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 pmDupContext will replicate the current PMAPI context, return‐
23 ing a handle for the new context that may be used with subsequent calls
24 to pmUseContext(3).
25
26 Once created, the duplicated context and the original context have
27 independent existence, and so their instance profiles and collection
28 time (relevant only for archive contexts) may be independently varied.

30 The newly replicated context becomes the current context.
