这个驱动该如何写_驱动开发

这个驱动该怎么写？
小弟最近看了Windows驱动开发~~试着写一个HelloWorld级别的驱动,MSDN中如是写道

C/C++ code

/*To define a DriverEntry callback routine, you must first provide a function declaration that Static Driver Verifier (SDV) and other verification tools require, as shown in the following code example:*/DRIVER_INITIALIZE DriverEntry;/*Then, implement your callback routine as follows:*/NTSTATUS   DriverEntry(     _In_ struct _DRIVER_OBJECT  *DriverObject,    _In_ PUNICODE_STRING  RegistryPath     )  {      // Function body  }

我如是写到

C/C++ code

DRIVER_INITIALIZE DriverEntry;extern "C" NTSTATUS  DriverEntry(__in PDRIVER_OBJECT pDriverObject,__in PUNICODE_STRING pRegistryPath )

然后输入build就提示出错： Error C2732: linkage specification contradicts earlier specification
for 'DriverEntry'
表示不理解，哪里错了？？？
