Subject: [PATCH] socket: Add IPPROTO_IPV6 and IPV6_V6ONLY.
Date: Fri, 13 May 2022 12:51:14 +0100 [thread overview]
Message-ID: <20220513115114.7821-1-mail@cbaines.net> (raw)
Add constants to enable setting sockets to be IPv6 only. This is useful
if you want to listen on a port via IPv4 and IPv6 as the socket for IPv6
may need setting to be IPv6 only to avoid conflicting with the IPv4
socket.
* libguile/socket.c (IPPROTO_IPV6, IPV6_V6ONLY): New constants.
