regarding NDISUIO control codes

hi all,
i am facing a problem wrt NDISUIO protocol available alongwith XPDDK.
These are the defnitions defined in nuiouser.h

****************************************************************************
****
define FSCTL_NDISUIO_BASE FILE_DEVICE_NETWORK

#define _NDISUIO_CTL_CODE(_Function, _Method, _Access) \
CTL_CODE(FSCTL_NDISUIO_BASE, _Function, _Method, _Access)

#define IOCTL_NDISUIO_OPEN_DEVICE \
_NDISUIO_CTL_CODE(0x200, METHOD_BUFFERED, FILE_ANY_ACCESS)

#define IOCTL_NDISUIO_QUERY_OID_VALUE \
_NDISUIO_CTL_CODE(0x201, METHOD_BUFFERED, FILE_ANY_ACCESS)

#define IOCTL_NDISUIO_SET_OID_VALUE \
_NDISUIO_CTL_CODE(0x205, METHOD_BUFFERED, FILE_ANY_ACCESS)

#define IOCTL_NDISUIO_SET_ETHER_TYPE \
_NDISUIO_CTL_CODE(0x202, METHOD_BUFFERED, FILE_ANY_ACCESS)

#define IOCTL_NDISUIO_QUERY_BINDING \
_NDISUIO_CTL_CODE(0x203, METHOD_BUFFERED, FILE_ANY_ACCESS)

#define IOCTL_NDISUIO_BIND_WAIT \
_NDISUIO_CTL_CODE(0x204, METHOD_BUFFERED, FILE_ANY_ACCESS)

****************************************************************************
********

now my problem is that in _NDISUIO_CTL_CODE(0x200, METHOD_BUFFERED,
FILE_ANY_ACCESS)
where does this Function value 0x200 coming from ,
and also i want to define my own IOCTL code for Closing the device , what
should be the code.
...where do all these function hexadecimalk values coming from

TIA

Microsoft assigned it. See "Defining I/O Control Codes" in the DDK help.

A value of 0x800 or greater for the Function value.

They are either assigned by MS or you.

Be aware that the IOCTLs for NDISUIO changed between XP RTM and XP SP1 from
ANY_ACCESS to (READ | WRITE); however, you should not be using the in-box
NDISUIO and should be building your own driver based on the NDISUIO sample.

Thanks a lot Marc.

Are these standard IO Control Codes Documented ?
