<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 char *const *</type>, and the contents
|
||
will not be modified.</para>
