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.

Hi,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.

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