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.
