17 character string pointed to by ws1 of the sequence of wide characters
18 (excluding the terminating null wide character) in the wide-character
19 string pointed to by ws2.

22 Upon successful completion, wcsstr() shall return a pointer to the
23 located wide-character string, or a null pointer if the wide-character
24 string is not found.
