The simple answer to this first question is that a callback function isa function that is called through a function pointer.If you pass the pointer (address) of a function as an argument to another, when that pointer is used to call the function it points to it is said that a call ba...
这个被传入的、后又被调用的函数就称为回调函数（callback function）。今天给大家讲一下芯片/模块厂家...

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, int size, int elem_size, CompareFunction cmpFunc); void...

function CBFunc(Param1,Param2:integer):integer;stdcall; 以上函数为全局函数,如果要使用一个类里的函数作为回调函数原形,把该类函数声明为静态函数即可。 三: 回调函数调用调用者 调用回调函数的函数我把它放到了DLL里,这是一个很简单的VC生成的WIN32 DLL.并使用DEF文件输出其函数名 TestCallBack。实现如下: ...
