setElementValues

Declaration

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

IOReturn code

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.
