+ <title>Description</title>
+
+ <para><function>sd_bus_message_set_destination()</function> sets the destination service name for the specified bus
+ message object. The specified name must be a valid unique or well-known service name.</para>
+
+ <para><function>sd_bus_message_set_sender()</function> sets the sender service name for the specified bus message
+ object. The specified name must be a valid unique or well-known service name. This function is useful only for
+ messages to send on direct connections as for connections to bus brokers the broker will fill in the destination
+ field anyway, and the sender field set by original sender is ignored.</para>
