Socket asynchronous communication learning 3. socket Asynchronous Communication Next, the client uses the synchronous receiving mode. In the SocketClient project, a new SynServer class is created to store the socket server code. Similar to AsynServer, there are four main methods: There is a global socket, which is used

Socket programming practices in Linux (5) solutions for setting socket I/O timeout (1) Use the alarm function to set timeout #include unsigned int alarm(unsigned int seconds); Its main function is to set a signal transmission alarm. The signal SIGALRM is sent to the current process after the specified number of seconds in seconds. If the alarm function is called again within the scheduled uncomp

Since I published two articles on the implementation of the Windows Socket communication component, I have received comments from many readers, hoping to share the complete source code. At this time, this seat does not harm you. The complete code of the server component and client component is provided here. In addition, it took a little time to carefully prepare two test cases for readers to learn and understand, one for functional testing (TestEcho)
