/**

 * Retrieve paginated link for archive post pages.

 *

 * Technically, the function can be used to create paginated link list for any

 * area. The 'base' argument is used to reference the url, which will be used to

 * create the paginated links. The 'format' argument is then used for replacing

 * the page number. It is however, most likely and by default, to be used on the

 * archive post pages.

 *

 * The 'type' argument controls format of the returned value. The default is

 * 'plain', which is just a string with the links separated by a newline

 * character. The other possible values are either 'array' or 'list'. The

 * 'array' value will return an array of the paginated link list to offer full

 * control of display. The 'list' value will place all of the paginated links in

 * an unordered HTML list.

 *

 * The 'total' argument is the total amount of pages and is an integer. The

 * 'current' argument is the current page number and is also an integer.

 *

 * An example of the 'base' argument is "http://example.com/all_posts.php%_%"

 * and the '%_%' is required. The '%_%' will be replaced by the contents of in

 * the 'format' argument. An example for the 'format' argument is "?page=%#%"

 * and the '%#%' is also required. The '%#%' will be replaced with the page

 * number.

 *

 * You can include the previous and next links in the list by setting the

 * 'prev_next' argument to true, which it is by default. You can set the

 * previous text, by using the 'prev_text' argument. You can set the next text

 * by setting the 'next_text' argument.

 *

 * If the 'show_all' argument is set to true, then it will show all of the pages

 * instead of a short list of the pages near the current page. By default, the

 * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'

 * arguments. The 'end_size' argument is how many numbers on either the start

 * and the end list edges, by default is 1. The 'mid_size' argument is how many

 * numbers to either side of current page, but not including current page.

 *

 * It is possible to add query vars to the link by using the 'add_args' argument

 * and see {@link add_query_arg()} for more information.

 *

 * The 'before_page_number' and 'after_page_number' arguments allow users to

 * augment the links themselves. Typically this might be to add context to the

 * numbered links so that screen reader users understand what the links are for.

 * The text strings are added before and after the page number - within the

 * anchor tag.

 *

 * @since 2.1.0

 *

 * @param string|array $args Optional. Override defaults.

 * @return array|string String of page links or array of page links.
