警告：從不兼容的指針類型 [-Wincompatible-pointer-types] 傳遞“接受”的參數 2

Question

我收到警告：從不兼容的指針類型 [-Wincompatible-pointer-types] 傳遞“接受”的參數 2

為什么我會收到此錯誤？

        if(s = accept(ls, &client_address, &client_address_len)<0);
        {
            perror("Error: accepting failed!!");
            exit(1);
        }

Answer 1

According to https://pubs.opengroup.org/onlinepubs/009695399/functions/accept.html , the second argument of accept function receives a type of struct sockaddr * . 您可能想要進行轉換： &client_address到(struct sockaddr *)&client_address
