DESCRIPTION

16       An  application  using  the Performance Metrics Application Programming
17       Interface (PMAPI) may manipulate several concurrent contexts, each  as‐
18       sociated  with  a  source  of performance metrics, e.g. pmcd(1) on some
19       host, or an archive log of performance metrics  as  created  by  pmlog‐
20       ger(1).
21
22       pmWhichContext returns a handle for the current PMAPI context, that may
23       be used in the associated PMAPI routines that require a handle to iden‐
24       tify a PMAPI context.
