From 35295f190207d9001fdcf30fe76f11434691b259 Mon Sep 17 00:00:00 2001 From: Tobias Stoeckmann Date: Tue, 4 Apr 2017 21:27:31 +0200 Subject: On success, fgets always terminates the result. If fgets succeeds, then the resulting char array is always terminated by a '\0'. No need to keep extra space, therefore sizeof(buf) is the correct argument.
