DESCRIPTION
When processing event records, if pmUnpackHighResEventRecords(3) is used to unpack event records from a metric within a pmResult structure with a value of type PM_TYPE_HIGHRES_EVENT then the structure returned from pmUnpackHighResEventRecords(3) is a NULL pointer terminated array of pointers to pmResult structures, one for each event record.

pmFreeHighResEventResult is a convenience method that frees all of the pmResult structures and the array of pointers (hrset).

Similarly, pmFreeEventResult may be used to free the pmResult_v2 structures and array returned from the pmUnpackEventRecords routine when using PM_TYPE_EVENT metrics.
