10 | * The formatted output of a list of bookmarks. |

14 | * |
15 | * The output is formatted as HTML with no way to change that format. However, |
16 | * what is between, before, and after can be changed. The link itself will be |
17 | * HTML. |
18 | * |
19 | * This function is used internally by wp_list_bookmarks() and should not be |
20 | * used by themes. |
21 | * |
22 | * The defaults for overwriting are: |

26 | * of the bookmark. |

32 | * bookmarks. |
33 | * 'after' - Default is '</li>' (string). The html or text to append to each |
34 | * bookmarks. |
35 | * 'link_before' - Default is '' (string). The html or text to prepend to each |
36 | * bookmarks inside the <a> tag. |
37 | * 'link_after' - Default is '' (string). The html or text to append to each |
38 | * bookmarks inside the <a> tag. |
39 | * 'between' - Default is '\n' (string). The string for use in between the link, |
40 | * description, and image. |
41 | * 'show_rating' - Default is 0 (integer). Whether to show the link rating. |
