Question

我已经编写了一个示例KMDF驱动程序。我不知道我是否做了所有事情，但已经看到KMDF驱动程序在DebugView实用程序中打印调试消息 - 当我将此驱动程序添加为新硬件时。它还在设备管理器下显示为“Sample Device”。

现在我想编写一个可以调用此驱动程序的示例客户端 - 这样我就可以在驱动程序和客户端之间建立连接。我读到我们需要使用'CreateFile'和'DEviceIOControl'等。但是我无法开始使用它。

您能否指导我创建示例客户端以访问示例KMDF驱动程序？

我的驱动程序的INF文件如下所示： -

Answer 1

WDK中有许多相关样本。例如，请查看KMDF Echo sample。

Answer 2

首先，您需要为对象命名。其次，您需要至少执行以下一项操作：

在\ GLOBAL ?? \
注册设备接口。

选项1可以让你做简单的

CreateFile("\\\\.\\<device_name>, ...);

选项2，您需要使用Setup DI Api例程找到要打开它的设备。
