+    <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_get_destination()</function>,
+    <function>sd_bus_message_get_path()</function>,
+    <function>sd_bus_message_get_interface()</function>, and
+    <function>sd_bus_message_get_member()</function> return the destination, path, interface, and
+    member fields from <parameter>message</parameter> header. The return value will be
+    <constant>NULL</constant> is <parameter>message</parameter> is <constant>NULL</constant> or the
+    message is of a type that doesn't use those fields or the message doesn't have them set. See
+    <citerefentry><refentrytitle>sd_bus_message_new_method_call</refentrytitle><manvolnum>3</manvolnum></citerefentry> and
+    <citerefentry><refentrytitle>sd_bus_message_set_destination</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    for more discussion of those values.</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>
+
+    <para><function>sd_bus_message_get_sender()</function> returns the sender field from
+    <parameter>message</parameter>.</para>
+
+    <para>When a string is returned, it is a pointer to internal storage, and may not be modified or
+    freed. It is only valid as long as the <parameter>message</parameter> remains referenced and
+    this field hasn't been changed by a different call.</para>

+    <title>Return Value</title>
+
+    <para>On success, these calls return 0 or a positive integer. On failure, these calls return a
+    negative errno-style error code.</para>
