Peter,

I'm writing an IPv6 application, so which function can get the IPv6 inteface
information? And how to call it?

Thanks,
Zheng

Sorry, I'm not really an IPv6 programmer, hopefully others can help
you.

BTW: if someone has some written information about using the APIs,
would be nice if can be contributed to the HowTo.

Thanks,
        Peter

The best way is probably to look at the 'ip' sources which use netlink to
query the kernel.

You may want to use getifaddrs() in USAGI libinet6.
