/**
 * Retrieves paginated links for archive post pages.
 *
 * Technically, the function can be used to create paginated link list for any
 * area. The &#039;base&#039; argument is used to reference the url, which will be used to
 * create the paginated links. The &#039;format&#039; 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 &#039;type&#039; argument controls format of the returned value. The default is
 * &#039;plain&#039;, which is just a string with the links separated by a newline
 * character. The other possible values are either &#039;array&#039; or &#039;list&#039;. The
 * &#039;array&#039; value will return an array of the paginated link list to offer full
 * control of display. The &#039;list&#039; value will place all of the paginated links in
 * an unordered HTML list.
 *
 * The &#039;total&#039; argument is the total amount of pages and is an integer. The
 * &#039;current&#039; argument is the current page number and is also an integer.
 *
 * An example of the &#039;base&#039; argument is &quot;http://example.com/all_posts.php%_%&quot;
 * and the &#039;%_%&#039; is required. The &#039;%_%&#039; will be replaced by the contents of in
 * the &#039;format&#039; argument. An example for the &#039;format&#039; argument is &quot;?page=%#%&quot;
 * and the &#039;%#%&#039; is also required. The &#039;%#%&#039; will be replaced with the page
 * number.
 *
 * You can include the previous and next links in the list by setting the
 * &#039;prev_next&#039; argument to true, which it is by default. You can set the
 * previous text, by using the &#039;prev_text&#039; argument. You can set the next text
 * by setting the &#039;next_text&#039; argument.
 *
 * If the &#039;show_all&#039; 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
 * &#039;show_all&#039; is set to false and controlled by the &#039;end_size&#039; and &#039;mid_size&#039;
 * arguments. The &#039;end_size&#039; argument is how many numbers on either the start
 * and the end list edges, by default is 1. The &#039;mid_size&#039; 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 &#039;add_args&#039; argument
 * and see add_query_arg() for more information.
 *
 * The &#039;before_page_number&#039; and &#039;after_page_number&#039; 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
 * @since 4.9.0 Added the `aria_current` argument.
