The process communication methods in Linux are basically inherited from the process communication methods on the UNIX platform. The Bell Labs and BSD (Berkeley Software release center at the University of California Berkeley), which have contributed

Communication between IPC processes in Android development-AIDL introduction and instance analysisI. IPC inter-process communication IPC is a general term for inter-process communication methods. Linux IPC includes the following methods. What are

Eight Methods for Process Communication in Linux: pipelines, named queues (FIFO), memory ory ing (mapped memeory), message queues ), shared memory, semaphore, signal, Socket ).(1) pipeline (pipe): the pipeline allows one process to communicate with

Signal (2) sigaction Function The sigaction function is used to check or modify the processing actions associated with the specified signal. This function replaces the signal function. # Include Int sigaction (int signum, const structsigaction *

Classic Linux kernel interview questions 1) What kernel locks does Linux have? 2) What is the meaning of the user mode and Kernel Mode in Linux? 3) How to Apply for a large kernel memory? 4) What are the main methods for inter-process communication?

At present, more and more people choose to apply Linux, but are you familiar with Linux? What kind of knowledge does Linux have? This article describes several main methods of inter-process communication in Linux, and plays a certain role in

Source: Lupa open-source community Release date:  Network Programming in Linux is divided into two parts: Server programming and client programming. Generally, a daemon process must be created before a server program receives client connection

Linux provides a variety of internal process communication mechanisms, including shared memory, memory ing files, first-in-first-out (FIFO), interfaces (sockets), and a variety of identity for synchronization. In this article, we will mainly discuss

HPD (Hot Plug detection) is designed for hot swapping in a pair of HDMI connections. Simply put, when the sender accesses the receiver, the receiver responds to the HPD signal to the sender, and then the sender starts the DDC channel to read the

Linux inter-process communication Introduction to several main methods for inter-process communication in Linux: A)Pipeline (PIPE) and famous Pipeline (Named Pipe): pipeline can be used for communications between kinship processes. Famous pipelines

Inter-process communication is to spread or exchange information between different processes. So what media can be accessed by both sides between different processes? The user space of a process is independent of each other and generally cannot be

Reprinted: http://blog.csdn.net/sunmenggmail/article/details/7888746   A large application system usually requires collaboration among many processes. The importance of communication between processes (see Linux Process Concept 1) is obvious. This

The goal of this project is to develop an online multiplayer game with as few server resources as possible, while expecting to run the game on one user's browser while allowing another player to connect. In addition, it is hoped that the program is

The means of communication under Linux is basically inherited from the process communication mechanism on UNIX platform.The process communication communication mechanism under Linux mainly includes: Pipe and well-known pipe (named pipe):

Inter-process Communication overview Process communication purposes Transferring DataA process needs to send its data to another process. The amount of data sent is between one byte and a few m bytes Sharing DataMultiple processes want

In fact, sometimes think of the Linux kernel design also contains a lot of philosophy of life, there are so many special processes in Linux, we start to see their names may also feel very surprised, but after the understanding of the principle, we
