Not really; it's not supported. What are you trying achieve in the first place? Loop through all interfaces and addresses and add or delete them to our own list of addresses. I guess that I could also use a kernel socket and an ioctl to get the information, but the code is shared between the FreeBSD kernel, other platforms and Mac OS X. I'm trying to keep the platform specific code minimal... I know that I'm using an unsupported API. It is part of a NKE which implements a transport protocol (SCTP). This is not possible using only supported APIs, but it currently works (and might break in the future, I know). This email sent to adi@apple.com This email sent to site_archiver@lists.apple.com
