gdb in emacs : dereference pointer

I know this sounds ridiculous but I cant figure out how to
get emacs to
display VALUES or dereferenced values in the locals or any
other pane of the
multi-window GUD setup.

Yes, I can "display" so it is shown after every
step but that is horrible -
I want it in a fixed place in the locals pane. What obvious
thing am I
missing here?

I really dont want to use ddd.

It does sound a bit ridiculous because this is mailing for
GDB not Emacs

You can't currently do this as it's not straightforward to
implement.  You can
dereference them as watch expressions in the speedbar (maybe
thats what you
mean by "display").

Insight does what you want.

There is a strong tie in : and its more gdb related than
emacs
related. I would have expected a lot of gdb users to run it
from within
emacs. Sorry if you consider it OT.

I try not to use the speedbar : I find it buggy and
unresponsive.

Thanks. I will take a look.

Its just that your question is about functionality in CVS
Emacs.  There may be
many people on this list who don't even use Emacs.

You need at least GDB 6.0 for it to work, but it works much
better with 6.4 or
later.  If you still have problems then please report them
to
emacs-pretest-buggnu.org.  Thats the only way we can
improve it.

Whoa.  I think questions like this deserve a gentler
response.  This
isn't a gdb-developers or gdb-experts list; it's the GDB
list.

If one is not familiar with the whole architecture, then
when running
GDB under Emacs it can be unclear which component you need
to talk to
to get something done.  (Having just tried Eclipse for the
first time
last night, this point is very fresh in my mind.)

It's just a link to what was said before, and was followed
up with constructive
comments.  Often I would prefer such a reply to none at all
where I am just
left in a state of ignorance.
