Function: query_event_status

C Prototype	aclError aclrtQueryEventStatus(aclrtEvent *event, aclrtEventRecordedStatus status)**
Python Function	status, ret = acl.rt.query_event_status(event)
Function Usage	Queries the execution status of all tasks captured in an event. For more details, see acl.rt.record_event.
Input Description	event: int, pointer address of the event object to be queried.
Return Value	status: int, pointer address of the event status. ACL_EVENT_RECORDED_STATUS_NOT_READY = 0: The event is not recorded in the stream, or the event recorded in the stream is not executed or fails to be executed. ACL_EVENT_RECORDED_STATUS_COMPLETE = 1: The event recorded in the stream is successfully executed. ret: int, error code. 0 indicates success. Other values indicate failure.
Restrictions	If acl.rt.record_event and acl.rt.query_event_status are called on different threads, the execution time of the two APIs may be out of order. As a result, the completion status of the queried event object does not meet the expectation.
