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.
