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.
