Hi Brandon, Thanks for your help, CString will work great for Char arrays, but what about the 16bit-Word arrays? I was not clear in my previous post but the structures used in the nwrfcsdk library can use 8bit or 16 bit "chars" depending on a #define (#define SAPwithUNICODE).
Reading another post on FFI in this mailing list I found a link to the following page http://haskell.org/haskellwiki/Modern_array_libraries with a section on StorableArrayS. I'm now trying to use this example code to get StorableArray to work. I will try to use Data.Encoding to convert Haskell StringS to ASCII or UTF16 ByteStringS. Then unpack those ByteStringS to Word8 list and populate StorableArrayS with the bytes. I hope it'll do the job for both Word8 and Word16 arrays. Olivier. On Fri, May 9, 2008 at 9:52 AM, Brandon S.
