Emacs auto-completing functions in C, etc

[oaul]

I love emacs. However, I can't remember the function declarations for many of the built-in C functions (ie those in stdio and stdlib headers)
In microsoft's ide for example, when you start typing a function, say "strtok", a little popup window shows the arguments that strtok takes. How can you do this in emacs? I have tried searching and im sorry if this has been asked thousands of times. I found something about TAGS but I think its a little cumbersome and overly complicated for what I am looking for. I saw something about a stupid Speedbar but i hate using a mouse. Someone help!

By the way - don't leave me hanging like this guy: http://www.linuxforums.org/forum/lin...ocomplete.html

Read up on this page: EmacsWiki: Cmode Addons

Emacswiki has many programming resources available. This el uses a c function database for showing arguments. You can either create one yourself or use a ready made one to get you started, a link for which is on the page.
