As I understand it, you can't do this;you must use the same aiocb throughout (that is, the same chunk of memory, not merely the same values; there is quite possibly a kernel mapping to it which you can't change or copy, or a pointer to the original aiocb is kept as internal state in the aio library so it can update the errno and result on the fly).
