- <para><function>sd_bus_message_get_cookie()</function> returns
- the transaction cookie of a message. The cookie
- uniquely identifies a message within each bus peer,
- but is not globally unique. It is assigned when a
- message is sent.</para>
-
- <para><function>sd_bus_message_get_reply_cookie()</function>
- returns the transaction cookie of the message the
- specified message is a response to. When a reply
- message is generated for a method call message, its
- cookie is copied over into this field. Note that while
- every message that is transferred is identified by a
- cookie, only response messages carry a reply cookie
- field.</para>
