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.

DIAGNOSTICS
