Firstly, some ncurses calls return a *WINDOW and others take one as an argument but you never actually look at the contents of one yourself. I have defined "data Window = Window" and am using Ptr Window for the types of these. However, this means I get a warning about an unused constructor. Is there a better way to do this?
Hugs supports:
data Window
and I believe GHC and NHC do too. (Malcolm, SimonM: please shout if I overstate.)
I'd rather stick to H'98+FFI where possible.
Secondly, does anyone have any suggestions on how to provide an interface to this?
void getyx(WINDOW *win, int y, int x);
The getyx macro places the current cursor position of the given window in the two integer variables y and x.
The type would probably ideally be "Ptr Window -> IO (CInt, CInt)".
[snip] Thanks to you both for your input - I think I'll go with Sven's two element array. Ian
