aclrtQueryEventStatus
Description
Queries the execution status of all tasks captured in an event. For more details, see aclrtRecordEvent.
Restrictions
If aclrtRecordEvent and aclrtQueryEventStatus 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.
