<title>Description</title>
<para><function>sd_bus_message_rewind()</function> moves the "read pointer" in the message
<parameter>m</parameter> to either the begining 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>
</refsect1>
<refsect1>
<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.
