<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>
</refsect1>
<refsect1>
<title>Return Value</title>
<para>On success, this call returns 0 or a positive integer. On
failure, a negative errno-style error code is returned.</para>

<title>Notes</title>
<para>The <function>sd_bus_append_append_strv()</function> function
described here is available as a shared library, which can be
compiled and linked to with the
<constant>libsystemd</constant> <citerefentry project='die-net'><refentrytitle>pkg-config</refentrytitle><manvolnum>1</manvolnum></citerefentry>
file.</para>
