Re: How to find out the C type signature corresponding to a Haskell function type in FFI?

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,
HsInt duma_init(HsInt arg);

Or use int on the C side and CInt on the Haskell side.

fromIntegral can be used for converting integers in Haskell.
