Net::Z3950::ZOOM - Perl extension for invoking the ZOOM-C API.


 use Net::Z3950::ZOOM;
 $conn = Net::Z3950::ZOOM::connection_new($host, $port);
 $errcode = Net::Z3950::ZOOM::connection_error($conn, $errmsg, $addinfo);
 Net::Z3950::ZOOM::connection_option_set($conn, databaseName => "foo");
 # etc.


This module provides a simple thin-layer through to the ZOOM-C functions in the YAZ toolkit for Z39.50 and SRW/U communication. You should not be using this very nasty, low-level API. You should be using the ZOOM module instead, which implements a nice, Perlish API on top of this module, conformant to the ZOOM Abstract API described at

To enforce the don't-use-this-module prohibition, I am not even going to document it. If you really, really, really want to use it, then it pretty much follows the API described in the ZOOM-C documentation at

The only additional (non-ZOOM-C) function provided by this module is event_str(), which takes as its argument an event code such as Net::Z3950::ZOOM::EVENT_SEND_APDU, and returns a corresponding short string.


The ZOOM module, included in the same distribution as this one.
