PMWHICHCONTEXT(3)          Library Functions Manual          PMWHICHCONTEXT(3)

NAME
       pmWhichContext - identify the current PMAPI context

C SYNOPSIS
       #include <pcp/pmapi.h>

       int pmWhichContext(void);

       cc ... -lpcp

DESCRIPTION
       An application using the Performance Metrics Application Programming
       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.

DIAGNOSTICS
       PM_ERR_NOCONTEXT
              no current context
