Delphi 调用 C++ 回调函数

//输入函数声明
extern "C" __declspec(dllexport) int    SetRecNotifyProc( void  (*TempRecProForPub)(TICanFrame *TempFrame),char *BusName);  

//实现
int   SetRecNotifyProc( void  (*TempRecProForPub)(TICanFrame *TempFrame),char *BusName)
{

         for (int bus=0;bus<UseCanBusArrey->Count;bus++)
         {

                TCANBUS* tempBusint=(TCANBUS*)UseCanBusArrey->Items[bus];

                if (AnsiString(tempBusint->BusName)==AnsiString(BusName))
                {
                    tempBusint->RecProForPub=TempRecProForPub;
                }
         }


}
//回调函数指针声明
     void(*RecProForPub) (TICanFrame *TempFrame);


实现

   if (RecProForPub!=NULL)
   {
         RecProForPub(TempFrame);
   }

Delphi 部分 静态调用type     TempRecProForPub=  procedure(var tempframe:TICanFrame); cdecl;var    function SetRecNotifyProc(RecProForPub :TempRecProForPub;BusName:PChar): Integer; cdecl; external 'SdcsPub.dll'name '_SetRecNotifyProc';procedure TFormDevInfo.FormCreate(Sender: TObject);var BDsNameChar:array[0..100] of char;var BusName:array[0..100] of char;useip:string ;useBusName:string ;i:Integer;begin     useip:='192.168.3.233';     useBusName:='XAYF';     StrCopy(@(BDsNameChar[0]),PChar(useip));     StrCopy(@(BusName[0]),PChar(useBusName));     // InitTest(i);     InitCanbus(@BDsNameChar[0],9908,9909,@BusName[0]);     SetRecNotifyProc(UseRecProForPub,BusName);   //  ListViewDeviceInfo.Items.Clear;   //  CreateDeiviceInfo();end;
