如何从网络逻辑磁盘名称获取物理磁盘索引？

Question

I'm writing a program which will be able to show hdd disk performance. Input data for the program is logical disk name("D:","E:"etc.). I have to get physical disk index from logical disk name. There are no problem for local machine. I can do this like:

 HANDLE h = ::CreateFile( L"\\\\.\\d:" , 0 , 0 , NULL , OPEN_EXISTING, 0 , NULL);  
  STORAGE_DEVICE_NUMBER info = { };   
   DWORD bytesReturned = 0;
   ::DeviceIoControl( h , IOCTL_STORAGE_GET_DEVICE_NUMBER , NULL , 0,&info,sizeof( info ) , &bytesReturned , NULL );

then use info.DeviceNumber for further usage. But i don't know how to do the same for network drive. How can I change local path L"\\\\\\\\.\\\\D:" if i need get handle of network logic drive "D:" at server named "server1" . I have tried L"\\\\\\\\server1\\\\\\\\.\\\\D:" , L"server1\\\\\\\\.\\\\D:" etc. but it hasn't helped.

Answer 1

You can't. There's no support in the network protocol to request that sort of information. server1 might not even have the notion of a "physical disk index".
