Embodiment Construction

[0110] Embodiments of the present application are described below with reference to the drawings in the embodiments of the present application.

[0111] Before introducing the method in the embodiment of the present application, in order to facilitate the understanding of the embodiment of the present application by those skilled in the art, the related concepts involved in the embodiment of the present application are introduced first.

[0112] Process isolation is a technology designed to protect processes in the operating system from interfering with each other. This technique is to prevent process A from modifying the data in process B, so that process A does not affect the operation of process B, or even process A will destroy the operation of process B. Processes are isolated through virtual address spaces. Specifically, the virtual address space of process A is different from the virtual address space of process B, so that process A can be prevented from modifying data ...

Abstract

The invention provides an inter-process communication method and related equipment. The method comprises the steps that a first process creates a first shared memory between a second process and a third process; the second process writes first data into the first mapping area and maps the first data to the first shared memory from the first mapping area according to the first mapping relation, and according to the second mapping relation, the third process maps the first data from the first shared memory to the second mapping area so as to realize one-way communication from the second process to the third process. According to the method, the security and reliability of the inter-process communication can be improved, and the performance of the inter-process communication can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an inter process communication (inter process communications, IPC) method and related equipment. Background technique [0002] IPC is a communication method for sharing messages between one process and another process, and is mainly used for message passing between different processes in a computer system. Among them, a process is the smallest unit of computer resource allocation. Each process has its own virtual address space and is isolated from the virtual address spaces of other processes. That is to say, a process can only access its own virtual address space and cannot access The virtual address space of other processes. In order to enable different processes to access each other and coordinate their work, the operating system provides various IPC mechanisms. [0003] However, the existing IPC mechanism has problems such as low performance or low secur...
