Writing Data from Kernel Space to User Space.

Writing Data from Kernel Space to User Space.

Post by Ramesh » Fri, 01 Feb 2002 15:37:16

Hello All.

I am required to write some data from
Kernel Space to User Space, (write
some data from within a NIC Driver to
a user application).

The write would be basically for every 'x' frames
received on the NIC Card. The user application
needs to capture the data and update a few fields in a
structure in the kernel address space, This would be
read by the Driver and processed.

Kindly let me know how to go about achieving this.

Thanks & Regards.



1. Writing data from Kernel to a data file in user space


Could you please help me with this. I wrote a driver to screen IP
packets. Now I need to collect some data and put them in a file so that
I can do the analysis on them later.

I've tried with a simple file writing technique, my driver can't open
it. I'm using Solaris 2.6 but later I'll move my application to Solaris
2.8 for IPv6.

Thanks for noticing my problem.
