<title>Description</title>
<para><function>sd_bus_message_seal()</function> finishes the message <parameter>m</parameter>
and prepares it for transmission using
<citerefentry><refentrytitle>sd_bus_send</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
<parameter>cookie</parameter> specifies the identifier used to match the message reply to its
corresponding request. <parameter>timeout_usec</parameter> specifies the maximum time in
microseconds to wait for a reply to arrive.</para>
<para>Note that in most scenarios, it's not necessary to call this function directly.

<citerefentry><refentrytitle>sd_bus_call_async</refentrytitle><manvolnum>3</manvolnum></citerefentry> and
<citerefentry><refentrytitle>sd_bus_send</refentrytitle><manvolnum>3</manvolnum></citerefentry>
will seal any given messages if they have not been sealed yet.</para>

<title>Return Value</title>

negative errno-style error code.</para>
