Detailed Description

IP address

As a UDP library, libudipe only supports IPv4 and IPv6 addresses, i.e. sockaddr_in and sockaddr_in6 in POSIX parlance. As a special extension, sa_family == 0 is interpreted as requesting some default address.

This union does not need to be accompanied by a tag because the sockaddr types features a sa_family internal tag that enables IPv4/IPv6/default disambiguation.
