Problems solved by technology

[0010] In the above-mentioned existing process communication methods, pipes need names and kinship, and can only carry unformatted byte streams and buffer sizes are limited, while signals have the disadvantages of carrying small amounts of information and unreliable limitations. Shared memory needs to consider process The synchronization and mutual exclusion between them increase the complexity of the design

Abstract

The invention discloses a Linux interprocess communication method, comprising the following steps: S11: polling a message in a message queue in a core process; S12: analyzing the message in the core process and determining whether the message is event information of a registered event; S13: when determining that the message is the event information of the registered event, searching for an event management link table according to the event information, and obtaining all process numbers for monitoring the registered event; and S14: awakening all processes for monitoring the registered event according to the process number in the core process, and invoking an event processing function corresponding to the registered event in each process according to the event processing function link table. The invention realizes Linux system interprocess lightweight communication by using the event broadcast mechanism, and saves resources of the system while increasing stability of the system.

Description

technical field [0001] The invention relates to the technical field of Linux platforms, in particular to a communication method and device between Linux processes, and a process exit monitoring method. Background technique [0002] Linux is a free and open source Unix-like operating system that can be installed on a variety of computer hardware devices, such as mobile phones, tablets, routers, video game consoles, desktop computers, mainframes and supercomputers. The Linux system is a leading operating system, and the 10 fastest supercomputers in the world all run the Linux operating system. [0003] Brief introduction to the main means of centralized process communication under Linux: [0004] Pipe (pipe) and named pipe (named pipe): Pipes can be used for communication between processes with kinship relationships. Named pipes overcome the limitation that pipes have no names. Therefore, in addition to the functions that pipes have, it also allows unrelated Communication be...
