pmFreeResult - release storage allocated for performance metrics values
#include <pcp/pmapi.h> void pmFreeResult(pmResult *result); cc ... -lpcp
The variable sized results returned by pmFetch(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 pmResult structure. Under no circumstances should an application use free(result) to release storage previously allocated for a pmResult by pmFetch(3).
