Hello everyone, I am the Mixed Bag Master. queue.h is a header file in Linux and FreeBSD. FreeBSD: FreeBSD is a UNIX-like operating system. This is a very practical header file because it contains all macro definitions, making it usable not only in Linux/Embedded Linux projects but also conveniently in microcontroller projects. It implements the … Read more
In the world of the Linux kernel, data structures are like the foundation of a building, supporting the efficient operation of the entire system. Linked lists, as a flexible and commonly used data structure, play a crucial role in the kernel. Today, we will delve into the implementation of linked lists in the Linux kernel—list.h—and … Read more
Implementing Linked Lists in C: Creation, Traversal, and Operations of Singly Linked Lists In data structures, a linked list is a very important linear data structure. Unlike arrays, the elements in a linked list do not need to be stored in contiguous memory locations; instead, they are connected through pointers. This article will detail how … Read more
Follow+Star PublicAccount, don’t miss out on exciting contentSource | Internet In general embedded product design, due to cost, power consumption, etc., the selected MCU is usually resource-constrained, and the number of timers inside is also limited. In our software design, there are often various timing requirements, such as pulse output, key detection, LCD screen switching … Read more
C Language Interview: Project Experience and Code Examples Sharing In C language interviews, project experience and practical coding skills are crucial assessment components. This article will help foundational users understand relevant concepts and improve their performance in interviews through some common project cases and corresponding code examples. 1. Professional Background and Project Experience As a … Read more
Implementing Linked List Data Structure in C++ A linked list is a type of linear data structure consisting of a series of nodes. Each node contains two parts: a data field and a pointer to the next node. Unlike arrays, linked lists do not require contiguous memory space, making them more efficient for insertion and … Read more
Follow+Star Public Account Number, don’t miss out on exciting content Source | Internet As an embedded engineer, how can you write efficient and clear C language programs? You need to build the program structure using the C language’s way of thinking. You should have a solid foundation in C language algorithms to implement the program’s … Read more
1 Object-Oriented C Object-oriented languages are closer to human thinking patterns, significantly reducing code complexity while enhancing code readability and maintainability. Traditional C code can also be designed to be readable, maintainable, and of lower complexity. This article will illustrate this through a practical example. 2 Basic Knowledge 2.1 Structures In addition to providing basic … Read more
Singly Linked List The Zephyr singly linked list is implemented in the following file: zephyr/include/zephyr/sys/slist.h. Zephyr stores singly linked list data in sys_slist_t (i.e., each list element stores a pointer to the next element, rather than the data of the previous element). /** @cond INTERNAL_HIDDEN */ struct _slist { sys_snode_t *head; sys_snode_t *tail; }; /** … Read more
This article provides an overview without technical details or usage instructions. The Zephyr kernel uses a generic data structure library, which can also be utilized in applications. The data structures include: Linked List Packet Buffer Red-Black Tree Circular Buffer It is important to note that the APIs for accessing these data structures are not thread-safe. … Read more
