PMFREEEVENTRESULT(3) Library Functions Manual PMFREEEVENTRESULT(3)NAME
pmFreeEventResult - release storage allocated for unpacked event records
C SYNOPSIS
#include <pcp/pmapi.h>
void pmFreeEventResult(pmResult **rset);
cc ... -lpcp
DESCRIPTION
When processing event records, if pmUnpackEventRecords(3) is used to unpack event records from a metric within a pmResult structure with a
value of type PM_TYPE_EVENT then the structure returned from pmUnpackEventRecords(3) is a NULL pointer terminated array of pointers to
pmResult structures, one for each event record.
pmFreeEventResult is a convenience method that frees all of the pmResult structures and the array of pointers (rset).
SEE ALSO PMAPI(3) and pmUnpackEventRecords(3).

pmFetchArchive - get performance metrics directly from an archive log
C SYNOPSIS
#include <pcp/pmapi.h>
int pmFetchArchive(pmResult **result);
cc ... -lpcp
DESCRIPTION
pmFetchArchive is a variant of pmFetch(3) that may only be used when the current Performance Metrics Application Programming Interface
(PMAPI) context is associated with an archive log.
The result is instantiated with all of the metrics (and instances) from the next archive record, consequently there is no notion of a list
of desired metrics, and the instance profile of the PMAPI context is ignored.
It is expected that pmFetchArchive would be used to create utilities that scan archive logs, while the more common access to the archives
would be via the pmFetch(3) interface.
To skip records within the archive log, use pmSetMode(3) to change the collection time within the current PMAPI context, then call
pmFetchArchive.
Note that the result returned by pmFetchArchive is dynamically allocated, and must be released using pmFreeResult(3), not free(3C). See
pmFetch(3) and pmFreeResult(3) for further details.
pmFetchArchive returns zero on success.

DIAGNOSTICS
PM_ERR_NOTARCHIVE
the current PMAPI context is not associated with an archive log
