[sr-dev] gethostbyname() usage in resolving hostname

Hello, I have seen that sip-router (and also kamailio) uses the old gethostbyname()/gethostbyname2() (for IPv6) method of resolving hostnames. These calls have been deprecated according to the POSIX 2001 standard these calls are obsolete: Quote from the gethostbyname manpage "POSIX.1-2001 marks *gethostbyaddr*() and *gethostbyname*() obsolescent. See *getaddrinfo <http://linux.die.net/man/3/getaddrinfo>*(3), *getnameinfo <http://linux.die.net/man/3/getnameinfo>*(3), *gai_strerror <http://linux.die.net/man/3/gai_strerror>*(3). " (http://linux.die.net/man/3/gethostbyname) How about changing these calls to the new and improved API(getaddrinfo)? Some benefits of using the getaddrinfo API: 1. Thread safe calls (also async-sig-safe) 2. IPv4/IPv6 compliant 3. Order or returned addresses conforming to RFC 3484 (private network address returned first) (http://udrepper.livejournal.com/16116.html) For a more complete description of the differences , I point to Urlich Drepper's excelent article: http://people.redhat.com/drepper/userapi-ipv6.html Any benefits from using these calls? Any problems from removing the old calls? Cheers, Marius
