PMDUPCONTEXT(3) Library Functions Manual PMDUPCONTEXT(3)
NAME
pmDupContext - duplicate a PMAPI context
C SYNOPSIS
#include <pcp/pmapi.h>
int pmDupContext(void);
cc ... -lpcp
DESCRIPTION
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 an archive log of performance metrics as created by pmlog-
ger(1).
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 varied.
The newly replicated context becomes the current context.
