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
In C++, resource management is a very important topic, especially when it comes to managing system resources such as memory, files, and network connections. C++ provides powerful tools and features to help programmers manage these resources efficiently and safely, with one of the key techniques being the application of smart pointers. In this article, we … Read more
Original link: https://bbs.huaweicloud.com/blogs/355148 Sometimes you may want to analyze your program based on the following parameters: Time spent by the program in user mode Time spent by the program in kernel mode Average memory usage of the program ETC On Linux, we have a utility called time designed specifically for this purpose. The time utility … Read more
Follow Our Official Account, Don’t Get Lost on the Technical Road Introduction When running a Kubernetes cluster, it is crucial to ensure that critical Pods receive the resources they need to operate normally. This can be challenging if your cluster is heavily loaded or lacks sufficient available resources. One way to ensure that critical Pods … Read more
C++ exception handling is one of the important features for improving program robustness and maintainability. In C++, resource management is closely related to exception handling, especially in ensuring that resources are correctly released in the event of an exception. In this regard, RAII (Resource Acquisition Is Initialization) is a very important design pattern that uses … Read more
In the world of C programming, code safety and resource management have always been crucial topics. Today, we will focus on a feature that is expected to become an important part of future versions of C language: ‘defer’. We will explore how to apply this feature in existing tools and compilers, as well as its … Read more
Click the blue text above to follow us In Linux multithreading programming, specific cleanup operations can be performed when a thread terminates by registering a thread cleanup handler. This is similar to using atexit() to register process termination handlers. The thread cleanup handler is used to perform resource release or cleanup tasks when a thread … Read more
Click the blue text above to follow us Transitioning embedded SoC development from single-process multi-threaded architecture to multi-process architecture is a task that requires careful planning and implementation, especially in resource-constrained embedded systems. This architectural change is typically aimed at improving system stability, isolation, security, and concurrent processing capabilities. In a single-process multi-threaded architecture, multiple … Read more
