title: Checking simple char device read/write functions in LINUX
body: <p>I am new to linux kernel programming. I wrote a simple kernel module and char device. I  defined the open(), release(), read() and write() methods of device. I initialize my module with insmod and removed it with rmmod and all works correct. Now I want to check my read() write() methods of the device. Could you please tell me how to write a user program which should implement the read/write methods of my char device ? Thank you.</p>
