DeviceIoControl问题

驱动：
RtlInitUnicodeString(&FilDevName,L"\\Device\\TdiFilter");
RtlInitUnicodeString(&FilDevLink,L"\\DosDevices\\TdiFilter");
//Create Device
status = IoCreateDevice(pDriObj,0,NULL,FILE_DEVICE_UNKNOWN,0,TRUE,&g_DevObj);
//Create SymbolicLink
status = IoCreateSymbolicLink(&FilDevLink,&FilDevName);
应用程序：
hFile = CreateFile("\\\\.\\TdiFilter",GENERIC_READ | GENERIC_WRITE,FILE_SHARE_READ | FILE_SHARE_WRITE,NULL,OPEN_EXISTING,0,NULL);
怎么hFIle总是INVALID_HANDLE_VALUE

你在驱动里面要处理CDO的CREATE,CLOSE,CLEANUP函数

DriverEntry
{
  。。。
             DriverObject->MajorFunction[IRP_MJ_CREATE] = FsDeviceCreate;
    DriverObject->MajorFunction[IRP_MJ_CLOSE] = FsDeviceClose;
    DriverObject->MajorFunction[IRP_MJ_CLEANUP] = FsDeviceClose;
}

NTSTATUS
FsDeviceCreate(IN PDEVICE_OBJECT DeviceObject,
               IN PIRP Irp)
{
    PIO_STACK_LOCATION irpStack = IoGetCurrentIrpStackLocation (Irp);
    if (g_CDO == DeviceObject)
    {
        KdPrint(("CDO Created!\n"));
        Irp->IoStatus.Information = 0;
        Irp->IoStatus.Status = STATUS_SUCCESS;
        IoCompleteRequest(Irp, IO_NO_INCREMENT);
        return STATUS_SUCCESS;
    }
    return SfPassThrough(DeviceObject, Irp);
}

NTSTATUS
FsDeviceClose(IN PDEVICE_OBJECT DeviceObject,
              IN PIRP Irp)
{
    if (g_CDO == DeviceObject)
    {
        KdPrint(("CDO Closed!\n"));
        Irp->IoStatus.Information = 0;
        Irp->IoStatus.Status = STATUS_SUCCESS;
        IoCompleteRequest(Irp, IO_NO_INCREMENT);
        return STATUS_SUCCESS;
    }
    return SfPassThrough(DeviceObject, Irp);
}
NTSTATUS
SfPassThrough(IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp)
{
    PIO_STACK_LOCATION irpSp = IoGetCurrentIrpStackLocation(Irp);
    //不处理
    //ASSERT(IS_MY_DEVICE_OBJECT(DeviceObject));
    if (g_CDO == DeviceObject)
    {
        KdPrint((("ERROR CDO:[%08x]\n"), irpSp->MajorFunction, irpSp->MinorFunction));
        //_asm int 3;
        Irp->IoStatus.Status = STATUS_INVALID_DEVICE_REQUEST;
        Irp->IoStatus.Information = 0;
        IoCompleteRequest(Irp, IO_NO_INCREMENT);
        return STATUS_INVALID_DEVICE_REQUEST;
    }
    IoSkipCurrentIrpStackLocation(Irp);
    return IoCallDriver(((PDEVICE_EXTENSION)DeviceObject->DeviceExtension)->AttachedToDevice, Irp);
}

RtlInitUnicodeString(&FilDevLink,L"\\DosDevices\\TdiFilter");这句改成RtlInitUnicodeString(&FilDevLink,L"\\??\\TdiFilter"); 再试试
