We had to write portable local address detection for Web Polygraph. In my experience, ioctl/SIOCGIFADDR is not portable at all and is a lot of pain. Linux uses them differently from FreeBSD, and the exact interface/behavior is often OS-version specific (e.g., for Solaris IIRC). Looking at existing code helps. I would suggest using getifaddrs(3) where available (./configure can detect that, of course) and delve into ioctl() and other OS-specific methods where getifaddrs(3) is not supported. Stockpile some pain relieve medication first. $0.02, Alex. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
