Hi Brandon,<br><br>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).<br>
<br>Reading another post on FFI in this mailing list I found a link to the following page <a href="http://haskell.org/haskellwiki/Modern_array_libraries">http://haskell.org/haskellwiki/Modern_array_libraries</a> with a section on StorableArrayS. I'm now trying to use this example code to get StorableArray to work.<br>
<br>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.<br>

<br>Ideally I would need some sort of Storable array of char. Is Data.Storable.Array the type I'm looking for? Could someone point me to some code using the same kind of structures?<br></blockquote></div><div><br></div>
