[penghoujia]

if (host == "255.255.255.255")
{
option_value = 1;
if (::setsockopt(socket_, SOL_SOCKET, SO_BROADCAST, reinterpret_cast<const char *>(&option_value), sizeof(option_value)) < 0)
{
int last_error = ::WSAGetLastError();
cleanup_();
throw_winsock_error_("error: setsockopt(SO_BROADCAST) Failed!", last_error);
}
}
