<title>Description</title>
<para>The <function>sd_bus_message_append()</function> function can be
used to append an array of strings to message
<parameter>m</parameter>. The parameter <parameter>l</parameter>
shall point to a <constant>NULL</constant>-terminated array of pointers
to <constant>NUL</constant>-terminated strings. Each string must
satisfy the same constraints as described for the
<literal>s</literal> type in
<citerefentry><refentrytitle>sd_bus_message_append_basic</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
</para>
<para>The memory pointed at by <parameter>p</parameter> and the
contents of the strings themselves are copied into the memory area
containing the message and may be changed after this call. Note
that the signature of <parameter>l</parameter> parameter is to be
treated as <type>const charĀ *constĀ *</type>, and the contents
will not be modified.</para>
