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 log 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.

SEE ALSO

       PMAPI(3), pmDestroyContext(3), pmDupContext(3), pmNewContext(3) and pmUseContext(3).

DIAGNOSTICS
