我编写了一个示例 KMDF 驱动程序。我不知道我是否做对了所有事情，但在 DebugView 实用程序中看到 KMDF 驱动程序打印调试消息 - 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“示例设备”。

现在我想编写一个可以调用这个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 INF 文件如下所示：-

WDK 中有很多相关的示例。例如，看看KMDF Echo 示例。

首先，您需要命名您的对象。其次，您至少需要执行以下操作之一：

  1. 在 \GLOBAL??\ 中创建符号链接
  2. 注册设备接口。

选项 1 将让您做简单的事

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

选项 2，您将需要使用 Setup DI Api 例程来找到您的设备以将其打开。
