According to the understanding of beginners, the task of return is to return the corresponding parameter, which is further processed in the outer function. In fact, the usage of return is not limited to this. Returning parameter values from the called function This type of application is the most common, usually in a function with … Read more
Introduction In the field of image processing, performance and simplicity are always the goals pursued by developers. Today, we introduce an open-source project—PlutoFilter—which is a lightweight, high-performance, and feature-rich image filter library. It is written in pure C language, consists of a single header file, and does not use dynamic memory allocation at all, making … Read more
Recently, I came across a very interesting term “callback hell”, which refers to the endless nesting of callback functions that ultimately leads to stack overflow and deadlock. The manifestation of this is multiple layers of nested function pointer callbacks, resulting in poor code readability and maintenance difficulties.Below is a simple example simulating asynchronous file reading … Read more
Scan to follow Chip Dynamics , say goodbye to “chip” congestion! Search WeChatChip Dynamics Hello everyone! Today we will talk about a small technique in C language that is both efficient and easy to “misfire”—the Inline Function! Have you ever encountered a situation where you wrote a super simple function, but the overhead of calling … Read more
In data structures, linked lists are a very important linear data structure. Unlike arrays, linked lists do not require a predefined size and can dynamically increase or decrease in elements. In this article, we will detail how to create and operate on singly linked lists in C. What is a Singly Linked List? A singly … Read more

In network programming, UDP (User Datagram Protocol) is a connectionless transport layer protocol. Unlike TCP, UDP does not guarantee the order of packet delivery and does not provide a retransmission mechanism, making it suitable for scenarios that require high speed but low reliability, such as video streaming and online gaming. This article will introduce how … Read more
In modern computer networks, a socket is the fundamental interface for network communication. Through sockets, programs can transfer data between different hosts. This article will introduce how to implement simple network programming using C, including creating a server and a client. 1. Introduction to Sockets A socket is a mechanism for inter-process communication that provides … Read more
In C programming, memory management is a crucial topic. Programmers need to use the heap and stack appropriately to optimize memory allocation, thereby improving program performance and stability. This article will detail these two memory allocation methods and provide code examples to help readers understand how to optimize in practical programming. 1. Stack 1.1 What … Read more
Some textbooks describe pre-increment/decrement and post-increment/decrement as follows: Note: Within an expression, the increment/decrement operators may behave differently as part of the operation. If the increment/decrement operator is placed before the variable, the increment or decrement operation is completed before the variable participates in the expression; if the operator is placed after the variable, the … Read more
