SD serial number

Question

I am using the following code:

int main()
{


    DWORD dwBytesReturned = 0;
    BOOL bResult = DeviceIoControl(hVol, IOCTL_SFFDISK_DEVICE_COMMAND, pCmdBuf, nSizeOfCmd, pCmdBuf, nSizeOfCmd, &dwBytesReturned, NULL);

But pCmdBuf->Data is always empty. I run the program with administrative privileges on a win7 x64.

Answer 1
