Linux IPC (Inter-Process Communication, Inter-process Communication) pipeline learning, ipcinter-Process1. the standard Stream pipeline operation supports the file stream mode, which is used to create the pipeline linking another process. This blog introduces the function popen and pclosepopen in detail. 2. unknown pipeline (PIPE) features: 1) communication can o

Process communication refers to the exchange of information between processes. PV operation is a low-level mode of communication, high-level communication means the transmission of large amounts of data with high efficiency of the communication mode. There are three main classes of advanced

(i) communication between threads: Because multithreading shares address space and data space, communication between multiple threads is a thread of data that can be directly provided to other threads for use, Without having to go through the operating system. So the communication between the threads and synchronization of the main way is lock, signal, signal vo

Communication is purposeful, so what is the purpose of communication?1. Communication with purpose 1.1: communication with four purposes (1) describes things. (2) express emotions. (3) establish a relationship. (4) attempt. Before communication, we need to know which of the

Reflection: Language Communication and document communication in project development Problem: A mentor arranged to develop and implement some functional modules or small applications during the trial period of the company. After all, you need to add code under the framework of the entire product. After reading the source code of nearly 1 GB of the entire product, it is quite vast. Although we do not need ne

Recently, I have fully felt that,ProgramThe communication and communication skills of members are too important, or even more important than technical skills. Many programmers are used to being bored with problems. 1:There are some difficult things that cannot be discussed with the leaders.-- If you don't ask a colleague, ask a technical leader, or study it by yourself, it may be difficult for several

Next: "Architecture design: Inter-system Communication (4)--io communication model and Java Practice Medium", we continue to explain asynchronous IO7. Asynchronous IOIn the previous two articles, we explained the three IO models for blocking synchronous IO, non-blocking synchronous io, multiplexed io, and Java support for these three IO models. The main point is that the IO model is supported by the operati

Inter-process communication:# pipe: A pipe is a half-duplex mode of communication in which data can only flow in one direction and can only be used between processes that have affinity. A process's affinity usually refers to a parent-child process relationship.# famous pipe (named pipe): A well-known pipe is also a half-duplex mode of communication, but it allows

HandlerHandler is a messaging mechanism in the Android system that works against multithreaded scenarios. The message of a process is passed to the B thread for asynchronous message processing. In many cases, an action message in a worker thread that needs to update the UI is passed to the UI main thread, which implements the update UI operation.Because the worker thread and the main thread are shared address spaces, that is, the handler instance object Mhandler is on a shared memory heap betwee

Escape characters in communication protocols and escape characters in communication protocolsEscape characters in communication protocolsPurpose: make the communication content more secure and reliable in the communication protocol.For example: if you need to customize a

Basic principle * * *: Normally, a program can only access its own data, and the other processes do not communicate, each process is a separate entity, processes do not need to collaborate between the task can be completed. But as the complexity of the problem increases, a process cannot do all the work, and there must be more than one process that works together to solve the problem faster, better, and more quickly, just as collaboration between people can do much bigger things. However, for

Java concurrency: Code explanation of traditional thread-synchronous communication technology, java Communication Technology This article focuses on the code example of the traditional thread synchronous communication technology of Java concurrency, which is described as follows. Let's first look at a question: There are two threads. The sub-thread executes 10

Preface:Blog articles want to organize the logical, easy to follow their own review study and communicate with you. I don't know if you feel the same way? Sometimes busy all day, search for all kinds of information, sometimes ecstatic, sometimes depressed depressed, sometimes into the source of the horn tip, sometimes the tiger to eat the day. But every time you go through this process, when you're about to give up, it suddenly dawned on you, the problem orbug solved. So again and again and agai

Principle of synchronous communication Synchronous communication is a continuous serial transmission of data communication, one communication only one frame of information. The information frame here is different from the character frame in the asynchronous communication, an

Android Process Communication and android Process Communication I recently studied the communication between Android processes. It turns out to be used, but it is useless. Let's take a look. At the beginning, my head was so big. After watching it all night, my head became like this. It scared the baby to go to bed quickly ,, Drink tea and tell a story before talk

Synchronous communication principle Synchronous communication is a continuous serial transmission of data. Only one frame of information is transmitted at a time. The Information Frame here is different from the character frame in asynchronous communication. It usually contains several data characters. When synchronous commun
