Change the Module Page link

Hi! I have a question I’ve been working on for a while. I’ve written my own module and want to change its module control panel link to pass in an argument so that I don’t get php warnings when I load the module. The reason that I want to pass in arguments is so that in the module can call my index function with success or failure messages. I could create an identical function with a different name (function overloading is not good in php), but I really don’t want to have to maintain both functions. I would rather make the control panel submit an empty string as an argument so that I don’t get the warnings. Does anyone know how to change the control panel link for a module?

Thanks in advance!
