将Windows驱动程序连接到Userland服务 [英] Connecting Windows Driver to Userland Service

问题描述

如何与Windows中的用户区的驱动程序进行通信？ （如果有，Vista会有所不同。）我可以以及如何通过驱动程序站点与服务进行通信？

How do I communicate with a driver from the userland in Windows? (Vista if that makes a difference.) Can I, and how, communicate with the service from the driver site?

我实际上不是很懒惰，应该让老板给我买书，但是我不知道是哪本书。在没有正确的术语搜索的情况下，从MSDN猜测命令和部分会花费很多时间和精力。有人可以给我一些术语以在文档中寻找吗？

I am actually not very lazy and should probably get my boss to buy me a book, but I don't know which. And guessing commands and sections from the MSDN is kinda taking a lot of nerves and time without the right terms to search for. Can someone drop me some terms to look for in the documentation?

推荐答案

在线OSR 是编写Windows驱动程序的良好信息。

OSR online is a good source of information on writing windows drivers.

如何以内核模式命名设备（带有访问安全性的链接）。

How to name devices in kernel mode (with a link to access security).

基本路径是：

使用一种命名功能（例如WdfDeviceInitAssignName）命名设备对象。

Name your device object with one of the naming functions (e.g. WdfDeviceInitAssignName).

在服务中您可以执行以下操作：

In the service you do :

hDev = CreateFile( <obj name>, ..., OVERLAPPED )

DeviceIOControl( hDev, .. , OVERLAPPED);

while( !end )
   SleepEx( 100, true /*bAltertable*/ );

...

在驱动程序中，您有一个IRP队列，在其中将来自服务的请求排队。当您要调用该服务时，您需要完成一个IRP。

In the driver, you have an IRP queue, in which you queue requests from the service. When you want to call the service, you complete one of the IRPs.

NB：这有点复杂...并且取决于您使用的驱动程序框架/模型用。我只需要在NDIS过滤器驱动程序中执行一次。再问一次，是否需要更多信息。

NB: Its a bit complex ... and depends on the driver framework/model you are working with. I had to do this only once with in a NDIS filter driver. Ask again, if you need more info.
