PMDUPCONTEXT(3) Library Functions Manual PMDUPCONTEXT(3)
pmDupContext - duplicate a PMAPI context
#include <pcp/pmapi.h>
int pmDupContext(void);
cc ... -lpcp
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 archives of performance
metrics as created by pmlogger(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.
PMAPI(3), pmNewContext(3) and pmUseContext(3).
