Function 4411h          Query IOCTL Device                           DOS 5.0+

    Determines whether the specified IOCTL function is supported by
    the given drive.

    ──────────────────────────────────────────────────────────────────
              
    This function returns an error value of 1 (invalid function) if
    the device driver has no support for IOCTL functions, 5 (access
    denied) if the driver supports IOCTL functions but does not
    support the specified IOCTL.
