Hello all:
I'm curious what or where I might begin writing a module that will allow 
a program to retrieve information from it? Essentially: I need some sort 
of interface through which I can request information and get it returned 
somehow.

Thanks,
Ty

Your module could create a device driver and you could issue ioctl's
to send/retrieve arbitrary information.

You could use proc entries to set/retrieve information.

These are probably the most common methods to do what you want.

Most likely you will want to expose your information through a /proc
or /sys entry. There are plenty of tutorials about how to do this on
the web.
