id3lib did something like that and it was a source of all kinds of problems 
(many of which I fixed back when I was working on it).  TagLib provides 
functions in the TagLib::File API to do insertion and replacement directly 
into files that will handle moving back the contents of the file.

If those functions don't provide what you need if you could describe what it 
is that you need in more detail I could probably write functions to handle 
your requirements without a temp file.
