The errno package
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.
