cpp handshake

TCP isHost LayerTo provide reliable connection services, using three-way handshake to confirm the establishment of a connection: Each TCP connection requires three phases:Connection establishment, data transmission, and connection release. The "three-way handshake" occurs in the connection establishment phase. Three-way handshake (three times

Compiler built-in macros:We first introduce several compiler built-in macro definitions, these macro definitions can not only help us to complete the cross-platform source code writing, flexible use can also skillfully help us to output very useful debugging information.There are several standard scheduled macros (also commonly used) in the ANSI C standard:__LINE__: Inserts the current source code line number in the source code;__FILE__: Inserts the current source filename in the source file;__D

Install Gtkmm 1. First install dev-cpp 2. then install the latest gtkmm2.4 from http://www.pcpm.ucl.ac.be /~ Gustin/win32_ports/index.html The development environment without gtk2.4 is automatically detected during the installation process, and the installation program is automatically downloaded. Note: Install both environments in the main directory of dev-cpp, for example, d:/dev-

The TCP creation process and the link-dismantling process are created automatically by the TCP/IP protocol stack relative to the socket developer. So developers do not need to control this process. But it is very helpful to understand the TCP underlying operating mechanism. And for the network protocol engineers and so on, almost the content of the test. The company's enthusiasm for this problem is:-) to my surprise. Sometimes in the morning before the interview to emphasize this question, and r

First, we can put everything in a. cpp file, which the compiler compiles into. obj, the compilation unit. one. cpp corresponds to one. obj and then links all. obj (through a program called a linker) to form an. exe, which is a program. if one. CPP uses another. CPP-defined function, just write its function decla

Three-time handshake (three times handshake;three-way handshake) so-called "three-time handshake" that is, the amount of data sent each time is how to track the data segment sent and received synchronization, based on the amount of data received and determined the number of data and data sent, When you have finished re

TCP Three handshake (connection established) and four waves (close connection) Reference: Http://course.ccniit.com/CSTD/Linux/reference/files/018.PDF http://hi.baidu.com/raycomer/item/944d23d9b502d13be3108f61 To establish a connection: Understanding: Traffic control for windows and sliding Windows TCP TCP uses a window mechanism for flow control what is a window. When a connection is established, each end allocates a buffer to store the received data

Json-cppis an object-oriented JSON library developed using C + +.Core Data structuresReader is a reader of json-cpp data that can read JSON data from a file stream, using the following interface:Boolparse (const std::string document,Value root,BOOL collectcomments = TRUE);Boolparse (Std::istream is,Value root,BOOL collectcomments = TRUE);Parse all the JSON into the value result.Value is the result of JSON parsing, which is used key-value to represent

Differences between header files and source files First, we can put everything in a. cpp file. Then the compiler will compile this. cpp into. obj. What is obj? It is a compilation unit. A program can be composed of a compilation unit, It can also contain multiple compilation units. If you don't want to make your source code hard to read, Please use multiple compilation units. (A function cannot be placed in

characters, so fill the bit so that the header length becomes the whole word count.Data: The data portion of the TCP message segment is optional. When a connection is established and a connection is terminated, the message segments exchanged by both parties are only TCP headers. If a party has no data to send, it also uses the header without any data to confirm the received data. In many cases where the timeout is processed, a segment of the message without any data is also sent.TCP Three-time
