Memory for the new wide-character string is obtained with malloc(3), and should be freed with free(3).
RETURN VALUEOn success, wcsdup() returns a pointer to the new wide-character string. On error, it returns -1, with errno set to indicate the cause of the error.
- Insufficient memory available to allocate duplicate string.
