When compiling with
-DCMAKE_BUILD_TYPE=Release
, we get a-Wstringop-truncation
warning.This is because when
strncpy
exits early because the input string is too long, it DOES NOT copy a NUL terminator. Instead, we need to manually setup a NUL terminator ourselves.Side-note, I've been trying to use NULL to denote
NULL
(aka ptr type) and NUL/␀ to denote'\0'
(aka char/byte type). That seems to be the convention for C programmers.
