-   DESCRIPTION
-   io_getevents  attempts  to  read  at  least min_nr events and up to nr
-   events from the completion queue  of  the  AIO  context  specified  by
-   ctx_id.   timeout  specifies  the  amount  of time to wait for events,
-   where a NULL timeout waits until at  least  min_nr  events  have  been
-   seen.   Note  that timeout is relative and will be updated if not NULL
-   and the operation blocks.
-
-   RETURN VALUE
-   io_getevents returns the number of events read: 0  if  no  events  are
-   available or < min_nr if the timeout has elapsed.
-
-   ERRORS
-   EINVAL ctx_id  is  invalid.  min_nr  is  out  of range or nr is out of
-   range.
