Hi Jeff!<div><br>Great!</div><div><br></div><div>This is useful in several ways.</div><div><br></div><div>One usecase when it&#39;s quite critical is if implementing networked Gambit-based applications that do not use Gambit&#39;s runtime library.</div>

<div><br></div><div><br></div><div>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&#39;s IO system:</div><div>

<br></div><div>I believe there is some UDP support implemented into Gambit&#39;s ports system, Marc mentioned he has preliminary such in this email <a href="https://mercure.iro.umontreal.ca/pipermail/gambit-list/2006-July/000769.html">https://mercure.iro.umontreal.ca/pipermail/gambit-list/2006-July/000769.html</a> . I&#39;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.</div>

<div><br></div><div>I thought I remembered there&#39;s an IPv6 patch for Gambit&#39;s builtin IO but can&#39;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.</div>

<div><br></div><div>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 library. </div><div><br></div><div>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.</div>

<div><br></div><div>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 connection.</div>

<div><br></div><div>Best regards,</div><div>Mikael</div><div><br><div class="gmail_quote">2012/10/25 Jeff Read <span dir="ltr">&lt;<a href="mailto:bitwize@gmail.com" target="_blank">bitwize@gmail.com</a>&gt;</span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p>All,</p>
<p>The socket library I&#39;ve been working off-and-on on for some time is now listed on the Dumping Ground. Gamsock is a POSIX socket library with an API similar to the Scsh socket API. It makes applications possible with Gambit that aren&#39;t possible with its built in TCP port API, including applications that use UDP, or Unix-domain or IPv6 sockets.</p>



<p>It&#39;s available on GitHub: <a href="https://github.com/bitwize/gamsock" target="_blank">https://github.com/bitwize/gamsock</a></p>
<p>Happy socket hacking!</p><span class="HOEnZb"><font color="#888888">
