谁能解释一下 IoGetDeviceObjectPointer
DDK上说：“。。。establishes a \"connection\" between the caller and the next-lower-level driver。。。”
不明白，这函数有什么用 |

IoGetDeviceObjectPointer establishes a \"connection\" between the caller and the next-lower-level driver. A successful caller can use the returned device object pointer to initialize its own device object(s). It can also be used as as an argument to IoAttachDeviceToDeviceStack,
你可以用他来获得目标设备对象指针，然后利用IoAttachDeviceToDeviceStack，加到该对象上，从而成为目标设备对象的过滤器。。。。。。 |
