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 a set of archive logs of performance metrics as created by
Calling pmDupContext will replicate the current PMAPI context,
returning a handle for the new context that may be used with
subsequent calls to pmUseContext(3).
Once created, the duplicated context and the original context have
independent existence, and so their instance profiles and collection
time (relevant only for archive contexts) may be independently
The newly replicated context becomes the current context.
