listen function

The first parameter of the Listen function is the socket type, the function is to establish a listener on the socket handle, as to whether there is a client connection in, it is necessary to accept the function to check, the first parameter of the

To understand the backlog argument, we must realize, a given listening socket, the kernel maintains the queues:To understand the meaning of the backlog parameter, we must understand that for a listening socket,kernel maintainer two queues:1.An

Function Prototypes:int Listen (int int. Backlog);When the server programming, often need to limit the number of connections to the client, the following is the problem analysis and solutions:Only TCP UDP is discussed below (rarely used to listen

Problem Description: I would like to ask you prawns, the parameters of the Listen function means: 1, how many customers can link to this service socket 2, through the Connect function to link the service socket, and is in the waiting service

First read this article:Http://www.cppblog.com/thisisbin/archive/2010/02/07/107444.htmlIt said it would maintain two queues, established and SYN_RCVD. The length specified by Back_log is the sum of two queues (multiplied by a factor)When the

Http://www.douban.com/note/337457460/?type=like There's a parameter in the listen. Backlog specifies how many client-side connection requests Tcpsever can accept at the same time, and when this number is exceeded the server rejects the clients '

TCP-based network programming is divided into two parts: Server side and client, and the Common Core steps and processes are as follows.Connect () functionFor the client's connect () function, the function for the client to actively connect to the

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

Listen function Summary: The LISTEN function uses an active connection socket interface to become a connected socket interface, which allows a process to accept requests from other processes, thus becoming a server process. In TCP server programming,

I read WinSock programming in "Windows programming" compiled by instructor Wang Yanping. I will sort it out here. U_short htons (u_short hostshort) // convert the byte sequence of a u_short type from the host to the TCP/IP network byte

2. network socket programming in the embedded operating system uClinuxNetwork socket data transmission is a special type of I/O, and socket is also a file descriptor. Socket also has a function call similar to opening a file. The socket () function

What is socket 　　A socket interface is an API of a TCP/IP network. A socket interface defines many functions or routines. programmers can use it to develop applications on a TCP/IP network. To learn TCP/IP network programming on the internet, you

The hidden Console window is invalid (Continued 1). the console window ] : Remotely control hosts through ports. After the program runs, the program automatically opens port 999 of the local machine, and other computers can operate on the local

Socket interface (socket interface) is a set of functions that are combined with UNIX I/O functions to create network applications. Socket interfaces are implemented on most modern systems, including all UNIX variants, Windows, and the Macintosh.1.

Basic operation of Socket: (1) socket () function: (2) Bind () function: (3) Listen (), connect () function; (4) The Accept () function; (5) The Send and receive functions in the socket: (6) The Close () function: (7) The socket function is called
