Thanks for all the answers. I'm testing this right now and simples cases work as expected. However from what I've read it seems it'll get ugly once I try to pass a C array to a Haskell function.
Well, maybe arrays in C have been ugly before trying to pass them to Haskell functions ;)
To elaborate a bit about the C program, it's a small game using OpenGL for output and mouse and keyboard for input.
The SDL package (http://hackage.haskell.org/cgi-bin/hackage-scripts/package/SDL) is quite nice for input handling and window making and whatnot. I have heard it is a bitch to get working on Windows, though. The OpenGL package (http://hackage.haskell.org/cgi-bin/hackage-scripts/package/OpenGL) is good, but can be a real pain to get going because the documentation layout is terrible. To toot my own horn, if your graphics are simple enough (specifically, 2D), you can use graphics-drawingcombinators (http://hackage.haskell.org/cgi-bin/hackage-scripts/package/graphics-drawingc...), which has a simple interface, for output. It depends on SDL, so above caveat applies. But once you learn the pattern, I/O is basically a transliteration from C. The reason I struggle with such C-like libraries in Haskell is that I spend all my time trying to clean them up and make them more Haskell-like. I definitely consider FFI more of a pain (when you want to do anything sophisticated) than the OpenGL package, though. Luke
