IoGetDeviceObjectPointer 获取对象失败，没有权限。

、

IRP_MJ_READ的派遣函数中调用该函数总是失败，返回代码是：#define STATUS_ACCESS_DENIED ((NTSTATUS)0xC0000022L)

换了个方法：ObreferecnByName 返回的代码呢是： #define STATUS_OBJECT_TYPE_MISMATCH ((NTSTATUS)0xC0000024L)

然而在初始化创建驱动设备的时候是可以的：



以下是所有代码：

引用 3 楼 Huntercao 的回复:
在OperatoeDevice中，IoGetDeviceObjectPointer函数的第二个参数设置成FILE_READ_DATA看看。 不要用FILE_ALL_ACCESS。
谢谢，我后来改了声明，在未归档函数 “ObReferenceObjectByName”的第5个参数？ 就设备类型那个： PIO_OBJECT_TYPE IoDeviceObjectType修改为 PIO_OBJECT_TYPE *IoDeviceObjectType二级指针 传参的时候 *DeviceObject即可， 一个一级指针，一个二级指针。。。但是二级指针还是解引用成了一级指针，这是因为声明错误导致的调用错误码？ 这样传参不一样的吗？ 我很纳闷，
