IRP_MJ_READ 项目 2023/06/15 2 个参与者 反馈 本文内容 发送时间 输入参数 输出参数 Operation 显示另外 2 个 将数据从其设备传输到系统的每个设备驱动程序都必须处理 DispatchRead 或DispatchReadWrite 例程中的读取请求,与在此类设备驱动程序上分层的任何更高级别的驱动程序一样。
某些类型的驱动程序还使用Parameters.Read.ByteOffset中的值,该值指示传输操作的起始偏移量。 有关示例,请参阅可安装文件系统(IFS) 文档中的 IRP_MJ_READ 主题。 输出参数 根据基础设备驱动程序是使用DO_BUFFERED_IO还是DO_DIRECT_IO设置目标设备对象的标志,数据将传输到以下其中一个: ...

这两天学写驱动以下是我的com.sys的代码...可以捕捉到读与写的数据并在dbg中显示出来并且dbg里显示的都是我修改过的数据...也就是说成功了...但是串口调试工具与监听工具查的话只有IRP_MJ_WRITE的数据可以修改成功IRP_MJ_READ的数据依然没有改变... 请问应该怎么修改才可以改变从设备传回来的IRP_MJ_READ数据...

I’ve tried to read file data in IRP_MJ_READ dispatch routine and display the file content. I’m trying to use Direct I/O for file read/write. However, the code can’t work. Would you please point out what are wrong ? What I’ve got are a number of meaningless bytes. ...
