The behavior matches getaddrinfo():
If the AI_PASSIVE flag is specified in hints.ai_flags, and node is
NULL, then the returned socket addresses will be suitable for
bind(2)ing a socket that will accept(2) connections. The returned
socket address will contain the "wildcard address" (INADDR_ANY for
IPv4 addresses, IN6ADDR_ANY_INIT for IPv6 address). The wildcard
address is used by applications (typically servers) that intend to
accept connections on any of the host's network addresses. If node
is not NULL, then the AI_PASSIVE flag is ignored.
You can call getaddrinfo() without the passive flag and simply use the returned address as input into bind, provided that you know the address is local.
