did you actually read the question (the 1st post in the forum under
this topic)? I have written the code explicitly there:

if(!m_udpSocket.is_open())
   {
      m_udpSocket.open(m_localEndpoint.protocol(), errorCode);
//m_localEndpoint is address 0.0.0.0 and port X
      if(errorCode)
      {
         std::cerr << "Unable to open socket: " << errorCode.message()
<< std::endl;
      }
      else
      {
         m_udpSocket.set_option(boost::asio::socket_base::reuse_address(true),
errorCode);
         if(errorCode)
         {
            std::cerr << "Reuse address option set failure. " <<
errorCode.message() << std::endl;
         }

         m_udpSocket.set_option(boost::asio::socket_base::broadcast(true),
errorCode);
         if(errorCode)
         {
            std::cerr << "Socket cannot send broadcast. " <<
errorCode.message() << std::endl;
         }
         else
         {
            m_udpSocket.bind(m_localEndpoint, errorCode);
            if(errorCode)
            {
               std::cerr << "Socket cannot bind...!! " <<
errorCode.message() << std::endl;
            }
         }
      }
   }

Do you mean there's anything wrong with this?
