They come back with put “##000” in the subject. Who knows and I’m caring
less now.

That should work, what happened when you tried it?

Hi,
I took a look at your article. I find it very useful. Now I am changing my
code to use LIST_ENTRY.
typedef struct _MY_DATA {
LIST_ENTRY ListEntry;
ULONG Data;
ULONG Data2;
LIST_ENTRY ListEntry;
} MY_DATA, *PMY_DATA;
I have a question:
0:000> !list “-t _LIST_ENTRY.Flink -x "? @@(#CONTAINING_RECORD(@$extret,
_MY_DATA, ListEntry));dt _MY_DATA @@(#CONTAINING_RECORD(@$extret, _MY_DATA,
ListEntry))" @@(head.Flink)”
Now if I want to print only a few elements in MY_DATA structure and not
entire structure , say want to print just Data, Data2 members,
will modifying the above as:
0:000> !list “-t _LIST_ENTRY.Flink -x "? @@(#CONTAINING_RECORD(@$extret,
_MY_DATA, ListEntry));dt _MY_DATA @@(#CONTAINING_RECORD(@$extret, _MY_DATA,
ListEntry)) Data Data2" @@(head.Flink)”
work?
Note Data and Data2 added towards the end of the command.
Regards,
-Praveen

The answer to this seems pretty obvious. If you write your own custom
data structure, then you will surely need your own custom windbg
extension to traverse it.
That’s one darned good reason to use LIST_ENTRY instead of rolling your
own.
One of my favorite features of the GNU gdb debugger is that you can call
named routines in the module under test. I often include debug
functions that are never called in the code, specifically for use within
gdb. It’s a lot easier than writing a formal debugger extension.
