Thank Matthias!!!<br>I have tried using printk . What I really want to do now is to implement the methods I have written by calling from the user space. Like I want to read or write to the character devices via user space. <br>

Hi,<br>
I'm new to linux and kernel . I'm ongoing with the linux device drivers.<br>
I've followed the the book LDD but i'm lost about how to call my<br>
driver's specific method from the user space.<br>
Eg: if have developed a character device and inserted the module then<br>
how can i make sure that when I read or write that it implement the<br>
functions via the methods i have implemented in my module.<br>

the most easy way would be to put some printk output in your read/write functions of your driver. So with cat/echo from userspace you should be able to verify your implementation.<br>
