| 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. |
