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
