驅動程序測試問題

為什么我的測試程序測試不成功？

　　測試程序的CreateFile的返回值-1, GetLastError 錯誤碼是123（文件名、目錄名或卷標語法不正確。）

　　我的驅動程序加載后用winObj是可以查看到FirstDevice的，測試程序運行時就是失敗？？？

　　代碼:

　　驅動程序：

#include "ntddk.h"

NTSTATUS CreateDevice(PDRIVER_OBJECT pDriverObject);

NTSTATUS CreateComplateRoutine(PDEVICE_OBJECT pDeviceObj, PIRP pIrp);

NTSTATUS ReadComplateRoutine(PDEVICE_OBJECT pDeviceObj, PIRP pIrp);

NTSTATUS WriteComplateRoutine(PDEVICE_OBJECT pDeviceObj, PIRP pIrp);

NTSTATUS CloseComplateRoutine(PDEVICE_OBJECT pDeviceObj, PIRP pIrp);

VOID MyDriverUnoad(PDRIVER_OBJECT pDriverObject);

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObject,PUNICODE_STRING pRegistryPath)

{

NTSTATUS status;

status = CreateDevice(pDriverObject);

KdPrint(("CreateDevice."));

if (!NT_SUCCESS(status))

{

KdPrint(("Create device faild."));

}

else

{

KdPrint(("Create device success."));

KdPrint(("%wZ", pRegistryPath));

}

pDriverObject->MajorFunction[IRP_MJ_CREATE] = CreateComplateRoutine;

pDriverObject->MajorFunction[IRP_MJ_READ] = ReadComplateRoutine;

pDriverObject->MajorFunction[IRP_MJ_WRITE] = WriteComplateRoutine;

pDriverObject->MajorFunction[IRP_MJ_CLOSE] = CloseComplateRoutine;

pDriverObject->DriverUnload = MyDriverUnoad;

return STATUS_SUCCESS;

}

NTSTATUS CreateDevice(PDRIVER_OBJECT pDriverObject)

{

NTSTATUS status;

PDEVICE_OBJECT pDevObj;

UNICODE_STRING usDevName;

UNICODE_STRING usSymName;

RtlInitUnicodeString(&usDevName, L"\\Device\\FirstDevice");

RtlInitUnicodeString(&usSymName, L"\\??\\FirstDevice");;

status = IoCreateDevice(pDriverObject,

&usDevName,

FILE_DEVICE_UNKNOWN,

TRUE,

&pDevObj);

pDevObj->Flags |= DO_BUFFERED_IO;

if (!NT_SUCCESS(status))

{

KdPrint(("IoCreateDevice faild."));

return status;

}

status = IoCreateSymbolicLink(&usSymName, &usDevName);

if (!NT_SUCCESS(status))

{

KdPrint(("IoCreateSymbolicLink faild."));

IoDeleteDevice(pDevObj);

return status;

}

return STATUS_SUCCESS;

}

NTSTATUS CreateComplateRoutine (PDEVICE_OBJECT pDeviceObj, PIRP pIrp)

{

NTSTATUS status;

status = STATUS_SUCCESS;

KdPrint(("Create"));

pIrp->IoStatus.Status = status;

pIrp->IoStatus.Information = 0;

IoCompleteRequest(pIrp, IO_NO_INCREMENT);

return status;

}

NTSTATUS ReadComplateRoutine (PDEVICE_OBJECT pDeviceObj, PIRP pIrp)

{

NTSTATUS status;

status = STATUS_SUCCESS;

return status;

}

NTSTATUS WriteComplateRoutine (PDEVICE_OBJECT pDeviceObj, PIRP pIrp)

{

NTSTATUS status;

status = STATUS_SUCCESS;

return status;

}

NTSTATUS CloseComplateRoutine (PDEVICE_OBJECT pDeviceObj, PIRP pIrp)

{

NTSTATUS status;

status = STATUS_SUCCESS;

return status;

}

VOID MyDriverUnoad(PDRIVER_OBJECT pDriverObject)

{

UNICODE_STRING usSymName;

RtlInitUnicodeString(&usSymName, L"\\??\\FirstDevice");

if (pDriverObject->DeviceObject != NULL)

{

IoDeleteSymbolicLink(&usSymName);

IoDeleteDevice(pDriverObject->DeviceObject);

KdPrint(("Delete device success!"));

}

　測試程序：

　　代碼:

void CTestMyFirstDriverDlg::OnBnClickedButton1()

{

// TODO: Add your control notification handler code here

HANDLE hFile = CreateFile(L"\\??\\FirstDevice",

FILE_ALL_ACCESS,

FILE_SHARE_READ,

NULL,

OPEN_EXISTING,

FILE_ATTRIBUTE_NORMAL,NULL);

if (hFile == INVALID_HANDLE_VALUE)

{

int err = GetLastError();

MessageBox(L"Create File error!");

}

CloseHandle(hFile);

return;

}
