NAME

       pmContextUndef - change current PMAPI context

C SYNOPSIS

       #include <pcp/pmapi.h>

       void pmContextUndef(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
       pmlogger(1).

       Calling  pmContextUndef causes the current PMAPI context to be reset to
       undefined  state  which  could  be   use   to   prevent   unintentional
       communication with PMCD.
