I noticed an error in and example on the man page for strncpy(). The page is http://www.kernel.org/doc/man-pages/online/pages/man3/strncpy.3.html

The error is in the section, "NOTES", specifically in the code example after the text:

      If there is no terminating null byte in the first n characters of src,
       strncpy() produces an unterminated string in dest.  Programmers often prevent
       this mistake by forcing termination as follows:

           strncpy(buf, str, n);
           if (n > 0)
               buf[n - 1]= '\0';

Substituting 1 for n and "123" for str, this would equate to:

           strncpy(buf, "123", 1);  // buf is now "1"
           if (1 > 0)
               buf[1 - 1]= '\0';                // buf is now ""
