+    <title>Description</title>
+
+    <para>The functions
+    <function>sd_bus_message_append_string_memfd</function> and
+    <function>sd_bus_message_append_string_iovec</function> can be
+    used to append a single string (item of type <literal>s</literal>)
+    to message <parameter>m</parameter>.</para>
+
+    <para>In case of
+    <function>sd_bus_message_append_string_memfd</function>, the
+    contents of <parameter>memfd</parameter> are the string. They must
+    satisfy the same constraints as described for the
+    <literal>s</literal> type in
+    <citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.</para>
+
+    <para>In case of
+    <function>sd_bus_message_append_string_iovec</function>, the
+    payload of <parameter>iov</parameter> is the string. It must
+    satisfy the same constraints as described for the
+    <literal>s</literal> type in
+    <citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.</para>
+
+    <para>The <parameter>iov</parameter> argument must point to
+    <parameter>n</parameter> <structname>struct iovec</structname>
+    structures. Each structure may have the
+    <structname>iov_base</structname> field set, in which case the
+    memory pointed to will be copied into the message, or unset, in
+    which case a block of spaces (ASCII 32) of length
+    <structname>iov_len</structname> will be inserted. The
+    memory pointed at by <parameter>iov</parameter> may be changed
+    after this call.</para>
+
+    <para>The
+    <function>sd_bus_message_append_string_space</function> function appends
+    space for a string to message <parameter>m</parameter>. It behaves
+    similar to <function>sd_bus_message_append_basic</function> with
+    type <literal>s</literal>, but instead of copying a string into
+    the message, it returns a pointer to the destination area to
+    the caller in pointer <parameter>p</parameter>. Space for the string
+    of length <parameter>size</parameter> plus the terminating
+    <constant>NUL</constant> is allocated.</para>

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