Support » Plugins » a question about wp_list_bookmarks

  • in wp-includes/bookmark-template.php i see:

    $output = apply_filters( 'wp_list_bookmarks', $output );

    can anyone explain to me why we need to apply a filter here? Also, i’ve grep-ed the code tree and it seems that ‘wp_list_bookmarks’ was not defined as a filter?

    thx in advance:)
