In the call to accept(), the server is put to sleep and when for an incoming client request, the three way TCP handshake* is complete, the function accept () wakes up and returns the socket descriptor representing the client socket. The call to accept() is run in an infinite loop so ...

编译运行server,在两个终端里各开一个client与server交互,可以看到server具有并发服务的能力。用Ctrl+C关闭server,然后再运行server,此时client还能和server联系上。和前面TCP程序的运行结果相比较,我们可以体会无连接的含义。udp 协议来说,server与client 的界限更模糊了,只要知道对等方地址(ip和port) 都可以主动发数据。

Server Side Socketing /服务器端套接字 For a server to accept connections from the outside world, first it opens a ServerSocket on a port, but not connected to any client in particular. 对于一个接收外部连接的服务器,首先在某个没有连接任何客户端的端口上开启一个serversocket,代码如下 ...
udp 协议来说,server与client 的界限更模糊了,只要知道对等方地址(ip和port) 都可以主动发数据。 需要C/C++ Linux服务器架构师学习资料加qun获取(资料包括C/C++,Linux,golang技术,Nginx,ZeroMQ,MySQL,Redis,fastdfs,MongoDB,ZK,流媒体,CDN,P2P,K8S,Docker,TCP/IP,协程,DPDK,ffmpeg等),免费分享 二、UDP编程...

Byte-swapping problems occur only when interpreting network addresses. For example, the following code formats a TCP or UDP port: printf("port number %d\n", ntohs(sp->s_port));On machines that do not need these routines, the routines are defined as null macros. Client-Server Programs...
The following code is an example of an SSL server authentication using ICryptService: public void OnSSLServerAuthenticate(out X509Certificate2 certificate, out bool clientAuthenticate, ref bool checkRevocation) { //--- Set server certificate, client //--- authentication and certificate revocation...
