  68
  69     <para>The <function>sd_bus_message_append</function> function can be
  70     used to append an array of strings to message
  71     <parameter>m</parameter>. The parameter <parameter>l</parameter>
  72     shall point to a <constant>NULL</constant>-terminated array of pointers
  73     to <constant>NUL</constant>-terminated strings. Each string must
  74     satisfy the same constraints as described for the
  75     <literal>s</literal> type in
  76     <citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
  77     </para>
  78
  79     <para>The memory pointed at by <parameter>p</parameter> and the
  80     contents of the strings themselves are copied into the memory area
  81     containing the message and may be changed after this call. Note
  82     that the signature of <parameter>l</parameter> parameter is to be
  83     treated as <type>const char *const *</type>, and the contents
  84     will not be modified.</para>

  89
  90     <para>On success, this call returns 0 or a positive integer. On
  91     failure, a negative errno-style error code is returned.</para>
