PMNEWCONTEXTZONE(3)      Library Functions Manual     PMNEWCONTEXTZONE(3)

NAME         top

       pmNewContextZone - establish a reporting timezone based on a PMAPI
       context

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 re‐
       porting timezone.

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

       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

       PM_ERR_NOCONTEXT
              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)
