How do I override the not found page in CodeIgniter?

Question

I have a CodeIgniter application that\'s generally working how I\'d like it to, but occasionally a user will go to a page that does not exist and is greeted with an unfriendly e

You should test for error return values and catch exceptions. This is a general programming concept - not something specific to Conigniter or PHP.

Testing for error return values:

if (!sort($array))
{
    echo "Could not sort $array.";
}

Catching exceptions:

try
{
    $someFunction($data);
}
catch (Exception $e)
{
    echo "Something went wrong";
}

Of course write useful error messages with pertinent info that helps the user find their problem, and/or helps you fix your bug. You could get advanced and use something like set_error_handler(): http://php.net/manual/en/function.set-error-handler.php

I found this interesting article: http://www.derekallard.com/blog/post/error-handling-in-codeigniter/

I'm not sure it reflects the current CI release as it's from 2007.
