Embodiment Construction

[0020] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] like figure 1 , 2 As shown, the present invention provides a pipeline-based multi-process message communication method.

[0022] For the server side, that is, the message center, first perform the following initialization processing:

[0023] Initialize the client queue lock, and the information registered by the client (that is, the process) will be saved and maintained in the queue;

[0024] Initialize and delete the queue lock. After the client exits or closes, its registration information is moved to the queue;

[0025] The message center maintains the client queue and deletes the client queue in the form of a pointer queue. Each queue node stores the registere...

Abstract

The invention relates to the technical field of windows inter-process communication, and discloses a pipeline-based inter-process message communication method, which comprises the following steps that: 1, a process is registered in a message center and transmits process information, wherein the message center is used for processing a service program of the process, and the process information comprises a message identifier; and 2, the message center transmits a message corresponding to the message identifier to the process. In the communication process of the steps 1 and 2, the process and the message center communicate with each other by using a pipeline. By the method, the inter-process communication can be simply realized.

Description

technical field [0001] The invention relates to the technical field of windows inter-process communication, in particular to a pipeline-based multi-process inter-process message communication method. Background technique [0002] A process is a program loaded into memory and executed independently. Each process has its own private process space and is invisible to other processes. To exchange data between these independent processes, an inter-process communication mechanism is used. Through this inter-process communication mechanism, a process transmits control information to other processes, or exchanges data with other processes, but this communication is single and uncontrollable. For example, there is a communication requirement between process a and process b, and there is no communication requirement between process c and a and b, but process c needs to pay attention to the communication status of processes a and b in order to make corresponding processing. In this cas...
