NAME

       pmFreeLabelSets - release storage allocated for performance metric labels

C SYNOPSIS

       #include <pcp/pmapi.h>

       void pmFreeLabelSets(pmLabelSet *sets, int nsets);

       cc ... -lpcp

DESCRIPTION

       The  array  of  label  sets  returned  by  pmLookupLabels(3)  and  related  APIs  are allocated below the
       Performance Metrics Application Programming Interface (PMAPI) using a variety of calls  to  the  system's
       dynamic memory allocation (i.e. malloc(3)) interfaces.

       Applications  should  call pmFreeLabelSets to release the storage previously allocated for the label sets
       array when access to the structure is no longer needed.  The return value from  pmLookupLabels  indicates
       the number of elements in the label sets array, and this should be passed in using the nsets parameter.

       Under  no  circumstances should an application use free(labelset) to release storage previously allocated
       for a pmLabelSet by pmLookupLabels(3) or related APIs.
