pipelines are a basic way of interprocess communication, and pipelines are divided into two types, anonymous pipes and named Pipes, first of all . name PipeAnonymous pipe (pipe)#include When the pipe is called, a buffer is opened in the kernel, using fileds as the output, fileds is the write port, and the call returns 0 on success, and 1 when the failure oc
Named pipes are information transfers from one process to another using kernel objects. Unlike a typical pipeline, named pipes can be called by different processes in different ways (across permissions, across languages, across platforms). As long as the program knows the name of the

Previously, the mail slots have been used for interprocess communication: http://www.cnblogs.com/jzincnblogs/p/5192654.html, which uses named pipes for interprocess communication.Unlike postal slots, named pipes transfer data between processes in a connected and reliable way, so the
In the previous article--linux interprocess communication--Using anonymous pipes, we saw how to use anonymous pipes to pass data between processes, as well as seeing a flaw in this approach, which is that these processes are initiated by a common ancestor process, This brings inconvenience to us in exchanging data between unrelated processes. Another way of communicating the process,

Why do you have a named pipeThe generation of anonymous pipelines overcomes a small amount of data transfer between related processes, but Anonymous pipelines cannot transmit data between processes that are not related . To resolve the problem, a named pipe appears.Named pipes are also allocated a block of storage in the kernel, andis associated with a file name
First, Named Pipes (FIFO)One limitation of anonymous pipeline applications is that they can only communicate between processes that have a common ancestor (affinity).If we want to exchange data between unrelated processes, you can do this with a FIFO file, which is often referred to as a named pipe.Named pipes can be c
One disadvantage of the pipeline is that there is no name, so it can only be used for inter-process communication with affinity, and the named pipe (named pipe or FIFO) solves this problem.
FIFO provides a path name associated with it, stored in the file system as a FIFO file. The pathname in the file system is global and can be accessed by each process, so a path name in the file system can b
How does the internal pipeline implement-size, organization, ring queue?I. There are several ways of interprocess communication, this article mainly explains the understanding of pipelines. Pipelines are divided into anonymous pipes and named pipes. (1) piping (pipe): also known as anonymous pipes. is a half-duplex m

For the basic usage of pipelines, see system. Io. Use pipelines for inter-process communication (system. Io. Pipes ).
This section describes how to use named pipes. In this example, several clients obtain the newly generated int type ID through a server.
Server Function: when the client requests a new ID, it increases the existing ID by 1 and returns it to the cl
Named pipes (named pipe)Because of the fork mechanism, pipelines can only be used between parent and child processes, or between two child processes that have the same ancestor (between processes that are related to each other). To solve this problem, Linux provides a FIFO way to connect the process. FIFO is also called named
A typical pipeline can only connect to related processes. A regular pipeline is created by the process and closed by the last process.Named pipes can be used to connect unrelated processes and can be independent of the existence of a process.The following is a server and client program implemented by the Shell for a FIFO (named pipe)-based time/date service.1, server program#！ /bin/sh#time ServerWhile True;
Here is the. NET Named Pipes solution.
Namedpipenative: This class communicates with Kernal32.dll to implement named Pipes, which contain some common methods and constants.
