This is unfortunately not documented. Patches welcome.

The avahi-python bindings contain a listing of all necessary codes.

Also, the C API is mostly a 1:1 wrapper of the D-Bus API, so it should
be fairly easy to extract to appropriate enums from
avahi-common/defs.h and avahi-common/address.h.

The interface parameter just takes a system interface number. As
returned by if_nametoindex(). Use -1 if you want to register a service
on all interfaces at the same time (which is what most apps probably
want to do). protocol and aprptocol use the enum defined on top of
address.h. (i.e. 0 for INET4, 1 for INET6, -1 for both)

Hope this helps,

Lennart
