-- | a FFI utility
--   
--   errno is a small utility to supplement the FFI. Many C functions will
--   return a special Int if an error has occurred, and the withErrno*
--   functions allow you to lift them into the ErrorT String transformer. I
--   found this in some cases useful for when I wanted to handle errors
--   from both C & Haskell on equal footing.
