[asio-users] asio::async_read with a udp::socket?

[<da...@ty...>]

Hi,

This might be a dumb question :)

I'm trying to change the serialization sample code found among the 
examples to work on UDP sockets instead of TCP sockets. As a first shot, 
I simply replaced the tcp::socket types everywhere with udp::socket 
types. And now I get the following compilation error:

connection.hxx:67:   instantiated from ‘void 
s11n_example::connection::async_read(T&, Handler) [with T = 
std::vector<s11n_example::stock, std::allocator<s11n_example::stock> >, 
Handler = boost::_bi::bind_t<void, boost::_mfi::mf1<void, 
s11n_example::client, const asio::error&>, 
boost::_bi::list2<boost::_bi::value<s11n_example::client*>, 
boost::arg<1> > >]’
client.cxx:41:   instantiated from here
/usr/include/asio/impl/read.ipp:174: error: ‘class 
asio::basic_datagram_socket<asio::ip::udp, 
asio::datagram_socket_service<asio::ip::udp> >’ has no member named 
‘async_read_some’
make: *** [client.o] Error 1


The line in question that give the error message:

     asio::async_read(socket_, asio::buffer(inbound_header_),
         boost::bind(f,
           this, asio::placeholders::error, boost::ref(t),
           boost::make_tuple(handler)));



what would be the proper way to call asio::async_read with a UDP socket?

PS: my ultimate goal is to serialize objects using a multicast socket - 
a server casts the serialized data, and multiple clients pick it up.
