# setElementValues

## Declaration

```occ
virtual IOReturn setElementValues(int element_index, IOReportElementValues *values, uint64_t record_time);
```

## Parameters

- `element_index`: index of the _element in internal array
- `values`: IORepoterElementValues to replace those at _elements[idx]
- `record_time`: optional mach_absolute_time to be used for metadata

## Return Value

Return Value IOReturn code

## Discussion

Discussion Atomically update a specific member of _elements[]. element_index can be obtained from getFirstElementIndex().  If record_time is not provided, IOReporter::setElementValues() will fetch the current mach_absolute_time.  If the current time is already known, it is more efficient to pass it along. Locking: Caller must ensure that the reporter (data) lock is held.
