+
+    <para><function>sd_event_set_name()</function> can be used to set
+    an arbitrary name for the event source
+    <parameter>source</parameter>. This name will be used in error
+    messages generated by
+    <citerefentry><refentrytitle>sd-event</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    for this source. Specified <parameter>name</parameter> must point
+    to a <constant>NUL</constant>-terminated string or be
+    <constant>NULL</constant>. In the latter case, the name will be
+    unset. The string is copied internally, so the
+    <parameter>name</parameter> argument is not referenced after the
+    function returns.</para>
+
+    <para><function>sd_event_set_name()</function> can be used to
+    query the current name assigned to source
+    <parameter>source</parameter>. It returns a pointer to the current
+    name (possibly <constant>NULL</constant>) in
+    <parameter>name</parameter>.</para>
