Maybe it helps:

 I am building a LKM in which I need to check whether a file is inside
 a particular directory(directly or inside sub-directories). Is there a
 function for this? Do I need to use the lookup function in
 inode_operations for this or is there a better method?

Re: Translate keysyms to ASCII

[Gabriel Duarte]

Anyway, does not work...
I just would like to know if the kernel offers me a conversion table. As I
said, I did it already by myself, but was just looking for a more stylish
way to do...

 Subject: Translate keysyms to ASCII

 Hello people,


 I working on a small proof of concept keylogger that works on kernel mode.
 It's parte of my studies of kernel development.
 I'm using the struct keyboard_notifier_param to get the keys pressed on
 the keyboard(s) attached to the system.

 At the end, I print the value, like this:

 printk(KERN_DEBUG KEY== %i, param-value);


 According to the definition of the struct keyboard_notifier_param at
 http://lxr.free-electrons.com/source/include/linux/keyboard.h#L37, the
 field value is a  keycode, unicode value or keysym.

 For example, when I press the key a, I get the value 30, but I would like
 tranlate it to the ASCII. I managed to create a translation table by
 myself, but I think there is another way more stylish to do this, or not? I
 googled a lot but could not find a consistent answer.

 Any help is appreciated,

 Gabriel.

 The term I think you want to search for is PC keyboard scan code. This
 link seems to cover it pretty well:
