2015华为软赛（二）——socket链接

点滴记录总结，一天一打鸡血。

2015年5月华为组织了一次软件精英挑战赛，赛题是德州扑克手牌AI~

关于socket通信之前写过一篇文章：http://blog.csdn.net/lh648365878/article/details/45716681

client端的主要过程如下：

1. 创建socket，返回socket描述符sockfd
2. 设置属性，可以设置端口为reuse模式
3. 使用bind对客户端ip、端口进行绑定
4. 将服务器端的ip和端口绑定（视赛制需求，一般不需要）
5. 连接

WriteLog函数用于服务端记录输出，方便调试~

    struct sockaddr_in c_addr, s_addr;    bzero(&c_addr, sizeof(struct sockaddr));    bzero(&s_addr, sizeof(struct sockaddr));    /* set client_addr */    c_addr.sin_family = AF_INET;    c_addr.sin_port = htons(atoi(client_port));    if (inet_aton(client_ip, (struct in_addr *)&c_addr.sin_addr.s_addr) == 0) {        //WriteLog(client_log, "wrong client_ip!\n", num);        exit(1);    }    /*create socket*/    int sockfd = socket(AF_INET, SOCK_STREAM, 0);    if (sockfd < 0) {        //WriteLog(client_log, "socket create error!\n", num);        exit(1);    }    /*SO_REUSEADDR */    int reuseFlag = 1;    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &reuseFlag, sizeof(reuseFlag)) == -1) {        //WriteLog(client_log, "setsockopt so_reuseaddr error!\n", num);        exit(1);    }    /*bind client socket */    if (bind(sockfd, (struct sockaddr*)&c_addr, sizeof(struct sockaddr)) == -1) {        //WriteLog(client_log, "bind client error!\n", num);        exit(1);    }    /*set server_ip */    s_addr.sin_family = AF_INET;    s_addr.sin_port = htons(atoi(server_port));    if (inet_aton(server_ip, (struct in_addr *)&s_addr.sin_addr.s_addr) == 0) {        //WriteLog(client_log, "wrong server_ip!\n", num);        exit(1);    }    /* connect to server */    while (connect(sockfd, (struct sockaddr*)&s_addr, sizeof(struct sockaddr)) == -1);    //WriteLog(client_log, "connect success!\n", num);
