小弟我在驱动的主函数里，调用一个对象的函数出错

我在驱动的主函数里，调用一个对象的函数出错。
#include "KeApp.h"
NTSTATUS extern "C" DriverEntry(PDRIVER_OBJECT pDriverObject,PUNICODE_STRING reg_path)
{

CKEAPP KeApp;

KeApp.Init(pDriverObject,reg_path);

return STATUS_SUCCESS;

}
class CKEAPP
{
public:
void * operator new(unsigned int size);
void operator delete(void *p);
void Init(PDRIVER_OBJECT pDriverObject,PUNICODE_STRING reg_path);
};
void CKEAPP::Init(PDRIVER_OBJECT pDriverObject,PUNICODE_STRING reg_path)
{
pDriverObject->DriverUnload = KeAppDriverUnload;

}
error LNK2010: unresolved external symbol " publc": void __thiscall CKEAPP::Init(struce _Driver_object *,struct _unicode_string *) (init@Ckeapp@............)referenced in function _DriverEntry@8

[解决办法]
DriverEntry是声明成extern "C"的函数。所以，会按照C的函数调用方式进行。

试着在Init函数声明前加关键字static，改变Init函数的访问方式。

C/C++ code

class CKEAPP{public:void * operator new(unsigned int size);void operator delete(void *p);static void Init(PDRIVER_OBJECT pDriverObject,PUNICODE_STRING reg_path);};
