DeviceIoControl问题

DeviceIoControl问题


驱动：
RtlInitUnicodeString(&FilDevName,L"\\Device\\TdiFilter");
RtlInitUnicodeString(&FilDevLink,L"\\DosDevices\\TdiFilter");
//Create Device
status = IoCreateDevice(pDriObj,0,NULL,FILE_DEVICE_UNKNOWN,0,TRUE,&g_DevObj);
//Create SymbolicLink
status = IoCreateSymbolicLink(&FilDevLink,&FilDevName);
应用程序：
hFile = CreateFile("\\\\.\\TdiFilter",GENERIC_READ | GENERIC_WRITE,FILE_SHARE_READ | FILE_SHARE_WRITE,NULL,OPEN_EXISTING,0,NULL);
怎么hFIle总是INVALID_HANDLE_VALUE

确认驱动装上了吗？
