Release storage allocated for unpacked event records
#include <pcp/pmapi.h>

When processing event records, if pmUnpackEventRecords(3) is used to unpack event records from a metric within a pmResult structure with a value of type PM_TYPE_EVENT then the structure returned from pmUnpackEventRecords(3) is a NULL pointer terminated array of pointers to pmResult structures, one for each event record.
pmFreeEventResult is a convenience method that frees all of the pmResult structures and the array of pointers ( .IR rset ).
Similarly, pmFreeHighResEventResult may be used to free the pmHighResResult structures and array returned from the pmUnpackHighResEventRecords routine when using PM_TYPE_HIGHRES_EVENT metrics.
