[Boost-users] xml_oarchive to a iostream

Hi, Am I missing something or is there no way to serialise to a network stream? Using the blocking method for sending and receiving I have a boost::asio::ip::tcp::iostream and need a boost::archive::xml_oarchive to serialise to/from unfortunately I can't work out how to create a xml_oarchive from the network iostream. I see from the examples most people are serialising to a buffer and then sending that but it would be much neater to be able to use a stream directly. Am I missing something or is this a gap? Thanks, M
