+
+    <para><function>sd_bus_slot_unref()</function> decreases the reference counter of
+    <parameter>slot</parameter> by one. Once the reference count has dropped to zero, slot object is
+    destroyed and cannot be used anymore, so further calls to <function>sd_bus_slot_ref()</function>
+    or <function>sd_bus_slot_unref()</function> are illegal.</para>
+
+    <para><function>sd_bus_slot_unrefp()</function> is similar to
+    <function>sd_bus_slot_unref()</function> but takes a pointer to a pointer to an
+    <type>sd_bus_slot</type> object. This call is useful in conjunction with GCC's and LLVM's <ulink
+    url="https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html">Clean-up Variable
+    Attribute</ulink>. See
+    <citerefentry><refentrytitle>sd_bus_new</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    for an example how to use the cleanup attribute.</para>
+
+    <para><function>sd_bus_slot_ref()</function> and <function>sd_bus_slot_unref()</function>
+    execute no operation if the passed in bus object address is
+    <constant>NULL</constant>. <function>sd_bus_slot_unrefp()</function> will first dereference
+    its argument, which must not be <constant>NULL</constant>, and will execute no operation if
