The functions gethostbyname() and gethostbyaddr() are used to resolve host names and addresses in the domain name system or the local host's other resolver mechanisms (e.g., /etc/hosts lookup). They return a pointer to an object of type struct hostent , which describes an Internet Protocol host.
Then, if hostname is given (not NULL), a call to gethostbyname() resolves it, or otherwise the address 0.0.0.0 is used, if hints->ai_flags is set to AI_PASSIVE, and 127.0.0.1 otherwise. It allocated a new addrinfo structure filled with the appropriate sockaddr_in in one of these conditions and also adds the port retrieved at the beginning to it
