by the way your code is wrong there is no FFITypeArray ofType: so it looks I will have to go straight to
FFITypeArray ofType:'char' size:100 of course for my case what you mention as FFITypeArray ofType: #char size: 100) fromHandle: (handle copyFrom: 1 to: 100) is the one that does exactly what I want.
