Subject: (my_strftime): If the underlying strftime returns 0
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=077c39d9c71c304f77aee30c1982cb7c401e3065;p=pspp

(my_strftime): If the underlying strftime returns 0
(which shouldn't happen), generate nothing instead of returning 0
immediately, so that nstrftime (NULL, ...) doesn't return 0.
