CiviCRM Community Forums (archive)

The following code worked on 4.1, but now that I have upgraded to 4.2 it doesn't anymore:

$params = Array('contact_id' => $cid, 'location_type_id' => array( 'IN' => array( '0' => $HOME_ID, '1' => $WORK_ID)));
$emails = call_civicrm('Email', 'get', $params);

Can someone tell me (1) How this should be done in the latest version of CiviCRM, and (2) Where the "real" documentation for things like this are stored. Do I need to simply read all the api code to learn these advanced techniques because the documentation on the website and the example files only do the most rudimentary things with the API.
