       The  wcsdup()  function  is  the  wide-character  equivalent of the strdup(3) function.  It allocates and
       returns a new wide-character string whose initial contents is a duplicate of  the  wide-character  string
       pointed to by s.

       Memory for the new wide-character string is obtained with malloc(3), and should be freed with free(3).

ENOMEM Insufficient memory available to allocate duplicate string.
