NAME top

 pmDupContext - duplicate a PMAPI context

C SYNOPSIS top

 #include <pcp/pmapi.h>
 int pmDupContext(void);
 cc ... -lpcp

DESCRIPTION top

 An application using the Performance Metrics Application Program‐
 ming 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 archives of performance metrics as cre‐
 ated by pmlogger(1).
 Calling pmDupContext will replicate the current PMAPI context, re‐
 turning a handle for the new context that may be used with subse‐
 quent calls to pmUseContext(3).
 Once created, the duplicated context and the original context have
 independent existence, and so their instance profiles and collec‐
 tion time (relevant only for archive contexts) may be independent‐
 ly varied.
 The newly replicated context becomes the current context.

 PMAPI(3), pmNewContext(3) and pmUseContext(3).
