gethostbyaddr() is considered obsolete, I think.
You should use getaddrinfo() instead, which is more
flexible and easier to use, and it enables you to
easily write code that is independent and agnostic
of the address family (IPv4 vs. IPv6 vs. others).
The manual page contains detailed example code.
