+
+    <para><function>sd_event_source_set_description()</function> may
+    be used to set an arbitrary descriptive name for the event source
+    object specified as <parameter>source</parameter>. This name will
+    be used in debugging messages generated by
+    <citerefentry><refentrytitle>sd-event</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    for this event source, and may be queried using
+    <function>sd_event_source_get_description()</function> for
+    debugging purposes. The <parameter>description</parameter> parameter shall
+    point to a <constant>NUL</constant>-terminated string or be
+    <constant>NULL</constant>. In the latter case, the descriptive
+    name will be unset. The string is copied internally, hence the
+    <parameter>description</parameter> argument is not referenced
+    after the function returns.</para>
+
+    <para><function>sd_event_source_get_description()</function> may
+    be used to query the current descriptive name assigned to the
+    event source object <parameter>source</parameter>. It returns a
+    pointer to the current name in <parameter>description</parameter>,
+    stored in memory internal to the event source. The memory is
+    invalidated when the event source is destroyed or the descriptive
+    name is changed.</para>
+
+    <para>Event source objects generally have no description set when
+    they are created, except for UNIX signal event sources created
+    with
+    <citerefentry><refentrytitle>sd_event_add_signal</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+    whose descriptive name is initialized to the signal's C constant
+    name (e.g. <literal>SIGINT</literal> or
