Its items is a stringlist type thing. Each element is a string and can save an object at the same time; when used, a subtype of an object is often defined, and a new object is added to items. Finally, the release of this object is managed.Open

The FreeRTOS kernel Scheduler uses a data structure that lists (list) extensively. If we want to explore the operating mechanism behind FreeRTOS, the first stumbling block is the list. For the FreeRTOS kernel, the list is the most basic part of it. In this chapter we focus on the structure of lists and list items, as well as the operation functions, and the knowledge points in this chapter are used when explaining task creation in the next chapter.Lis
