53
54     <para>The <function>sd_bus_message_append</function> function can be
55     used to append an array of strings to message
56     <parameter>m</parameter>. The parameter <parameter>l</parameter>
57     shall point to a <constant>NULL</constant>-terminated array of pointers
58     to <constant>NUL</constant>-terminated strings. Each string must
59     satisfy the same constraints as described for the
60     <literal>s</literal> type in
61     <citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
62     </para>
63
64     <para>The memory pointed at by <parameter>p</parameter> and the
65     contents of the strings themselves are copied into the memory area
66     containing the message and may be changed after this call. Note
67     that the signature of <parameter>l</parameter> parameter is to be
68     treated as <type>const char *const *</type>, and the contents
69     will not be modified.</para>
