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 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.
