Socket network programming, socketSocket network programming network communication three elements: IP Address [host name] Identifier of the device in the Network Local loopback address: 127.0.0.1 Host Name: localhost Port Number The logical address used to identify the process. Valid port: 0 ~ 65535 0 ~ 1024 is used or reserved by the system. Do not use port 1024 during development. Transmission Protocol [communication r

1. basic structure of socketsstruct SOCKADDRThis structure is used to store socket addresses.Data definition:struct SOCKADDR {unsigned short sa_family; /* Address family, AF_XXX */Char sa_data[14]; /* Protocol address for bytes */};Sa_family in general, are "afinet".Sa_data contains the number of addresses, ports, and sockets for some remote computers, and the data inside it is mixed in one cut. To deal with Struct sockaddr, the programmer builds anot

server-side background service. The combination of a port number and an IP address is called a network socket (socket). Java language in the implementation of C/s mode, sockets are divided into two categories: On the server side, the ServerSocket class supports the underlying network traffic; On the client side, the socket class supports the underlyin

Socket (socket) First look at the definition: typedef unsigned int u_int; typedef u_int SOCKET; Socket is equivalent to the network communication at both ends of the socket, as long as the other side of the socket and their so

Php socket programming and socket programming 1. Prerequisites I have never seen how many people use the socket module of php to do some things. Maybe everyone has positioned it within the scope of the script language, but in fact, the php socket module can do a lot of things, including ftplist, http post submission, s

SocketI. OverviewSockets are also commonly referred to as "sockets," which describe IP addresses and ports, and are a handle to a chain of communication, where applications usually make requests to the network through "sockets" or respond to network requests.Sockets originate from UNIX, and one of the basic philosophies of unix/linux is "Everything is file", and the file is operated with "open" "Read and Write" "Off" mode. Socket is an implementation

Asynchronous Client Socket Example The following example program creates a client that is connected to the server. The client is generated with an asynchronous socket, so it does not suspend execution of the client application while waiting for the server to return 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

You can connect to the destination server through an unlimited number of chainable proxies, SOCKS4 and SOCKS5 servers if a Nonymity or security is a priority. S

HP-socket In the past, a general-purpose Windows Socket TCP underlying communication component was developed for a large-scale communication project. The component code is HP-socket. NowCodeOpen it to the public, hoping to help everyone. In addition, in order to make it easier for everyone to learn HP-socket, we have

C ++ Socket programming steps and socket programming steps There are three types of socket programming: stream socket (SOCK_STREAM), datagram socket (SOCK_DGRAM), and original socket (SOCK_RAW). TCP-based

Use Socket. io to push messages in real time, and socket. io to push messages in real time. Project Background There is a social network module in a recently written project. You need to implement this function: when a user is liked, commented, or followed, the server needs to push a message to the user in real time. The final project address is https://github.com/noiron/

SIGPIPE signal in socket programming and sigpipe in socket programming I wrote a server programLinuxAnd then write the client in C ++ to perform stress testing with tens of millions of short links.However, the Server Always exits without core files. Finally, the problem is determined to call two write operations on a socket that has been closed on the peer end. T
