Описание (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.
