  44
  45     <para>The <function>sd_bus_message_append</function> function can be
  46     used to append an array of strings to message
  47     <parameter>m</parameter>. The parameter <parameter>l</parameter>
  48     shall point to a <constant>NULL</constant>-terminated array of pointers
  49     to <constant>NUL</constant>-terminated strings. Each string must
  50     satisfy the same constraints as described for the
  51     <literal>s</literal> type in
  52     <citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
  53     </para>
  54
  55     <para>The memory pointed at by <parameter>p</parameter> and the
  56     contents of the strings themselves are copied into the memory area
  57     containing the message and may be changed after this call. Note
  58     that the signature of <parameter>l</parameter> parameter is to be
  59     treated as <type>const char *const *</type>, and the contents
  60     will not be modified.</para>
