For subprocesses that run a program, it sends them the <code>SIGHUP</code> signal; connections are simply closed. 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-<code>nil</code>, says that Emacs should ask for confirmation before exiting and thus killing that process. The default for the query flag is <code>t</code>, meaning <em>do</em> query. </p> <dl> <dt id="process-query-on-exit-flag">Function: <strong>process-query-on-exit-flag</strong> <em>process</em> +</dt> <dd><p>This returns the query flag of <var>process</var>. </p></dd> +</dl> <dl> <dt id="set-process-query-on-exit-flag">Function: <strong>set-process-query-on-exit-flag</strong> <em>process flag</em> +</dt> <dd> +<p>This function sets the query flag of <var>process</var> to <var>flag</var>.
