*wchar_t *_wcsdup(string) - duplicate string into malloc'd memory
*
*Purpose:
*   Allocates enough storage via malloc() for a copy of the
*   string, copies the string into the new memory, and returns
*   a pointer to it (wide-character).
*
*Entry:
*   wchar_t *string - string to copy into new memory
*
*Exit:
*   returns a pointer to the newly allocated storage with the
*   string in it.
*
*   returns NULL if enough memory could not be allocated, or
*   string was NULL.
*
*Uses:

*Exceptions:
