Hi,
  As mentioned earlier, I can control snp(4) with my own code with ioctl. 
That is, I can modify or override the original snoop in FreeBSD. However, 
even I read through the man pages, I still don't know how to start. For 
example, where should I place my own .c or .h files? What header files (.h 
files) should I or can I include in my own programs?
I would appreciate if someone can guide me about this.
  Thanks!

Regards,
Wing
