From 42fc76f74c74a5beb3ed5569b6ac76f02023ccbc Mon Sep 17 00:00:00 2001 From: araujo Date: Fri, 15 Apr 2016 04:10:47 +0000 Subject: Use NULL instead of 0 for pointers. fgetln(3) will returns NULL if cannot get a line from a stream. strsep(3) it will returns NULL if the end of the string was reached. jemalloc(3) malloc will returns NULL if it cannot allocate memory. fgetln(3) it will returns NULL if it cannot get a line from a stream.
