NAME¶pmWhichZone - return current reporting timezone
C SYNOPSIS¶#include <pcp/pmapi.h>
int pmWhichZone(char **tz);
cc ... -lpcp
DESCRIPTION¶The current reporting timezone effects the timezone used by pmCtime(3) and pmLocaltime(3).
pmWhichZone returns the handle of the current timezone, as previously established by a call to pmNewZone(3) or pmNewContextZone(3). If the call is successful (i.e. there exists a current reporting timezone) then a non-negative integer is returned and tz is set to point to a static buffer containing the timezone string itself.
SEE ALSO¶PMAPI(3), pmCtime(3), pmLocaltime(3), pmNewContextZone(3), pmNewZone(3) and pmUseZone(3).
DIAGNOSTICS¶A return value less than zero indicates there is no current reporting timezone.
