Question: Why kilo allocating 9 bytes memory for a non-printable character?
Author: KiYugadgeterCreated Sep 22, 2016Updated Dec 21, 2020
I am reading kilo code for learning C language.
In line551, allocating 9 bytes memory for one non-printable character.
Why 9 bytes memory need for a non-printable character?
And `nonprint` variable is only initialized to 0 at line 543, and it is not assigned to other value.
So I think `nonprint` is not useful at line 551.
What's the meaning of this?
row->render = malloc(row->size + tabs*8 + nonprint*9 + 1);
