It's for porting RSPFd over to NOS, so its packets sit on top of IP.
So what I do in Linux is open a SOCK_RAW socket with the RSPF PID, tell the
socket I'd like to be able to send broadcast packets
setsockopt(SO_BROADCAST), then do a sendto(). For Rx, I use a socket of
type packet, which recieves everything. In NOS, I think a RAW socket
filtered by the PID may do.

Right, this is what I meant. The "nicer" way would be some sort of
function. But as NOS is one program, you can look at almost everything.

I need these to hold lists of adjacencies or routers, link-state databases
etc, so I'll just port these across from the daemon. I thought there might
of been a "generic linked-list manager" in NOS, as it could use so many for
ARP caches, routing tables etc.
The main point to my message was I was hoping would say "don't do it like
spaghetti.c, it looks directly at structures and just doesn't behave, try to
do things like they have done in nice.c". An example is buf[x] or using
pullchar().

It will be a great idea, at present I have a Apple NEWTON 130 (PDA), and I
wonder if it could be possible to use it with TCP/IP over radio ...

I may be going out on a limb here, but I've been reading and playing
with Java for about a week now. I realize it's just a p-code virtual
machine, but it does incorporate networking and serial code. I don't
believe it has serial port code out of the box. Could I be wrong in
saying "It's good enough."
This seems to be an excellent way to migrate away from the very low
level code of NOS.
