Hi -
I've got a Haskell module with the following ffi import:
foreign import ccall duma_init :: Int - IO Int
However my problem is that I've got no idea what the type signature for the
corresponding C function should be, and when I compile the above module with
ghc -fglasgow-exts -fffi --make

BH examples. I'm trying to find what the mapping is between Haskell function

I've set up my Visual Studio environment so that ghc is an external tool,

In unix you could wrap ghc in a script that would print Done if ghc
finished successfully. I am sure you can do it somehow in windows.

What for? IO is the monad that most closely matches the imperative, C
semantics. That's why FFI only supports the IO monad (and pure
functions). Other

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

Hello,
there was some proposal for introducing a special syntax where f x _ z or
f x ? z means \y - f x y z. Is there some information on the Haskell' trac
site about this?

happy with that, as you can probably imagine.
I would also imagine that Joe Programmer is more likely to use
wxHaskell or Gtk2Hs than those - however because those are outside the
standard tree they don't make it in. I don't think much
