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 a set of archive logs 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.
