       The  wcsncpy() function is the wide-character equivalent of the strncpy(3) function.  It copies at most n
       wide characters from the wide-character string pointed to by src, including  the  terminating  null  wide
       character  (L'\0'),  to the array pointed to by dest.  Exactly n wide characters are written at dest.  If
       the length wcslen(src) is smaller than n, the remaining wide characters in the array pointed to  by  dest
       are  filled  with  null  wide  characters.   If the length wcslen(src) is greater than or equal to n, the
       string pointed to by dest will not be terminated by a null wide character.

       The strings may not overlap.

       The programmer must ensure that there is room for at least n wide characters at dest.
