Next: Suspending Emacs, Up: Getting Out
Killing Emacs means ending the execution of the Emacs process. The
parent process normally resumes control. The low-level primitive for
killing Emacs is kill-emacs
.
This function exits the Emacs process and kills it.
If exit-data is an integer, then it is used as the exit status of the Emacs process. (This is useful primarily in batch operation; see Batch Mode.)
If exit-data is a string, its contents are stuffed into the terminal input buffer so that the shell (or whatever program next reads input) can read them.
All the information in the Emacs process, aside from files that have
been saved, is lost when the Emacs process is killed. Because killing
Emacs inadvertently can lose a lot of work, Emacs queries for
confirmation before actually terminating if you have buffers that need
saving or subprocesses that are running. This is done in the function
save-buffers-kill-emacs
.
After asking the standard questions,
save-buffers-kill-emacs
calls the functions in the listkill-emacs-query-functions
, in order of appearance, with no arguments. These functions can ask for additional confirmation from the user. If any of them returnsnil
, Emacs is not killed.
