	I think you meant getifaddrs(3).  getifaddrs(3) is a wrapper
	around socket(2), sysctl(2), ioctl(2), close(2) and now
	open(2) and read(2).  It was designed to hide the OS specific
	details from application developers.

	named uses getifaddrs(3) if it is available and it supports
	IPv6.  Otherwise we do it the hard way.

	getifaddrs(3) won't save you if the IPv6 stack developers
	havn't provided a non file system method to get the interface
	addresses.  AFAIK the only way to get the list of interface
	addresses under Linux is to use the file system either directly
	or via getifaddrs(3).
