You ought to use a C wrapper around these sorts of things. If you're lucky, the API docs will tell you which values and functions might be macros, e.g. http://www.opengroup.org/onlinepubs/007908799/xcurses/curses.h.html is clear about what is (or might be) what. I can't remember if it's been discussed before, but I think it might be a good idea for the FFI to be able to create these C stubs itself, if you give a certain keyword - or perhaps even by default as it's the safe thing to do, at the expense of performance. Thanks Ian
