Hello
I have a suggestion for strncpy.

C23 draft states this caveat for strncpy.

"373) Thus, if there is no null character in the first n characters of the array pointed to by s2, the result will not be null-
terminated."

https://man7.org/linux/man-pages/man3/strncpy.3.html

"If the destination buffer, limited by its size, isn't large
enough to hold the copy, the resulting character sequence is
truncated. "

How about clarifying this as:

"If the destination buffer, limited by its size, isn't large
enough to hold the copy, the resulting character sequence is
truncated; where there is no null terminating byte in the first n
characters the result will not be null terminated. "

Kind regards, Jonny
