Hi Michael, Returning to an old topic, noticed strcpy man page is different from the POSIX spec with regards to "terminating NUL character" or "null-terminated" shouldn't man pages should follow POSIX style writing "NUL"? https://man7.org/linux/man-pages/man3/strcpy.3.html https://man7.org/linux/man-pages/man3/strcpy.3p.html https://pubs.opengroup.org/onlinepubs/9699919799/functions/strcpy.html Another function even has nul in the name https://man7.org/linux/man-pages/man3/strchrnul.3.html Regards, Jonny
