A method, device and system for inter-process communication

Abstract

The invention belongs to the technical field of computers and provides a process-to-process communication method, device and system. The process-to-process communication method comprises the steps of building a first shared memory and a second shared memory according to identification of a first process and identification of a second process, wherein the identification is used for uniquely identifying one process; and conducting communication between the first process and the second process through the first shared memory and the second shared memory. The process-to-process communication method is achieved on the basis of a shared memory mechanism, connecting requests of the first process are monitored, when the first process asks for communication connection with the second process, independent shared memories are built according to identification of the process of two communication parties to achieve dynamic creation of the process-to-process communication connection, and the process-to-process communication can be achieved with high performance and high flexibility.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to an interprocess communication (InterProcess Communications, IPC) method, device and system. Background technique [0002] A process is the smallest unit of computer resource allocation. Each process has its own independent resources and is isolated from other processes. In order to enable different processes to access resources and coordinate work, the operating system provides a variety of IPC mechanisms, such as pipes , shared memory, socket, etc. [0003] Under the background of the current continuous development of computer technology, it is common for multiple processes to communicate with a main process at the same time. When the third-party applications and services of various applications and platforms communicate with each other, the communication requirements between multiple processes and the main process are very large, and the performance and flexibili...
