I am currently involved in a project whereby I will receive, from a FIX engine, a FIX message body. I have to decode the message body and possibly encode a reply the FIX engine can insert into a FIX message.  
My question - does anyone know of the existence of any general purpose libraries that will aid the task of constructing and de-constructing FIX buffers.
