io_queue_run - Handle completed io requests
int io_queue_run(io_context_t ctx);
io_queue_run() attempts to read all the events from the completion queue for the aio_context specified by ctx.
May return 0 if no events are available. Will fail with -ENOSYS if not implemented.
|EFAULT||iocbs referenced data outside of the program’s accessible address space.|
|EINVAL||ctx refers to an uninitialized aio context, the iocb pointed to by iocbs contains an improperly initialized iocb.|
