hi!
   I am beginning learn to write a driver follow the
Book "Beginnng Linux programming(Second
Edition)".There is a example about char driver,I write
as that,but I can open device,but can't read from it.I
just copy some static data to user buffer as follow:
   copy_to_user(buf, schar_buffer, count)

Thanks,
xin
