server emacs - how to get file/line/col of previous buffer?

[Michal]

Hallo Group members!
I added following functions to server*-hook:

(add-hook 'server-switch-hook
          (function (lambda () 
                      (message "%s: server-switch-hook" (buffer-name)))))

(add-hook 'server-visit-hook
          (function (lambda () 
                      (message "%s: server-visit-hook" (buffer-name)))))


then,

M-x server-start

then from outside emacs:

$ emacsclient --no-wait /tmp/p1.c


emacs produces following message:

p1.c: server-visit-hook
p1.c: server-switch-hook


... but, Have You got idea on how to get info about buffer we jumped from?

Regards,
Michal
