I am assuming that all the regular atexit handlers have already been called, and that Emacs is really about to exit. (That is what I mean by saying that kill-emacs has been run.) So, this could be implemented by ensuring that the first atexit handler to be registered on startup checks a "kill-emacs-and-exec" flag, and if it is set, does the exec. Correspondingly, kill-emacs-and-exec would set the flag, store the arguments in a suitable place, and then tail-call to kill-emacs. -- http://rrt.sc3d.org --20cf3011dc83bdfdf504f51b1364 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable

As long as it does what you want, fine. =A0But please note that this = is
not the same as exiting Emacs and starting a new session, because the
original Emacs didn't shut down all the way, and the PID is the same.

I think I'm sti= ll being unclear, sorry.

I am assum= ing that all the regular atexit handlers have already been called, and that= Emacs is really about to exit. (That is what I mean by saying that kill-em= acs has been run.) So, this could be implemented by ensuring that the first= atexit handler to be registered on startup checks a "kill-emacs-and-e= xec" flag, and if it is set, does the exec. Correspondingly, kill-emac= s-and-exec would set the flag, store the arguments in a suitable place, and= then tail-call to kill-emacs.
