PMWHICHCONTEXT(3) Library Functions Manual PMWHICHCONTEXT(3)
pmWhichContext - identify the current PMAPI context
#include <pcp/pmapi.h>
int pmWhichContext(void);
cc ... -lpcp
An application using the Performance Metrics Application Program‐
ming Interface (PMAPI) may manipulate several concurrent contexts,
each associated with a source of performance metrics, e.g. pmcd(1)
on some host, or an archive of performance metrics as created by
pmlogger(1).
pmWhichContext returns a handle for the current PMAPI context,
that may be used in the associated PMAPI routines that require a
handle to identify a PMAPI context.
PM_ERR_NOCONTEXT
no current context
PMAPI(3), pmDestroyContext(3), pmDupContext(3), pmNewContext(3)
and pmUseContext(3).
