+    <title>Description</title>
+
+    <para><function>sd_bus_set_close_on_exit()</function> may be used to enable or disable whether
+    the bus connection is automatically flushed (as in
+    <citerefentry><refentrytitle>sd_bus_flush</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
+    and closed (as in
+    <citerefentry><refentrytitle>sd_bus_close</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
+    during the exit phase of the event loop. This logic only applies to bus connections that are
+    attached to an
+    <citerefentry><refentrytitle>sd-event</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    event loop, see
+    <citerefentry><refentrytitle>sd_bus_attach_event</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+    By default this mechanism is enabled and makes sure that any pending messages that have not been
+    written to the bus connection are written out when the event loop is shutting down. In some
+    cases this behaviour is not desirable, for example when the bus connection shall remain usable
+    until after the event loop exited. If <parameter>b</parameter> is true, the feature is enabled
+    (which is the default), otherwise disabled.</para>
+
+    <para><function>sd_bus_get_close_on_exit()</function> may be used to query the current setting
+    of this feature. It returns zero when the feature is disabled, and positive if enabled.</para>
+  </refsect1>
+
+  <refsect1>
+    <title>Return Value</title>
+
+    <para>On success, <function>sd_bus_set_close_on_exit()</function> returns a non-negative
+    integer. On failure, it returns a negative errno-style error code.</para>
+
+    <para><function>sd_bus_get_close_on_exit()</function> returns 0 if the feature is currently
+    disabled or a positive integer if it is enabled. On failure, it returns a negative errno-style
+    error code.</para>
