Note that this function **requires** you to manually pass by reference:
<?php
newt_init();
newt_get_screen_size($cols, $rows); // This won't work
# PHP Notice: Undefined variable: cols in [file] on line 5
# PHP Notice: Undefined variable: rows in [file] on line 5
newt_get_screen_size(&$cols, &$rows); // This, however, works fine
newt_finished();
?>
