The other question would be: why doesn't it work.  I recently converted
some of my older streambuf's to the new iostream (as implemented in VC++
5.0), and was pleasantly surprised how few changes were involved.

My book, The Draft Standard C++ Library, discusses the new
iostreams protocol in enough detail that you should be able to
derive from these classes. The book predates templatization of
the library, but it is still highly relevant in the area you seem to
be most concerned about.

Can anyone recommend a good source for documentation about extending the
(std, templatized) iostream library?  I'll happily go out and by a book on
the subject but I simply can't find one that covers what I want.

Specifically I want to do somethig like this.  I want to use an ostream to
output formatted text (either to a window or a file), the formatting will be
probably be rtf but may need extending to support html.  To do this I wanted
to provide an ostream derivative that supports various formatting
manipulators but that's where the problems start.

Anyway I won't go into details since I don't have them here but basically
what I thought would be simple, and in fact was simple when I did something
similar with the old iostream library just doesn't work any longer.  Clearly
I need a refresher, the question is from where?
