这错误让我很纠结，求解！

[风吹草低现羊牛]

#include <wdm.h>
#include <ntdef.h>

VOID UnLoad(PDRIVER_OBJECT DriverObject)
{
	KdPrint("xxxx");
}

NTSTATUS
DriverEntry(
    IN PDRIVER_OBJECT  DriverObject,
    IN PUNICODE_STRING RegistryPath
    )
{
   /* NTSTATUS status;*/
	DriverObject->DriverUnload = UnLoad;
    return 1;
}

TARGETNAME=wdm
TARGETPATH=obj
TARGETTYPE=DRIVER

SOURCES= firstwdm.c

这句有错
KdPrint("xxxx");
应该为
KdPrint(("xxxx"));
看一下KdPrint的宏定义就知道了。
