming

[Chengqi(Lars) Song]

hi,

I've been using emacs for a long time but I've just started to write C program 
in emacs. I need some functions but dunno how to configure. Maybe you can give 
me some suggestions.

1. The folder structure is like:
   abc-+-
       |--MakeFile
       |--src-+-
              |--main.c
   after I use C-x C-f to open main.c, how to 'make' when the MakeFile is in 
the parent folder?

2. How to display function list?

3. How to auto-complete identifier names, struct memebers, and hints for 
function parameters?

4. How to jump to definition?

Thanks a lot!
