I am trying to implement ioctls with a network driver. However I am
confused as to where the driver is. In order to find the file descriptor
of a character devices one simply uses
file =fopen("dev/foo","r");
fd=fileno(file);
and
ioctl(fd,cmd,arg);
but the network interface doesn't appear

how do I find the pointer to the user space. I have tried to use fopen()
etc. but there are conflicts when I try to include "stdio.h". As this is

I'm trying to write between the application level and the kernel. I am
using version 2.0.34 and am attempting to use memcpy_tofs and
memcpy_fromfs, but am having some trouble. If I use these functions in
