pmWhichContext - identify the current PMAPI context

#include<pcp/pmapi.h>intpmWhichContext(void);cc...-lpcp

       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.
