creating functions in CodeIgniter controllers

Question

I have a CodeIgniter application, but one of my controllers must call a data processing function that I have also written myself. The only problem is I can't seem to figure out how to do this. Looking through the user guide it seems that I should put my function inside the class declaration, and prefix it with an underscore (_) so that it cannot be called via the url. However, this is not working. Here's an example of what I mean:

<?php
class Listing extends Controller
{
    function index()
    {
        $data = "hello";
        $outputdata['string'] = _dprocess($data);
        $this->load->view('view',$outputdata);
    }
    function _dprocess($d)
    {
        $output = "prefix - ".$d." - suffix";
        return $output
    }
}
?>

The page keeps telling me I have a call to an undefined function _dprocess()

How do I call my own functions?

Thanks!

Edit:
I've gotten it to work by placing the function outside of the class declaration. Is this the correct way of doing it?

ideally, it should be inside the controller

This line is creating problem for you:

$outputdata['string'] = _dprocess($data);

Replace with:

$outputdata['string'] = $this->_dprocess($data);
