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  pmlog-
       ger(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.
