DESCRIPTION

16       An  application  using  the Performance Metrics Application Programming
17       Interface (PMAPI) may  manipulate  several  concurrent  contexts,  each
18       associated  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       Calling  pmContextUndef causes the current PMAPI context to be reset to
23       undefined state which could be use to prevent unintentional  communica‐
24       tion with PMCD.
