PMFREERESULT(3)         Library Functions Manual         PMFREERESULT(3)

ИМЯ

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

C СИНТАКСИС

       #include <pcp/pmapi.h>

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

ОПИСАНИЕ

       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 pmResult structure.

       Under no circumstances should an application use free(result) to
       release storage previously allocated for a pmResult 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.
