Can someone tell me if there is a way to create a type of Keyboard Hook so that any input typed on the keyboard will go through my program first?

I know I can do it by rewiring the keyboard driver, but I'm hoping for a way to do it without messing with any kernel drivers.

Thanks

You mean a keylogger, right?

http://sourceforge.net/projects/lkl/

Why would you wanna do such a thing?

I've been wanting to do the exact same thing although I've been trying to allow for a user to enter in keyboard input, which is routed to two programs.
Some interesting advice i've recieved is to write a wrapper program that runs the two programs in question as a process(or aparantly pthreads) and pipes the keyboard input to both. You might want to look up processes and pipes, let me know if you're sucessfull or find something new because im still stuck on implementation.

Maybe you can get some ideas by looking at the source code for lkl (Linux Keylogger) and then improving it. It needs lots of improvements. I hope you make your keylogger available for Ubuntu in the universe or multiverse repositories. Also your program will be much better than lkl if it has a better output than lkl with time and date and html format. It would be MUCH better if lkl simply sniffed the raw
port data (or read it and echoed it to the kernel) and
logged that, and then came with a viewer to decode the
raw logs. This way there is NO translation done by lkl
to the actual datastream, eliminating any chance of
failure.
