Dear all,

There are many OIDs defined in header file Windot11.h.
I tried to create new OID which is only used for our product and used
DeviceIoControl to Set/Query some data to/from driver. But I got error
code number 87 (The parameter is incorrect.). Who can tell me how to
reslove it or have any ideas? Thanks a lot..

You can create your custom OIDs but the first byte must be 0xFF.

Hi Stephan,

I have tried to use the method you mentioned. But the result was same
as previous result.
Do you have sample code or other suggestions? Thanks.

Thanks, Stephan

I assume he solved it by not calling an OID via DeviceIoControl().

Hi Stephan,

Just as you said. The custom OIDs should be started with 0xFF.

For example,
#define EX_OID_DOT11_EXAMPLE 0xFF000001.

NDIS_OID SupportedOIDs[] = {EX_OID_DOT11_EXAMPLE,... }

....an Query OID interface...
{
switch(oid)
{
case OID_GEN_SUPPORTED_LIST:
pInfo = (PVOID) SupportedOids;
ulInfoLen = sizeof(SupportedOids);
break;
case ...
case....
}
}

Don't forget to set an array filled OIDs and use OID_GEN_SUPPORTED_LIST
to indicate the array to NDIS. The array is used to tell NDIS how many
supported OIDs to filter.
Now we can set/query an action of OID from application layer.

In fact, I still used DeviceIoControl to implement in application
layer.

So you have a protocol driver that takes the OID value out of an IOLCTL
and passes it to your Nic driver.
