/*QWchar_t*/ *wcsstr( /*QWchar_t*/ *dest, const wchar_t *src );

(since C23)

# Parameters

# 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]);
        }
    }
