The value of ESP was not properly saved across a function c

//定义指针函数typedef int(*DLLFUNC)(int,int);int main(void){DLLFUNC dllfunc;HINSTANCE hinstance = LoadLibrary("main.dll");//try//{if(hinstance != NULL){dllfunc = (DLLFUNC)GetProcAddress(hinstance,"Max");if(dllfunc != NULL){cout << dllfunc(2,9) << endl;}}//}catch(exception & ex)//{FreeLibrary(hinstance);//}//cout << Min(199,299) << endl;//cout << Max(199,299) << endl;return 0;

}

动态调用dll函数的时候，提示Run-Time Check Failure #0 – The value of ESP was not properly saved across a function call. 错误

原因：因为调用的dll采用的是_stdcall调用方式，，c++默认是使用的_declspec导致，

修改指针函数为_stdcall . typedef int(_stdcall * DLLFUNC)(int ,int);

最重要的是今天的心。
