boost::asio 使用实例

 #include <iostream>
 #include <boost/asio.hpp>

 using namespace std;
 using namespace boost::asio;

 int main()
 {
     try
     {
         cout << "server start." << endl;
         io_service ios;

         ip::tcp::acceptor acc(ios,
             ip::tcp::endpoint(ip::tcp::v4(),));

         cout << acc.local_endpoint().address() << endl;

         while (true)
         {
             ip::tcp::socket sock(ios);
             acc.accept(sock);

             cout << "client:" ;
             cout << sock.remote_endpoint().address() << endl;

             sock.write_some(buffer("hello asio"));
         }
     }
     catch (std::exception& e)
     {
         cout << e.what() << endl;
     }

     return ;
 }

tcp client:

 #include <boost/asio.hpp>
 #include <iostream>

 using namespace std;
 using namespace boost::asio;

 void client(io_service &ios)
 {
     try
     {
         cout << "client start." << endl;

         ip::tcp::socket sock(ios);
         ip::tcp::endpoint ep(ip::address::from_string("127.0.0.1"),);

         sock.connect(ep);

         vector<char> str(,);
         sock.read_some(buffer(str));
         cout << "receive from " << sock.remote_endpoint().address();
         cout << &str[] << endl;
     }
     catch (std::exception& e)
     {
         cout << e.what() << endl;
     }
 }

 void print(const boost::system::error_code&)
 {
     cout << "test wait..." << endl;
 }

 int main()
 {
     io_service ios;
     deadline_timer at(ios, boost::posix_time::seconds());
     at.async_wait(print);

     cout << "it show before at exired" <<endl;
     ios.run();
     return ;
 }
