[Boost-users] [Asio] Making custom std::streambuf for async_read

At the moment I'm using async_read with boost::asio::streambuf and this works fine but I need a custom stream where every invoke to async_read appends the data to my stream. The stream should be based on std::streambuf because I want to keep the asio interface hidden to the user. My first idea was to search for the problem and I ended up with reading about MutableBufferSequence but I don't know if this is the right way and how to implement this in my streambuf object. Any help is higly appreciated.
