1. Background 1. Storytelling Previously, I shared an article about <span>unmanaged memory leaks caused by C# calling C code</span>. This was a deliberately induced positive leak. In this article, we will explore the root cause of the leak from a reverse perspective. This issue is relatively easy to handle on Windows, as many people know … Read more
Memory Management in C: Avoiding Memory Leaks and Dangling Pointers In C programming, memory management is a crucial topic. Since C provides direct manipulation of memory, programmers need to manually allocate and free memory. While this flexibility is powerful, it can also lead to common issues such as memory leaks and dangling pointers. This article … Read more
Click on the aboveblue text to follow us In embedded systems, memory resources are often very limited, and memory leaks can lead to degraded system performance or even crashes. A memory leak refers to memory allocated by a program that is not properly released, gradually exhausting available memory. As a lightweight real-time operating system (RTOS), … Read more
1. What are the methods of memory allocation in C language? ā–¨Technical Principles Explained In embedded systems, the memory allocation mechanism directly affects the stability and performance of programs. C language manages memory through the following three methods: Memory Allocation Methods Low-Level Mechanism Analysis: 1. Static Storage Area Lifecycle: Allocated at program startup, released at … Read more
Memory Leak Detection Methods in C++ In C++ programming, memory management is an important topic. Incorrect memory allocation and deallocation can lead to memory leaks, which affect the performance and stability of the program. This article will introduce several methods for detecting memory leaks in C++ programs and provide corresponding code examples. What is a … Read more
C++ Debugging Techniques and Tools Debugging is a crucial part of the software development process, especially when writing C++ code. Understanding how to effectively identify and resolve issues can significantly enhance development efficiency. This article will introduce some commonly used C++ debugging techniques and tools, along with examples demonstrating how to use them. 1. Basic … Read more
The C/C++ language differs from other languages in that it requires developers to manage memory resources themselves. Improper use of dynamic memory can easily lead to segmentation faults or memory leaks. In particular, memory leaks are often discovered only after the program has been running for a while, making it difficult for developers to locate … Read more
Click the aboveblue text to follow us Memory leaks are a serious issue in embedded system development, especially in resource-constrained environments. Unlike desktop applications, embedded systems often have strict memory limitations, where even small memory leaks can quickly lead to system crashes or functional anomalies. A memory leak refers to a situation where a program … Read more
1. Introduction Recently, various products in our department have encountered issues caused by memory leaks, specifically manifested as board resets after continuous operation for several days due to memory exhaustion. On one hand, memory leak issues are considered low-level errors, and their oversight in production can have severe consequences; on the other hand, since memory … Read more
C++ Destructor: Proper Resource Release and Object Destruction In C++, resource management is an important aspect of program design. To effectively manage dynamically allocated memory and other system resources, we need to carefully consider the lifecycle of objects. In this process, the destructor plays a crucial role. This article will provide a detailed introduction to … Read more
