wcsstr

Defined in header <wchar.h> 
wchar_t *wcsstr( const wchar_t *dest, const wchar_t *src );
+		 (1) (since C95) 
/*QWchar_t*/ *wcsstr( /*QWchar_t*/ *dest, const wchar_t *src );
+		 (2) (since C23)
+1) Finds the first occurrence of the wide string src in the wide string pointed to by dest. The terminating null characters are not compared.
+2) Type-generic function equivalent to (1). Let T be an unqualified wide character object type. If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if (wcsstr) or a function pointer is used), the actual function declaration (1) becomes visible.

Parameters

+ + +
dest - pointer to the null-terminated wide string to examine
src - pointer to the null-terminated wide string to search for

Return value

Pointer to the first character of the found substring in dest, or a null pointer if no such substring is found. If src points to an empty string, dest is returned.

+

Example

#include <stdio.h>
+#include <locale.h>
+#include <wchar.h>
+ 
+int main(void)
+{
+    setlocale(LC_ALL, "ru_RU.UTF-8");
+ 
+    wchar_t str[5][64] = {
+        L"Строка, где есть подстрока 'но'.",
+        L"Строка, где такой подстроки нет.",
+        L"Он здесь.",
+        L"Здесь он.",
+        L"Его нет."
+    };
+ 
+    for (size_t i = 0; i < 5; ++i) {
+        if (wcsstr(str[i], L"но")) {
+            wprintf(L"%ls\n", str[i]);
+        }
+    }
+}

Output:

+
Строка, где есть подстрока 'но'.
