Summary	0001289: netdb.h - in_port_t and in_addr_t do not appear to be needed
Description	Ref: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/netdb.h.html In netdb.h, both in_port_t and in_addr_t are “may define” but do not appear to be needed. In discussing this, our assumption is that when this header was added to the standard, at least one implementation defined or needed these two types. They do not appear to be strictly needed.
Desired Action	Clarification/update is requested.

shware_systems 2019-09-27 19:58 reporter bugnote:0004572	While not directly referenced, the addrinfo structure and getnameinfo() interface use the incomplete sockaddr type, which in practice will be completed with members of those types for IP4 and IP6 sockets. The current wording is, I strongly suspect, from known implementations all doing a #include of another header that declared these types and completed sockaddr before any of the new declarations and prototypes, to leave open some implementaton may choose not to do it this way. The types are required, however, as sockaddr is required to support IP4, at least.
