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?
