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