Thus, the NULL char has to be taken into account on strncpy. This will avoid the following compiling error: tlbie_test.c: In function 'main': tlbie_test.c:639:4: error: 'strncpy' specified bound 100 equals destination size [-Werror=stringop-truncation] strncpy(logdir, optarg, LOGDIR_NAME_SIZE); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Signed-off-by: Desnes A.
