PMDUPCONTEXT(3)         Library Functions Manual         PMDUPCONTEXT(3)

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
       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.
