Ok, I've just uploaded an improved version, which can also handle
binary data in "getvalue" (untested!).  If you want to convert the
binary data directly in C, i.e. without going through OCaml-strings,
you will have to extend the C-interface.  I'm too busy right now to do
it myself, but I'll gladly accept patches :-)

If you send a patch, please make sure that error handling is
implemented, too. - Thanks!

Regards,
Markus
