One reason to use callbacks is to write 通用的 code which is independant from the logic in the called function and can be reused with different callbacks. Many functions of the standard algorithms library <algorithm> use callbacks. For example the for_each algorithm applies an unary callback to...
A callback is a function (i.e., subroutine in the code) passed to other functions as an argument to be called later in program execution. Callback functions can be implemented using different language-specific tools, but in C++, all of them are known as callable objects. Callable objects ...
A callback function in C++ is a function that is passed as an argument to another function. The receiving function can then call (or “callback”) the provided function at a specific point, allowing for dynamic execution of behavior. Callback functions are widely used in event-driven programm...

本文在 三方库移植之NAPI开发1—Hello OpenHarmony NAPI 的基础上修改hellonapi.cpp、index.ets,接着学习NAPI异步模型的Promise、Callback方式。 本文共有三个示例,分别是Callback 异步接口示例、Promise 异步接口示例、规范异步接口示例。在本文末尾的资源中提供了这三个示例的源代码,读者可以下载在开发板上运行。
