二、驱动

二、驱动

2.1.hello world

1.创建项目

2.删除Driver Files里面的helloworld.inf文件

3.右键属性

Inf2Cat->General->Run Inf2Cat 改成否
Driver Settings->General->Traget OS VERSION和Target Platform改成对一个的平台
C/C++ -->常规->警告等级改为3，将警告视为错误改成否
C/C++ -->代码生成-->Spectre Mitigation改为Disabled

4.helloworld.c

#include <ntifs.h>

VOID DriverUnload(PDRIVER_OBJECT pDriverObject)
{
	DbgPrint("卸载驱动\r\n");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriver, PUNICODE_STRING pReg)
{
	pDriver->DriverUnload = DriverUnload;
	DbgPrint("加载驱动\r\n");
	DbgPrint("注册表路劲：%wZ\r\n",pReg);

	return STATUS_SUCCESS;
}

2.2.驱动基础

1.字符串函数

1.RtiInitString初始化多字节ascii
2.RtiInitUnicodestring初始化宽字符
3.RtlFreeUnicodeString释放uncode字符串
4.RtlStringCbPrintfA格式化输出记得引用#include <ntstrsafe.h
5.RtiCoipareunicodestring字特串比较

2.申请内存

ExAllocatePool   #申请内存
ExFreePool		 #释放内存

3.创建线程

PsCreateSystemThread    #创建线程

2.3.链表

LIST_ENTRY

typedef struct _LIST_ENTRY {
   struct _LIST_ENTRY *Flink;
   struct _LIST_ENTRY *Blink;
} LIST_ENTRY, *PLIST_ENTRY, *RESTRICTED_POINTER PRLIST_ENTRY;

节点

 struct MYNODE{
	LIST_ENTRY ListEntry;
	int data;
 };

操作

InitializeListHead  初始化链表头 
IsListEmpty			判断链表是否为空 
InsertHeadList		从链表头部插入节点 
InsertTailList		从链表尾部插入节点 
RemoveHeadList		从链表头部删除节点 
RemoveTailList		从链表尾部删除节点
