For debugging or writting some simple apps you could also use
iproute2/genl
example on my laptop to discover loaded users:

===============
You essentially write a little .so in user space that knows how to
access/intepret your kernel module
I know you are avoiding to use external libraries etc; but this may be a
good way to get started.
I can dig up some simple kernel/user code i have and if you bug Thomas
long enough he may give you another sample code he has.
cheers,
jamal
