0x18 PnP IRP???

NTDEV
1

Hi all,

When I debug my WDM bus driver for a vertual device in Win 2k, the driver
received 0x18 PnP IRP which does not exist or is not documented in MSND. How
can I handle it?

Thanks

James

Is 0x18 the value of Major Funciton Code?

If it is, look at the the following line that
defined in ntddk.h

#define IRP_MJ_DEVICE_CHANGE 0x18

#define IRP_MN_SURPRISE_REMOVAL 0x17
// end_wdm
#define IRP_MN_QUERY_LEGACY_BUS_INFORMATION 0x18
// begin_wdm

from ntddk.h.

No, it’s minor function. The major is IRP_MJ_PNP (0x1b).

Thanks

If you see it under IRP_MJ_PNP how can it be a major code?

<< Is 0x18 the value of Major Funciton Code?

If it is, look at the the following line that
defined in ntddk.h

#define IRP_MJ_DEVICE_CHANGE 0x18 >>

The major function is IRP_MJ_PNP (0x1b) and the minor function is 0x18.

So Dinker, do you know normally how to handle this function? My device is a
USB device. Currently, I don’t handle it.

Another question: How to add my own driver symbols to WinDbg in Win2000?
Right now, I have a symbols directory and a sub directory sys for my driver
and copied *.pdb (I also tried *.sys, *.sym) to the sub directory and in
WinDbg setting, I set the directory path. But when my driver is loaded,
WinDbg still can not find the symbol. Waht’s wrong?

Thanks

James

In your runwdeb.wrf file add the following:
/s:C:\SymDir\MySymFile.Sym

That’s how Win9x WDEB386 works. I believe WinDbg should require the same
semantics.

You must have all .sys .pdb .dbg files in this directory. Maybe this will
help - at
least it helped me with windbg build 1999.

How to create *.dbg? DDK ony creates *.sys and *.pdb. Also, I don’t see in
DDK doc that *.dbg are needed.

Thanks

One of the KB articles listed on
http://www.microsoft.com/hwdev/driver/ntdebugging.htm has information on
.dbg and .pdb files.

Also take a look at the new documentation with excellent advanced debugging
tips on Microsoft debuggers.

> How to create *.dbg? DDK ony creates *.sys and *.pdb. Also, I don’t see in

Depends on SOURCES file settings & compiler version (MSVC5 or 6).
Yes, for one of the modes you will get .sys .pdb. For others - .sys .dbg
I don’t think there is a mode when you will get all three of them.

The REBASE utility (part of the SDK) has a switch that will create .DBG
files. I seem to recall having to compile code with the /Z7 switch and
linking with the /PDB:none in order to get debug symbols bound into an
executable, and not broken off into a seperate PDB file.
