23 The __wcsstr__ function is the wide-character equivalent
24 of the __strstr__ function. It searches for the first
25 occurrence of the wide-character string ''needle''
26 (without its terminating L'0' character) as a substring in
27 the wide-character string ''haystack''.
28 !!RETURN VALUE
29
30
31 The __wcsstr__ function returns a pointer to the first
32 occurrence of ''needle'' in ''haystack''. It returns
33 NULL if ''needle'' does not occur as a substring in
34 ''haystack''.

37 Note the special case: If ''needle'' is the empty
38 wide-character string, the return value is always
39 ''haystack'' itself.
