+ <para><function>sd_bus_path_encode_many()</function> works like
+ its counterpart <function>sd_bus_path_encode()</function>, but
+ takes a path template as argument and encodes multiple labels
+ according to its embedded directives. For each
+ <literal>%</literal> character found in the template, the caller
+ must provide a string via varargs, which will be encoded and
+ embedded at the position of the <literal>%</literal> character.
+ Any other character in the template is copied verbatim into the
+ encoded path.</para>
+
+ <para><function>sd_bus_path_decode_many()</function> does the
+ reverse of <function>sd_bus_path_encode_many()</function>. It
+ decodes the passed object path according to the given
+ path template. For each <literal>%</literal> character in the
+ template, the caller must provide an output storage
+ (<literal>char **</literal>) via varargs. The decoded label
+ will be stored there. Each <literal>%</literal> character will
+ only match the current label. It will never match across labels.
+ Furthermore, only a single directive is allowed per label.
+ If <literal>NULL</literal> is passed as output storage, the
+ label is verified but not returned to the caller.</para>
