Some more detail on the AdaCore binding translator Jacob mentioned ...
Recently I decided I wanted a binding to C package, googled for
a tutorial, and found gem 59 and gem 60

http://www.adacore.com/2009/02/23/gem-59/

Thanks AdaCore!  I couldn't have written a binding myself even
in the easiest limit. All I did was type (iirc)
       g++ -c -fdump-ada-spec -C  file_name.h
and it wrote the thing for me.  Lot's of tedious complications
due to C strings and the like were taken care of.  A few things it
did wrong, but not too bad .. even I could fix it.
