[Boost-users] [asio] Using tcp::iostreams with Boost.Iostreams filtered_streambuf

Hi, I was wondering about tcp::iostreams. I need to have the ability to write code like: obj<< "Hello world" and at intervals (of size) have a header attached and then have it written to an open socket. I have been looking into Boost.Iostreams to do this, but I was wondering if rather than implementing the whole streambuf/sink, I could just create a filtering_streambuf (naming convention taken from Boost.Iostreams) - which would attach the header when needed - and just instantiate a tcp::iostream object with that streambuf. I'm still very foggy on the Iostreams library - and streams/buffers in general - but does that sound like it could work? Sorry about the vagueness, Darren
