This is automatically built in. The Router will do a check to see if there is a folder with the name of segment 1 and a file with the name of the second segment.
In your example you would have this directory structure:
Code:
* application
* controllers
* folder
* Function.php
The only caveat is your naming. This is not a function, its a class. Every controller has to be a class which contains methods (functions).
Check out line 189 of Router.php in the system/libraries folder. This will show you how CI loads cotrollers. If you want to change how this happens you can copy this file into your application/libaries folder and rename to MY_Router.php
Hope this info helps.
