PMNEWCONTEXTZONE(3)       Library Functions Manual       PMNEWCONTEXTZONE(3)

NAME         top

       pmNewContextZone  -  establish  a reporting timezone based on a PMAPI

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       int pmNewContextZone(void);

       cc ... -lpcp

DESCRIPTION         top

       The current reporting timezone affects the timezone used by
       pmCtime(3) and pmLocaltime(3).

       If the current PMAPI context is an archive, pmNewContextZone uses the
       timezone from the archive label record to set the current reporting

       If the current PMAPI context corresponds to a host source of metrics,
       pmNewContextZone executes a pmFetch(3) to retrieve the value for the
       metric pmcd.timezone and uses that to set the current reporting

       In both cases, pmNewContextZone returns a value to identify the
       current reporting timezone that may be used in a subsequent call to
       pmUseZone(3) to restore this reporting timezone.

DIAGNOSTICS         top

              the current PMAPI context is not valid

       other  a return value less than zero indicates a fatal error from a
              system call, most likely malloc(3)
