There is also c2hs which is well supported and is used for several large C bindings: http://www.cse.unsw.edu.au/~chak/haskell/c2hs/ It works at a higher level than hsc2hs and can make writing bindings quite a bit simpler and cleaner. For example the cairo bindings use it: http://darcs.haskell.org/gtk2hs/cairo/Graphics/Rendering/Cairo/ see the various .chs files, for example: http://darcs.haskell.org/gtk2hs/cairo/Graphics/Rendering/Cairo/Internal/Drawing/Paths.chs Duncan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
