内核模式 文件操作

首先   当编译驱动时发生错误：

LINK : warning LNK4044: unrecognized option '/pdbtype:sept'; ignored
Creating browse info file...
BSCMAKE: error BK1510 : corrupt .SBR file '.sysDriverMemory.sbr'

解决方法：

勾掉工程or项目（各版本翻译不一样）-> 设置or属性（仍然是翻译不一样）-> C/C++ -> 产生浏览信息，编译没有错误了

文件创建：

#pragma INITCODE
VOID MyCreaFile()
{
	OBJECT_ATTRIBUTES obj_attr;
	UNICODE_STRING Obj_Attr_Name;
	IO_STATUS_BLOCK iostatus;
	HANDLE hFile;
	RtlInitUnicodeString(&Obj_Attr_Name,L"\??\C:\1.log");//或者写成 \Device\HarddiskVolume1\1.log

	InitializeObjectAttributes(&obj_attr,&Obj_Attr_Name,OBJ_CASE_INSENSITIVE,NULL,NULL);

	NTSTATUS status = ZwCreateFile(&hFile,
		GENERIC_WRITE,
		&obj_attr,
		&iostatus,
		0,FILE_ATTRIBUTE_NORMAL
		,FILE_SHARE_READ
		,FILE_OPEN_IF,
		FILE_SYNCHRONOUS_IO_NONALERT,
		NULL,0);
	if (!NT_SUCCESS(status))
	{
		KdPrint(("创建文件失败!
"));
	}
	else
	{
		KdPrint(("创建文件成功!
"));
	}
	//文件操作
	ZwClose(hFile);
}

文件打开  两个方式：

#pragma INITCODE
VOID MyOpenFile()
{
	OBJECT_ATTRIBUTES obj_attr1,obj_attr2;
	UNICODE_STRING obj_attr_name1,obj_attr_name2;
	HANDLE  hFile1,hFile2;
	IO_STATUS_BLOCK iostatus1,iostatus2;

	RtlInitUnicodeString(&obj_attr_name1,L"\??\C:\1.log");
	RtlInitUnicodeString(&obj_attr_name2,L"\??\C:\2.log");//不能同时打开同一文件
	InitializeObjectAttributes(&obj_attr1,
		&obj_attr_name1,
		OBJ_CASE_INSENSITIVE,
		NULL,NULL);
	InitializeObjectAttributes(&obj_attr2,
		&obj_attr_name2,
		OBJ_CASE_INSENSITIVE,
		NULL,NULL);
//////////////////////////////////////////////////////////////////////////////方式1
	NTSTATUS status1 = ZwCreateFile(&hFile1,
		FILE_GENERIC_READ,
		&obj_attr1,
		&iostatus1,
		NULL,
		FILE_ATTRIBUTE_NORMAL,
		FILE_SHARE_READ,
		FILE_OPEN,//打开文件，不存在 反悔错误
		FILE_SYNCHRONOUS_IO_NONALERT,
		NULL,0);
//////////////////////////////////////////////////////////////////////////////方式2
	NTSTATUS status2 = ZwOpenFile(&hFile2,
		GENERIC_ALL,
		&obj_attr2,
		&iostatus2,
		FILE_SHARE_READ | FILE_SHARE_WRITE,
		FILE_SYNCHRONOUS_IO_NONALERT);
	if (!NT_SUCCESS(status1))
	{
		KdPrint(("方式1：打开文件失败"));
	}
	else
	{
		KdPrint(("方式1：打开文件成功"));
	}
	if (!NT_SUCCESS(status2))
	{
		KdPrint(("方式2：打开文件失败"));
	}
	else
	{
		KdPrint(("方式2：打开文件成功"));
	}
	ZwClose(hFile1);
	ZwClose(hFile2);
}

实验    修改文件属性：

#pragma INITCODE
VOID MyQueryInformationFile()
{
	HANDLE hFile;
	OBJECT_ATTRIBUTES obj_attr;
	UNICODE_STRING obj_attr_name;
	IO_STATUS_BLOCK io_status;

	RtlInitUnicodeString(&obj_attr_name,L"\??\C:\my.log");
	InitializeObjectAttributes(&obj_attr,
		&obj_attr_name,
		OBJ_CASE_INSENSITIVE,
		NULL,NULL);


	NTSTATUS status = ZwCreateFile(&hFile,
		GENERIC_READ,
		&obj_attr,
		&io_status,
		0,
		FILE_ATTRIBUTE_NORMAL,
		0,
		FILE_OPEN,//文件不存在  报错
		FILE_SYNCHRONOUS_IO_NONALERT,
		NULL,0
		);
		if (!NT_SUCCESS(status))
		{
			KdPrint(("文件创建失败

		}
		else
			KdPrint(("文件创建成功

//////////////////////////////////////////////////////////////////////////////////获取文件信息

		{
			KdPrint(("文件获取信息失败

			KdPrint(("file length: %u

///////////////////////////////////////////////////////////////////////////////////修改文件指针

		FILE_POSITION_INFORMATION fpi;

			}	
					KdPrint(("修改信息：

					fbi.ChangeTime.QuadPart = 100i64;
					fbi.CreationTime.QuadPart = 100i64;

					fbi.LastAccessTime.QuadPart = 100i64;
					fbi.LastWriteTime.QuadPart = 100i64;
			status = ZwSetInformationFile(hFile,&io_status,

					ZwClose(hFile);
