Multi-process management method, storage medium, electronic device and system

Abstract

A method for managing multiple processes is provided. The invention relates to a storage medium, an electronic device and a system, and relates to the field of control technology. The method comprisesthe following steps of: calling CreateNamedPipe function in Windows system API function to create a plurality of named pipes for communication between a main process and an auxiliary process, and each named pipe corresponds to an auxiliary process; The main process calls the function WriteFile to write the task data in the named pipe and sends the written task data to the corresponding auxiliaryprocess. The worker process calls the function ReadFile to read the task data from the named pipe; The auxiliary process executes the corresponding task based on the task data, and after the task is executed, the auxiliary process calls the function AtExit to complete its own exit. A main proces in that invention controls the task execution state of the auxiliary proces through a named pipeline, so as to ensure the normal operation of an application program under the operation condition of multiple auxiliary processes.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a multi-process management method, a storage medium, electronic equipment and a system. Background technique [0002] At present, for some service-type applications, especially for applications with independent tasks, a multi-process architecture design is usually adopted. Using a multi-process design can make the instability of a process not cause the entire program to go wrong, that is, For a service-type application, when a process exits due to a crash, other processes can continue to serve. Multi-process has stronger robustness, so as to ensure the normal operation of the application. [0003] In the actual running process, for example, a main process can be created to receive tasks, and then multiple auxiliary processes (subprocesses) can be created through the main process to complete different tasks, that is, for each received task, an auxiliary process To complete, that ...

AI Technical Summary

Problems solved by technology

In actual operation, it is not guaranteed that each auxiliary process can run stably. Because there are too many auxiliary processes running at the same time, some auxiliary processes may generate data errors halfway through the task execution, causing the application to crash. The executed tasks may cause deadlock and cause the application to freeze. In the prior art, the main process does not have a good management scheme for the auxiliary process.
