我从
获取USB设备路径SetupDiGetDeviceInterfaceDetail()
我可以得到像这样的设备路径
\\?\usbstor#disk&ven_&prod_2307_pram&......
但我想将设备路径映射到物理Drvie
-> \\physicaldrive0,1,2......
或反之,我可以将物理Drvie映射到设备路径
有什么办法吗?
答案 0 :(得分:0)
哦,我找到了。 将HANDLE放入DeviceIoControl并使用IOCTL_STORAGE_GET_DEVICE_NUMBER
STORAGE_DEVICE_NUMBER number; //use this to get disk numbers
DWORD readed; // discard results
BOOL result = DeviceIoControl(
hdl, // handle to device
IOCTL_STORAGE_GET_DEVICE_NUMBER, // dwIoControlCode
NULL, // lpInBuffer
0, // nInBufferSize
&number, // output buffer
sizeof(number), // size of output buffer
&readed, // number of bytes returned
NULL // OVERLAPPED structure
);
和数字。DeviceNumber是PhysicalDrive编号
