Thanks!! What about the other direction? (Haskell function with string result) Christian

How can I convert string arguments (null-terminated strings) to Haskell's [Char]? I saw there is some CString module in package lang of GHC, but I didn't found any documentation about it (e.g. packStringIO...?).
For converting a static null-terminated C string to a Haskell String, use CString.unpackCString. If you need to free the memory used by the original C string afterwards, use CString.unpackCStringIO.
Cheers, Simon
