socket_udp_ip_v4.cpp

Shows how to use xtd::net::sockets::socket class.

#include <xtd/xtd>

        console::write_line(ustring(buffer.begin(), buffer.begin() + number_of_byte_received));
    }
  });
  
  thread client([&] {

      client_socket.send_to(vector<unsigned char>(str.begin(), str.end()), ip_end_point(ip_address::loopback, 9400));
      this_thread::sleep_for(50ms);
    }
    
    client_socket.send_to(vector<unsigned char> {0xFF}, ip_end_point(ip_address::loopback, 9400));
  });

  server.join();
  client.join();
}

// This code produces the following output:
//
// counter=1
// counter=2
// counter=3
// counter=4
// counter=5
// ...
