+    <title>Description</title>
+
+    <para><function>sd_event_source_set_exit_on_failure()</function> may be used to set/unset the
+    exit-on-failure flag of the event source object specified as <parameter>source</parameter>. The flag
+    defaults to off. If on and the callback function set for the event source returns a failure code (i.e. a
+    negative value) the event loop is exited too, using the callback return code as the exit code for
+    <citerefentry><refentrytitle>sd_event_exit</refentrytitle><manvolnum>3</manvolnum></citerefentry>. If
+    off, the event source is disabled but the event loop continues to run. Setting this flag is useful for
+    "dominant" event sources that define the purpose and reason for the event loop, and whose failure hence
+    should propagate to the event loop itself — as opposed to "auxiliary" event sources whose failures should
+    remain local and affect the event source, but not propagate further.</para>
+
+    <para><function>sd_event_source_get_exit_on_failure()</function> may be used to query the flag currently
+    set for the event source object <parameter>source</parameter>.</para>

+    <title>Return Value</title>
+
+    <para>On success, <function>sd_event_source_set_exit_on_failure()</function> returns a non-negative
+    integer.  <function>sd_event_source_get_exit_on_failure()</function> returns 0 if the flag is off, &gt; 0
+    if the flag is on. On failure, both return a negative errno-style error code.</para>
