+
+    <para><function>sd_bus_message_rewind()</function> moves the "read pointer" in the message
+    <parameter>m</parameter> to either the beginning of the message (if
+    <parameter>complete</parameter> is true) or to the beginning of the currently open container. If
+    no container is open, <parameter>complete</parameter> has no effect.</para>

+    <title>Return Value</title>
+
+    <para>
+      On success, this function returns 0 or a positive integer. The value is zero if the current
+      container or whole message in case no container is open is empty, and positive otherwise. On
+      failure, it returns a negative errno-style error code.
