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
your application must be notified. But, the implementer of the time'rs mechanism doesn't know anything about your application. It only wants a pointer to a function with a given prototype, and in using that pointer it makes a callback, notifying...

A callback function taking a member function pointer of class T can be called using a member function pointer of class T. Using a function that takes a pointer to member function callback is -in analogy to function pointers- quite simple as well: C my_c{2}; // aggregate initialization ...
typedef int (__stdcall *CompareFunction)(const byte*, const byte*); 它也导出两个叫做Bubblesort() 和Quicksort()的方法,通过按照名字实现相应排序算法,他们都具有相同的原型但提供了不同的行为。 void DLLDIR __stdcall Bubblesort(byte* array, ...

Callback是这样的一类对象(在这里不能简单的理解为"回调函数"了):你注册一个函数,以及调用它时的参数,希望在满足某个条件时,以这些注册的函数调用这个回调,完成指定的操作. 很多地方会使用到这个概念.比如,UI程序中,注册一个函数,当某个鼠标事件发生的时候自动调用;比如,创建一个线程,线程开始运行时,执行注册的...
