Getting All Controller Functions

[eluser]cpscdave[/eluser]
Hi everyone,
I'm working on implementing some Role Based Security for a site, and one of the things I would like to do is have the code figure out all of the methods that role access needs to be set for.

How can I go about doing this?

I originally tried to instantiate a instance of the controller(s) but when I do I get an error as CI is assuming I'm trying to load a library.

Any suggestions??
