Thanks Dave for your answer. I guess the same question has been answered several times before. For the interest reader, I've found these:
http://unix.stackexchange.com/questions/4711/what-is-the-difference-between-...
http://lwn.net/Articles/119652/
http://www.mail-archive.com/kernelnewbies@nl.linux.org/msg00269.html
I have a remaining question, though. In the lwn article I read this:
"The ioctl() system call has long been out of favor among the kernel developers, who see it as a completely uncontrolled entry point into the kernel".
Is this pointing that ioctl() is planning to get removed from the kernel ? In that case what's the currently preferred mechanism for giving 'control commands' to device drivers ?
I would bet for 'sysfs'. thanks, Daniel.
