如何在驱动之间交换数据。
如何在两个WDM间交换大批的数据？

我只知道可以用ZwCreateFile、ZwCloseFile、ZwReadFile、ZwWriteFile等例程与另一驱动交互，不过不知道具体过程。 |

Maybe you can use InternalDeviceIoControl to implement it. I've ever successfully communicate between 2 drivers but never transfer large amount of data.

As you said , Maybe this is a way to exchange data between drivers. Now ,the other way. I want to exchange data between two processes of the same driver copy . Have you used context to exchange data?
Thanks! [lxf 编辑于 2001-04-06 16:47] |

Sorry. I've never done it. In Ring3, we can use file mapping to implement it - I just finished a program with this tech. In Ring0, I don't know if there is a same way to do this.

1. 用IoCreateSymbolicLink为创建驱动程序创建一个符号连接
2. 在需要与之通讯的驱动程序中用IoCreateFile打开这个符号链接 3. 用IoCallDriver实现两个驱动程序之间的通讯 [编辑 - 5/14/02 by archim] |

你可以创建一个命名设备啊！然后在另外的驱动程序里面获得这个设备对象，之后就可以相互通信了啊！
