Reading between the lines and guessing - here's what you can do:
Write a userland program that (1) reads /dev/fooctl, (2) does something based on what it got from /dev/fooctl, and (3) goes back to step (1).
Then write a kernel driver that produces output on /dev/fooctl every time it wants the userland program to do something.
This achieves the effect you (probably) want while maintaining the seperation between kernel and userland. HTH, -Chris
That's the point. I do not want the userland program to check /dev/fooctl from time to time. I want the kernel to notify the userland program instead. So how shall I do it? Maybe linker_load_file is a better way.
Thx. Gordon
