You can also use the newer getaddrinfo(3)/freeaddrinfo(3). I think it is bit easier to use and can it transparently handle inet6 addresses as well. The only downside is that some rare old systems don't support it. On FreeBSD it is suppoorted since FreeBSD-4, but some commerical OS implemented it later. -- B.Walter <[EMAIL PROTECTED]> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
