Oh, do you mean by actually calling memcpy via ffi?

Ah, thanks. Is there a way to simply "cast" an IOUArray Int Int64 into something like a Ptr Int64, or will I need to change my code to allocate the arrays differently (using something in Foreign.*)? I hoogle'd functions "IOUArray a b -> Ptr b", but couldn't find anything. Denis
