文档:

The formatted output of a list of bookmarks.

The $bookmarks array must contain bookmark objects and will be iterated over to retrieve the bookmark to be used in the output.

The output is formatted as HTML with no way to change that format. However, what is between, before, and after can be changed. The link itself will be HTML.

This function is used internally by wp_list_bookmarks() and should not be used by themes.
