A custom multi-threaded control communication method

Abstract

The invention discloses a self-defined multi-thread management control communication method. The method comprises the following steps of 1) designing a parameter structure object, embedded business parameters of the parameter structure object and two command pointer items for an entrance function of a son thread, wherein the embedded business parameters are required by a normal business design function, and the command pointer items are designed for control management of father and son threads; 2) defining and initializing two local variables in the father thread, taking addresses of the two local variables as pointers of uplink and downlink command parameters, and starting the son thread; 3) changing the values of the local variables in the father thread, wherein the local variables include the downlink command parameter, and the value change causes change of executive logic of the son thread; and 4) obtaining an introduction pointer in the son thread and changing the value of the uplink command parameter, wherein the value change causes change of code execution logic in the father thread. According to the method, the kernel resource consumption is reduced, the code packaging is relatively simple, and the real-time property is good.

Description

technical field [0001] The invention belongs to a program communication method, in particular to a multi-thread control communication method. Background technique [0002] Multithreaded programming is a software design method generally supported by various operating systems such as Windows / Linux / vxWorks, and it is also a design method supported by various development language platforms such as C / C++, Java, and C#. Management control and data communication between threads on various operating systems at the C / C++ level have similar concepts and methods, such as mutual exclusion, locking, synchronization, and waiting. In JAVA, due to the language-level multi-thread API support, the multi-thread design becomes simpler. The granularity of JAVA multi-thread control management is coarser than that of C / C++, so the flexibility is not as good as the latter. [0003] On various operating systems, use C / C++ for multi-thread programming thread control methods, especially the synchroni...
