为何 IoReportTargetDeviceChangeAsynchronous 总是蓝屏?

我在驱动中调用 IoReportTargetDeviceChangeAsynchronous 向用户层发送 GUID_TARGET_DEVICE_REMOVE_COMPLETE, 广播设备移除通知, 让应用程序窗口收到 WM_DEVICECHANGE 消息,  但是总是会蓝屏.  网上关于 IoReportTargetDeviceChangeAsynchronous  的信息很少, 抓狂了,有高人能为小弟解惑吗?


TARGET_DEVICE_CUSTOM_NOTIFICATION notify;

notify.Version                   = 1;  
notify.Size                         = sizeof( TARGET_DEVICE_CUSTOM_NOTIFICATION ) + sizeof( ULONG ) - sizeof( UCHAR );  
notify.FileObject               = NULL;  
notify.NameBufferOffset = -1;  

RtlCopyMemory( & notify.Event, & GUID_TARGET_DEVICE_REMOVE_COMPLETE, sizeof( GUID ));
*(( PULONG )( &( notify.CustomDataBuffer[0] ))) = 0;

IoReportTargetDeviceChangeAsynchronous( DeviceObject,  & notify,  NULL,  NULL );

// ... 蓝屏

看来大牛们都忙着春耕去了
