+    <para><function>sd_bus_message_set_expect_reply()</function> sets or clears the
+    <constant>NO_REPLY_EXPECTED</constant> flag on the message <parameter>m</parameter>. This flag
+    matters only for method call messages and is used to specify that no method return or error
+    reply is expected. It is ignored for other types. Thus, for a method call message, calling
+    <programlisting>sd_bus_message_set_expect_reply(…, 0)</programlisting> sets the flag and
+    suppresses the reply.</para>
+
+    <para><function>sd_bus_message_get_expect_reply()</function> checks if the
+    <constant>NO_REPLY_EXPECTED</constant> flag is set on the message <parameter>m</parameter>. It
+    will return positive if it is not set, and zero if it is.</para>
+
+    <para><function>sd_bus_message_set_auto_start()</function> sets or clears the
+    <constant>NO_AUTO_START</constant> flag on the message <parameter>m</parameter>. When the flag
+    is set the bus must not launch an owner for the destination name in response to this message.
+    Calling
+    <programlisting>sd_bus_message_set_auto_start(…, 0)</programlisting> sets the flag.
+    </para>
