c++ - How can i implement simple boost.asio mulsticast sender? -

i want use boost.asio create multicast udp sender. have thread , want use boost for:

• socket;

• send();

• error handling;

can suggest something?

this relatively simple accomplish. here's basic class handles of need using synchronous calls:

#include <boost/asio.hpp> #include <boost/scoped_ptr.hpp>  class multicastsender { public:    multicastsender(const boost::asio::ip::address& multicast_addr,       const unsigned short multicast_port)          : ep_(multicast_addr, multicast_port)    {       socket_.reset(new boost::asio::ip::udp::socket(svc_, ep_.protocol()));    }     ~multicastsender()    {       socket_.reset(null);    }  public:    void send_data(const std::string& msg)    {       socket_->send_to(          boost::asio::buffer(msg.str()), ep_);    }  private:    boost::asio::ip::udp::endpoint                  ep_;    boost::scoped_ptr<boost::asio::ip::udp::socket> socket_;    boost::asio::io_service                         svc_; }; 

this simple class meets 2 of 3 requirements (no error handling). use it, create instance of in appropriate place, , thread implementation calls multicastsender::send_data() send multicast data associated endpoint.
