Hey Daniel, Thanks for the quick reply.
The IBM tutorial helps me writing the function for handling user reads and writes to your corresponding proc file. It doesn't help in terms of opening and writing from the kernel side. the example you provided just creates a proc entry. It doesn't tell me how to write to it. Please help. Thanks, Suren Nihalani. ----- Original Message ----- From: "Daniel Baluta" <[email protected]> To: "Surenkumar Nihalani" <[email protected]> Cc: [email protected] Sent: Sunday, February 5, 2012 4:20:28 PM Subject: Re: How to use /proc On Sun, Feb 5, 2012 at 11:07 PM, Surenkumar Nihalani <[email protected]> wrote: > Hello Guys, > > I am CS student trying to write a kernel module as a part of my class > assignment.

Another approach is to see how an existing proc entry is handled. Look for example at /proc/sched_debug [2]. thanks, Daniel.
