PMFREERESULT(3)

NAME
pmFreeResult, pmFreeHighResResult, - release storage allocated for performance metrics values

C SYNOPSIS
#include <pcp/pmapi.h>

void pmFreeResult(pmResult *result);
void pmFreeHighResResult(pmHighResResult *result);

cc ... -lpcp

DESCRIPTION
The variable sized results returned by pmFetch(3) and pmFetchHighRes(3) are allocated below the Performance Metrics Application Programming Interface (PMAPI) using a combination of dynamic (i.e. malloc(3)) and specialized allocation strategies.

Applications should call pmFreeResult to release the storage previously allocated for result by pmFetch(3), when the application no longer requires access to the structure.

Under no circumstances should an application use to release storage previously allocated for a by pmFetch(3).

Similarly, memory allocated for the high resolution timestamped result structure returned from pmFetchHighRes(3) should be released by a call to pmFreeHighResResult.
