+
+    <para><function>sd_bus_message_skip()</function> is somewhat similar to
+    <citerefentry><refentrytitle>sd_bus_message_read</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+    but instead of reading the contents of the message, it only moves the "read pointer". Subsequent
+    read operations will read the elements that are after the elements that were skipped.</para>
+
+    <para>The <parameter>types</parameter> argument has the same meaning as in
+    <function>sd_bus_message_read()</function>. It may also be <constant>NULL</constant>, to skip a
+    single element of any type.</para>

+    <title>Return Value</title>
+
+    <para>On success, <function>sd_bus_message_skip()</function> returns 0 or a positive integer. On
