In C language, functions are also a type of “object”, which have addresses in memory. Therefore, it is possible to define pointers to functions, which can be used for dynamic calls, callback handling, building function tables, etc. Mastering function pointers is key to understanding the “low-level abstraction” and “modular programming” in C language. 1. Basic … Read more
Asynchronous programming can create efficient programs that are fast and resource-saving. It allows high concurrency in a single-threaded environment and can implement TCP/IP protocol stacks without an operating system. Fast and resource-efficient, it can keep power consumption at the lowest level, making asynchronous programming the best programming model for low power design. Three Realms There … Read more
Hello everyone! Today we are going to talk about a particularly practical and interesting topic—function pointers and callback mechanisms. In C++, function pointers are a tool that makes your code more flexible, allowing you to dynamically choose which function to execute at runtime. The callback mechanism is a classic application of function pointers, widely used … Read more
