by s.
Memory for the new wide-character string is obtained with malloc(3), and
should be freed with free(3).
RETURN VALUE
On success, wcsdup() returns a pointer to the new wide-character string.
On error, it returns NULL, with errno set to indicate the error.
ERRORS
ENOMEM Insufficient memory available to allocate duplicate string.
