functionality of checkref in perl

Hello List,


So I really don't unterstand, how to use the checkref-function in the
Perl-Module, in last parameter I am able to submit $output-parameter,
but how I get the output? the only out I get is:

999:1 checked:0 skipped:0 failed

For this, I used the following test-script:

use strict;
use warnings;

use RefDBClient::Client;

my $client= new RefDBClient::Client();
my $data = new RefDBClient::Risdata();


$client->set_conninfo("127.0.0.1","9734","xxxxxxxx",
"xxxxxx","xxxxxx","","");
$data->read_ris("./test");

print $client->refdb_checkref($data, "ris", "utf-8", "scrn");


while the dataset in test is in database.

Thanx for support,

m.
