Hello Brian,

Also, I really wanted to be able to use () -> IO () but () doesn't seem to be allowed in FFI...

void f(void);

foreign import ccall f :: IO ()

Thanks Bulat for these function prototypes (+ the links you posted). I'd thought that it would be complicated to deal with the IO monad but I see from these prototypes that it's not so complicated after all... :-) Best regards, Brian.
