writing a module to expose information
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. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com

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. Alex.
