This paper gives a very useful small example of TCP communication between the server and the client. Concrete implementation is very simple, but usually write a similar program, the specific steps are often forgotten, but also always check, for the time being written down, convenient for later reference.(1) client program, write a file client.c, the content is as follows:#include #include#include#include#in

Network Application and client software
When it comes to mobile web apps, the first thing we think about in the last few years is WAP applications. Recently with the market on the mobile phone's programmable ability more and more strong, mobile phone software development platform and industrial chain gradually mature, mobile phone network application software gradually more up, such as Mobile QQ, PICA, palm communication and so on. These
The Java language constructs a network server, realizes the communication between the client and the server, realizes the client to have the independent thread, does not interfere with each other.
The basic steps of using multithreading to realize communication between server and multithreading

2. Principle of realization:
1. The main process establishes the TCP listening service and initializes a variable Talkchan: = Make (Map[int]chan string)
2, when the main process accept connection request, use go to start a coprocessor to maintain the connection with the client, the Taokchan into the association Chengri

The previous chapter describes some of the basic issues with installation settings and the use of a S p, as well as the built-in objects it provides. This chapter will further examine the two most commonly used objects. Between browsers (or other user agents) and our B servers, the exchange of information that occurs in requests and responses can be accessed and managed through two built-in objects in the ASP, which are called request
Linux is known for its source code, and its stability and reliability in the field of the operating system, the network application technology is more widely used. It has been one of Windows ' most important rivals for a long time. With the advent of the Internet era, this advantage of Linux has become more prominent. This article will discuss how to use the socket to implement client/server communication in Linux environment.
