In-Depth Exploration of Pointers in C Language
Hello everyone! Today we are going to talk about one of the most powerful yet confusing features of the C language for beginners – pointers. Through several practical examples, let’s master this core concept step by step. A pointer is essentially a variable that stores a memory address. Imagine it like the house number, telling … Read more
Implementing a HashMap in C Language
In the world of data structures, a HashMap is an efficient tool for storing and retrieving data. It stores data in the form of key-value pairs, allowing for insertions, deletions, and lookups to be performed in average constant time complexity. Today, we will implement a simple HashMap using the C programming language. 1. Introduction to … Read more

Understanding Byte Alignment in Linux
Recently, I encountered a problem where threadx running on ARM crashed when communicating with DSP using message queues (the underlying implementation is through interrupts and shared memory). During the troubleshooting process, it was found that the structure used for message passing did not consider the issue of byte alignment. Here, I will整理一下 the issue of … Read more
