Hi I'm a beginner in linux's device driver.
I am getting below errors -

implicit declaration of function ‘ioperm'
implicit declaration of function ‘sleep’

And when I am adding sys/io.h then i am getting "fatal error: sys/io.h: No
such file or directory.

One more question -

How can I convert scan code to character.

Please reply!
