输出为: simba@ubuntu:~/Documents/code/linux_programming/UNP/socket$ ./byteorder 78 56 34 12 12 34 56 78 即本主机是小端字节序,而经过htonl 转换后为网络字节序,即大端。 三、地址转换函数 前面提到的 sockaddr_in 结构体中的成员struct in_addr sin_addr表示32位的IP地址。但是我们通常用点分十进制...
一、使用alarm 函数设置超时 代码语言:cpp 复制 voidhandler(intsig){}signal(SIGALRM,handler);alarm(5);intret=read(fd,buf,sizeof(buf));if(ret==-1&&errno==EINTR)errno=ETIMEOUT;elseif(ret>=0)alarm(0);... 程序大概框架如上所示,如果read在5s内被SIGALRM信号中断而返回,则表示超时,否则未超时已...
1 year ago byKalsoom Bibi Socket programming has become an important subject in the field of computer networking. It involves establishing a connection between two nodes, server, and client to communicate with each other without any interruption. The server acts as a listener in the communication ...

Edit & run on cpp.sh What aboutreadandwritefunctions? Why is the socket being closed troughtclose(fdl);? AF_INETorAF_INET6? Should I create this struct? structsockaddr_in dir = { AF_INET, htons(15557), INADDR_ANY}; this web page, shows totally different info from what I posted?

MitchJohnson(1) Here is a sample socket programming snippet from the client side. My question revolves around the type-casting that casted sockaddr_in into sockaddr. My question is that why is that casting necessary there, what is going on there exactly?
现象:服务器端意外退出后马上重启,提示端口绑定错误,端口正在使用中。稍等一会后再次重启,可以正常运行。 可以设置socket的选项为SO_REUSEADDR,使其允许完全重复的绑定。 int rc = 1; setsockopt(fd, SOL_SOCKET, SO_REUSEADDR, (char *)&rc, sizeof(rc)); ...
Blocking 获取或设置一个值,该值指示 Socket 是否处于阻止模式。 Connected 获取一个值,该值指示 Socket 是在上次 Send 还是Receive 操作时连接到远程主机。 DontFragment 获取或设置 Boolean 值,该值指定 Socket 是否允许将 Internet 协议 (IP) 数据报分段。 EnableBroadcast 获取或设置一个 Boolean 值,该值指定 So...
