+
+    <para><function>sd_bus_slot_set_description()</function> sets the description string
+    that is used in logging to the specified string. The string is copied internally
+    and freed when the bus slot object is deallocated. The
+    <parameter>description</parameter> argument may be <constant>NULL</constant>, in
+    which case the description is unset.</para>
+
+    <para><function>sd_bus_slot_get_description()</function> returns a description string in
+    <parameter>description</parameter>. If the string is not set, e.g. with
+    <function>sd_bus_slot_set_description()</function>, and the slot is a bus match callback slot,
+    the match string will be returned. Otherwise, <constant>-ENXIO</constant> is returned.
