Thread Local Storage in C Language Concurrency: pthread_key_create In multithreaded programming, managing data sharing between threads is an important issue. Especially in C language, due to its direct memory manipulation characteristics, using data appropriately can become complex. In this article, we will delve into “Thread Local Storage” and how to implement this feature using the … Read more
Introduction In embedded development, have you ever encountered a scenario where the value of a global variable suddenly changes? The interrupt service routine has modified it, yet the main program continues to read the old value. Even more frustrating, these issues are often difficult to reproduce, making debugging feel like “catching ghosts.” The root cause … Read more
Click the blue text above to follow us. In Linux, a Read-Write Lock provides a synchronization mechanism that allows multiple threads to read shared resources concurrently, but only one thread can perform write operations on that resource. Compared to mutexes or spinlocks, read-write locks offer higher concurrency because they have three states: read-locked state, write-locked … Read more

Basic Concepts of Multithreading In C++, multithreading allows us to split a program into multiple threads that can run simultaneously. Each thread has its own execution path, and they can share resources of the process, such as memory space, file descriptors, etc. This is different from Python’s multithreading, where due to the Global Interpreter Lock … Read more
