Mornin,
i have since solved the problem of passing info
to and from the kernel - I'm using my own ioctls - which
solves the problem perfeclty. The next problem I hit is
this:
I have 2 devices being monitored by the same
kernel module. When one device is accessed and info is
passed in, the module notifies a user process which then
gets the info thru the other deivce, acts on it, and passes
back the result. My problem is I need the module to block
(or something) until the info has being passed back before
returning from the ioctl call made on the first device.
Any ideas?
I prolly haven't made a very good description so feel free
to ask any q's.
Need help, cause if I can't solve this, my Final Year
Project is stillborn.
Steve
