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.
