#include <wchar.h>
wchar_t *wcsstr(
const wchar_t *s1,
const wchar_t *s2);

Specifies the wide-character string being searched. Specifies the wide-character substring to be located.
The wcsstr() function locates the first occurrence in the wide-character string pointed to by the s1 parameter of the sequence of wide characters in the wide-character string pointed to by the s2 parameter, excluding the terminating null wide character.
Upon successful completion, the wcsstr() function returns a pointer to the located wide-character substring or a null pointer when the substring is not found. If the s2 parameter points to a wide-character substring having 0 (zero) length, the wcsstr() function returns the entire wide-character string pointed to by parameter s1.
[Digital] On error, the function returns a null pointer.
