NAME         top

       pmFreeEventResult, pmFreeHighResEventResult - release storage
       allocated for unpacked event records

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       void pmFreeEventResult(pmResult **rset);
       void pmFreeHighResEventResult(pmHighResResult **hrset);

       cc ... -lpcp

DESCRIPTION         top

       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 (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.
