IMHO, addrinfo/getaddrinof/freeaddrinfo are much better than those obsoleted gethostbyname.... The reasons are simple. 1. getaddrinfo is thread-safe. And not all OS provide those functions like gethostbyname_r 2. getaddrinfo resovle one name to multiaddresses, especially a name with both IPv4 addresses, and IPv6 addresses. And since all operations on Socket are protocol-independent, I think a combined ip4/ip6 address class is enough. >Boris Schaeling also commented in >news://news.gmane.org/gmane.comp.lib.boost.devel/12305 _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
