Re: Approach to sin_zero

Here's a version that uses getaddrinfo:

sock_type cmw::udp_server (uint16_t port)
{
   ::std::ostringstream out;
   out<< port;

   addrinfo* res;
   addrinfo hints;
   ::std::memset(&hints, 0, sizeof(hints));

   hints.ai_family = AF_UNSPEC;
   hints.ai_socktype = SOCK_DGRAM;
   hints.ai_flags = AI_PASSIVE;

   int err;
   if ((err = ::getaddrinfo(nullptr
                            , out.str().c_str()
                            ,&hints
                            ,&res
                           )) != 0) {
     throw failure("udp_server getaddrinfo: ")<< gai_strerror(err);
   }

   sock_type sd = getSocket(SOCK_DGRAM);
   if (::bind(sd, res->ai_addr, res->ai_addrlen)==-1) {
     throw failure("udp_server bind: ")<< GetError();
   }
   return sd;
}

The unfortunate thing is the change adds over 2,000 bytes
to an executable. It isn't a big executable and the
percentage increase is close to 3%. That strikes me as
excessive. Are there any other alternatives?
