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

       and pmUseContext(3).
