    <title>Description</title>

    <para>The <function>sd_bus_message_append</function> function can be
    used to append an array of strings to message
    <parameter>m</parameter>. The parameter <parameter>l</parameter>
    shall point to a <constant>NULL</constant>-terminated array of pointers
    to <constant>NUL</constant>-terminated strings. Each string 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 memory pointed at by <parameter>p</parameter> and the
    contents of the strings themselves are copied into the memory area
    containing the message and may be changed after this call. Note
    that the signature of <parameter>l</parameter> parameter is to be
    treated as <type>const char *const *</type>, and the contents
    will not be modified.</para>
  </refsect1>

  <refsect1>
    <title>Return Value</title>

    <para>On success, this call returns 0 or a positive integer. On
    failure, a negative errno-style error code is returned.</para>
