That's a great reference page Paul, lots of useful information in the manual.
https://www.gnu.org/software/libc/manual/html_node/String-and-Array-Utilities.html

Re this man page:

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

Obsolete functions
char *strncpy(char dest[restrict .n], const char src[restrict .n],
size_t n);
Copy at most n bytes from string src to dest, returning a
pointer to the start of dest.

It could clarify
"Copy at most n bytes from string src to ARRAY dest, returning a
pointer to the start of ARRAY dest."

(caps for my emphasis in this email)

Kind regards
