hi I have recently started to create a realtime ARCnet protocol and implement it as a linux kernel module. Sofar it works fine, can be loadet and my testapp (another module) works fine to. Now I want to make the functionality available to a program in userspace. I have functions like bind,connect, recieve and send (ofcause with non-conflicting names) and these are in a module of it's own. I thought that I by including the headerfile for the module in my userspace app, then I could access them that way (the functions are declared as extern). However I found out that this is not the case. So what should I do now? how do I access my module from userspace?
