37.11 Querying Before Exit

When Emacs exits, it terminates all its subprocesses by sending them the SIGHUP signal. Because subprocesses may be doing valuable work, Emacs normally asks the user to confirm that it is ok to terminate them. Each process has a query flag which, if non-nil, says that Emacs should ask for confirmation before exiting and thus killing that process. The default for the query flag is t, meaning do query.

Function: process-query-on-exit-flag process

This returns the query flag of process.

Function: set-process-query-on-exit-flag process flag

This function sets the query flag of process to flag. It returns flag.

;; Don't query about the shell process (set-process-query-on-exit-flag (get-process "shell") nil) ⇒ t

Function: process-kill-without-query process &optional do-query

This function clears the query flag of process, so that Emacs will not query the user on account of that process.

Actually, the function does more than that: it returns the old value of the process's query flag, and sets the query flag to do-query. Please don't use this function to do those things any more—please use the newer, cleaner functions process-query-on-exit-flag and set-process-query-on-exit-flag in all but the simplest cases. The only way you should use process-kill-without-query nowadays is like this:

;; Don't query about the shell process (process-kill-without-query (get-process "shell"))
