pmFetchArchive − get performance metrics directly from an archive log
int pmFetchArchive(pmResult **result);
cc ... −lpcp
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.
pmFetchArchive returns zero on success.
the current PMAPI context is not associated with an archive log
