SYNOPSIS

       #include <errno.h>

       #include <libaio.h>

       static inline void io_set_callback(struct iocb *iocb, io_callback_t cb);

       struct iocb {
            void      *data;
            unsigned  key;
            short          aio_lio_opcode;
            short          aio_reqprio;
            int       aio_fildes;
       };

       typedef void (*io_callback_t)(io_context_t ctx, struct iocb *iocb, long res, long res2);
