1, pipeline overview and related API application1.1 Key concepts related to pipingThe pipeline is one of the original UNIX IPC forms supported by Linux and has the following features: The pipe is half-duplex, the data can only flow in one

13. Nameless Pipe Communication programming?1. Inter-process communication:Linux, as a typical multi-process operating system, requires the communication of information between processes and processes, which requires process communications.2.

Piping ConceptsPipelines are the oldest form of interprocess communication in Unix, and we refer to a data flow from one process to another as a "pipe", the essence of which is a fixed-size kernel buffer ;such as: PS aux | grep httpd | awk ' {print $

Reprint: http://blog.ddup.us/?p=285 There are several ways to communicate interprocess communication in Linux: Pipe, FIFO, shared memory, semaphores, message queues, shared files, and so on. Pipe and FIFO are the most widely used, the difference

Let's start by talking about the general purpose of interprocess communication (IPC), such as data transfer, shared data, notification events, resource sharing, and process control. But we know that for each process the process sees a piece of

Organize from the networkUnix IPC includes: piping (pipe), named pipe (FIFO) and signal (Signal)Piping (pipe)Pipelines can be used for communication between affinity processes, and well-known pipelines overcome the limitations of pipe without name,

The operation of the operating system is to use pipelines. Pipe is actually a piece of shared memory used for interprocess communication, the process of creating a pipeline is called a pipe server, and the process connecting to a pipeline is a pipe
