26 The wcsstr() function locates the first occurrence in the wide-charac‐
27 ter string pointed to by ws1 of the sequence of wide-characters
28 (excluding the terminating null wide-character) in the wide-character
29 string pointed to by ws2.
30
32 On successful completion, wcsstr() returns a pointer to the located
33 wide-character string, or a null pointer if the wide-character string
34 is not found.

37 If ws2 points to a wide-character string with zero length, the function
38 returns ws1.
