Synchronizing client Sockets sample The following example program creates a client that is connected to the server. The client is generated with a synchronous socket, so the execution of the client application is suspended until the server returns a response. The application sends a string to the server and then displays the string returned by the server in the console. C# using System; using System.Net; using System.Net.Sockets; The using Sys

This time in learning Android socket programming, I am not dedicated to do the app, do is bootloader, drive, HAL, the framework of this line, that is, system building and functional optimization design. In order to get through this whole line, learn a lot of things for this, today, the Android socket learning record, to prevent such a low-level error later.I here is in the Geek Institute of the source code
Recently I am working on socket programming. I have summarized two experiences and hope to share them with you. Because it is a cainiao, I hope you can give me more advice on anything wrong. The first experience is to call a function that introduces the ws2_32.dll library before creating a new socket. Otherwise, the server cannot connect to the client. Because I used so

Use socket to implement multiple connections and ssh functions, and socket to implement multiple sshI. Preface In the previous article, we already know that the client connects to the server through socket for a data transmission. How can we implement multiple data occurrences on the client? But does the server accept multiple clients?2. Send Chinese Information
After all data operations are completed, you can call the close () function to release the socket and stop any data operations on the socket:Close (sockfd ); You can also call the shutdown () function to close the socket. This function allows you to stop data transmission in a certain direction, while data transmission in one direction continues. For example, you can close the write operation of a
