新手求助：主应用程序调用dll回调函数问题
编译主程序时，老是报错：
cannot convert 'int (* (_closure )()()' to 'int(*)()'
type mismatch in parameter 1 (wanted 'int(*)()',got 'void')
请问各位大大，这到底是什么原因啊

C/C++ code

//主应用程序    HINSTANCE ins;     ins = LoadLibrary("./dll/dllTalk.dll");  try  {     if(ins == NULL)         throw MyException("Can't Load Library!");      FARPROC lpFarProc;                           //回调函数未成功     lpFarProc = GetProcAddress(ins,"call");     if(lpFarProc == NULL)     {         FreeLibrary(ins);         throw MyException("Can't Get dd Address!");     }     typedef int (*pfv)();     typedef void (* pt)(pfv);     pt aFunc = (pt)lpFarProc;     aFunc(test1);                             //出错在这里     if(!FreeLibrary(ins))     {         throw MyException("Can't Free!");     }  }  catch (MyException &myException)  {      ShowMessage(myException.test);            }………………int test1(){    return 0;}//dll程序extern "C" __declspec(dllexport) void __stdcall call(int (*CallBack)()){   CallBack();}
