Hi Jeff!


This is useful in several ways.

One usecase when it's quite critical is if implementing networked
Gambit-based applications that do not use Gambit's runtime library.

Some side reflections on Gambit UDP/IPv6 support and uses for direct access
to socket routines like your library provides and cooperation between that
and Gambit's IO system:

I believe there is some UDP support implemented into Gambit's ports system,
Marc mentioned he has preliminary such in this email
https://mercure.iro.umontreal.ca/pipermail/gambit-list/2006-July/000769.html .
I'd be interested in getting my hands on this someday as it supposedly is
integrated with the Gambit scheduler, which is useful for several things.

I thought I remembered there's an IPv6 patch for Gambit's builtin IO but
can't find any reference to it right now. In all cases it would be a very
worthy thing to do, to get UDP and hybrid-IPv4-v6 support into Gambit.

There are ways to wrap OS sockets into Gambit ports and the other way
around (for TCP only?). Sometimes this is useful. Could be explored by a

For instance, to make a Unix socket server and client Gambit port
implementation. If of interest to anyone, I have code for one or two
routines in this area to share.

Or, doing accept:s with your library in such a way that the IP of the other
host is registered and retained by the Gambit application, and then
otherwise keeping ordinary Gambit TCP port behavior for the accepted
