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.
