The strncmp() function shall compare not more than n bytes
(bytes that follow a null byte are not compared)
from the array pointed to by s1 to the array pointed to by s2.
In particular the second line.
Similarly C11 7.24.4.4:
The strncmp function compares not more than n characters (characters that follow a
null character are not compared) from the array pointed to by s1 to the array pointed to
by s2.
Similarly C99.
