IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS IOCTL

Retrieves the physical location of a specified volume on one or more disks.

To perform this operation, call the DeviceIoControl function with the following parameters.

C++
BOOL 
WINAPI 
DeviceIoControl( (HANDLE) hDevice,                     // handle to device
                 IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS, // dwIoControlCodeNULL,                                 // lpInBuffer0,                                    // nInBufferSize(LPVOID) lpOutBuffer,                 // output buffer
                 (DWORD) nOutBufferSize,               // size of output buffer
                 (LPDWORD) lpBytesReturned,            // number of bytes returned
                 (LPOVERLAPPED) lpOverlapped           // OVERLAPPED structure
);
