警告：从不兼容的指针类型 [-Wincompatible-pointer-types] 传递‘accept’的参数 2

Question

我收到警告：从不兼容的指针类型 [-Wincompatible-pointer-types]

传递‘accept’的参数 2

为什么会出现此错误？

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

Answer 1

根据https://pubs.opengroup.org/onlinepubs/009695399/functions/accept.html，accept 函数的第二个参数接收类型struct sockaddr *。您可能想要进行转换：&client_address 到 (struct sockaddr *)&client_address
