Accidental opportunity, re-write a comparison of Windows socket communication based on the code, too long no contact socket and multithreading, many blog, but found that most of the content is older, so decided to write a blog, by the way to sum up their own. Content IntroductionIntroduction to basic functions of network communication C++11 multithread Introduction Socket

Java was originally introduced as a network programming language, which provides a high degree of support to the network, which makes the communication between client and server become reality, and in network programming, the socket is the most used. Like everyone familiar with the QQ, MSN has used the socket-related technology. Now let's uncover the mystery of the socket.Socket ProgrammingBasic knowledge of network (refer to computer network)about th

Process communication methodsIt is necessary to describe the communication of the process before the description of the thread communication;There are several ways to communicate between processes:(1) Pipes: Pipelines can be used to communicate between affinity processes, allowing one

Overview of inter-process communicationProcess communication has some of the following purposes:A, data transfer: A process needs to send its data to another process, the amount of data sent between a byte to a few m bytesB, shared data: Multiple processes want to manipulate shared data, a process changes the shared data, and other processes should be seen immediately.C, notification e

1. PipelinePipeline communication--can only be run on a single computer.Pipeline: Must be half-duplex communication, can only flow to One direction (specified direction);A pipeline is a concept of interprocess communication that constructs a one -way data Flow channel between processes to communicate. Data flows from one process to another through that channel in

This blog is mainly about indirect communication technology, including group communication, publish-subscribe system, Message queue, distributed shared memory, etc. Indirect communication Indirect communication is defined as an entity communicating through intermediaries in a distributed system without direct couplin

When it comes to Linux operating systems, you cannot fail to mention network technology. The Linux system itself is a network of products, it can be on the network for people to download freely, and be modified and perfected. The Linux system supports a variety of network protocols, and its shell provides powerful networking commands. These advantages enable Linux to provide a complete solution for many small and medium sized network applications. Referring to the computer network, we have to f

Why interprocess communication (IPC (inter-process communication))Data transfer: One process needs to send its data to another process, sending the amount of data between a byte and a few m bytesShared data: Multiple processes want to manipulate shared data, one process changes the shared data, and other processes should see it immediately.Notification Event: A process needs to send a message to another or

consumption. Obviously, these operations are CPU-intensive and are not worth advocating. So is there a better way to solve this kind of problem?First, only the Synchronized keyword is sufficient when the thread needs to wait for a condition before it can continue execution. Because although the Synchronized keyword can prevent concurrent updates to the same shared resource, it enables synchronization, but it cannot be used to implement message passing between threads, known as

processes on the same computer.Note: To control synchronization, and collect class CString, list, Arry, map, etc. are not safe to use in shared memoryDo not put C + + classes that have virtual functions in shared memoryDo not put MFC objects of the CObject derived class into shared memoryDo not use the "point within the shared memory" pointerDo not use the "point outside of the shared memory" pointerUsing the "based" pointer is safe, but use it carefully3 Anonymous PipelinesA pipe is a

This paper introduces the communication mechanism of socket socket based on TCP/IP protocol under Windows operating system and the knowledge and skill of multithreading programming, and gives a detailed algorithm of multi-threading method to implement concurrent communication model of multi-user and Server (c/s), finally shows the C + + An application instance written for multi-user and server
