@vindex kill-buffer-query-functions
You can program additional requests for confirmation. After confirming
unsaved changes, @code{kill-buffer} calls the functions in the list
@code{kill-buffer-query-functions}, in order of appearance, with no
arguments. The buffer being killed is the current buffer when they are
called. The idea is that these functions ask for confirmation from the
user for various nonstandard reasons. If any of them returns
non-@code{nil}, the buffer is not killed.
@c Emacs 19 feature
@vindex kill-buffer-hook
Just before actually killing the buffer, after asking all questions,
@code{kill-buffer} runs the normal hook @code{kill-buffer-hook}. The
buffer to be killed is current when the hook functions run.

Killing a buffer that is already dead has no effect.

in the list @code{kill-buffer-query-functions}, in order of appearance,

@defvar buffer-offer-save
This variable, if non-@code{nil} in a particular buffer, tells
@code{save-buffers-kill-emacs} and @code{save-some-buffers} to offer to
save that buffer, just as they offer to save file-visiting buffers. The
variable @code{buffer-offer-save} automatically becomes buffer-local
when set for any reason. @xref{Buffer-Local Variables}.
