How do I get a device's parent in c++ on windows?
Question
我发现SetupDiGetDeviceRegistryProperty从设备获取属性，但我SetupDiGetDeviceRegistryProperty弄明白如何获取父属性（当您在设备管理器中打开设备属性时，可以看到此属性，单击详细信息，然后从属性下拉列表中选择父级。如何从本机c ++代码访问该属性？

The predefined DEVPKEY_Device_Parent guid is the key for the Parent property. Read it with SetupDiGetDeviceInterfaceProperty().
