How come get_links function does not match the cal

Sorry, the hit the wrong button,
here is the code for the function prototype:
function get_links($category = -1, $before = ”, $after = ‘
‘,
$between = ‘ ‘, $show_images = true, $orderby = ‘name’,
$show_description = true, $show_rating = false,
$limit = -1, $show_updated = 1, $echo = true)
here is the call in index.php
get_links(-1, ‘

• ‘, ‘

‘, ”, 0, ‘_rating’, 0, 1, -1, -1)
The function has 11 incoming variables and the call only uses 10. Am I seeing this wrong?

You might want to take a look at the php manual regarding default argument values ??

?? I should have looked. Thanks….thread closed. I will try to post some good descriptions of the links functions soon, thats where this question comes from.
