  66
  67     <para>The <function>sd_bus_message_append</function> function can be
  68     used to append an array of strings to message
  69     <parameter>m</parameter>. The parameter <parameter>l</parameter>
  70     shall point to a <constant>NULL</constant>-terminated array of pointers
  71     to <constant>NUL</constant>-terminated strings. Each string must
  72     satisfy the same constraints as described for the
  73     <literal>s</literal> type in
  74     <citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
  75     </para>
  76
  77     <para>The memory pointed at by <parameter>p</parameter> and the
  78     contents of the strings themselves are copied into the memory area
  79     containing the message and may be changed after this call. Note
  80     that the signature of <parameter>l</parameter> parameter is to be
  81     treated as <type>const char *const *</type>, and the contents
  82     will not be modified.</para>

  86     <title>Return Value</title>
  87
  88     <para>On success, this call returns 0 or a positive integer. On
  89     failure, a negative errno-style error code is returned.</para>
