I have a question regarding the function:
static int tty_write(struct inode *inode, struct file *file, char *buf, int count);
in the file "drivers/char/tty_io.c".
Is there a way to determine, from within tty_write(), if the char(s) in "buf" have resulted from a keyboard interrupt? To put it another way, how do I detect keyboard chars from other kernel/appl. output?
What are you trying to do, and why do you care? It sounds like you want to seriously violate an abstraction barrier, and there's probably a better way of doing things.
