4564 + * Retrieves paginated links for archive post pages.
4565 + *
4566 + * Technically, the function can be used to create paginated link list for any
4567 + * area. The 'base' argument is used to reference the url, which will be used to
4568 + * create the paginated links. The 'format' argument is then used for replacing
4569 + * the page number. It is however, most likely and by default, to be used on the
4570 + * archive post pages.
4571 + *
4572 + * The 'type' argument controls format of the returned value. The default is
4573 + * 'plain', which is just a string with the links separated by a newline
4574 + * character. The other possible values are either 'array' or 'list'. The
4575 + * 'array' value will return an array of the paginated link list to offer full
4576 + * control of display. The 'list' value will place all of the paginated links in
4577 + * an unordered HTML list.
4578 + *
4579 + * The 'total' argument is the total amount of pages and is an integer. The
4580 + * 'current' argument is the current page number and is also an integer.
4581 + *
4582 + * An example of the 'base' argument is "http://example.com/all_posts.php%_%"
4583 + * and the '%_%' is required. The '%_%' will be replaced by the contents of in
4584 + * the 'format' argument. An example for the 'format' argument is "?page=%#%"
4585 + * and the '%#%' is also required. The '%#%' will be replaced with the page
4586 + * number.
4587 + *
4588 + * You can include the previous and next links in the list by setting the
4589 + * 'prev_next' argument to true, which it is by default. You can set the
4590 + * previous text, by using the 'prev_text' argument. You can set the next text
4591 + * by setting the 'next_text' argument.
4592 + *
4593 + * If the 'show_all' argument is set to true, then it will show all of the pages
4594 + * instead of a short list of the pages near the current page. By default, the
4595 + * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
4596 + * arguments. The 'end_size' argument is how many numbers on either the start
4597 + * and the end list edges, by default is 1. The 'mid_size' argument is how many
4598 + * numbers to either side of current page, but not including current page.
4599 + *
4600 + * It is possible to add query vars to the link by using the 'add_args' argument
4601 + * and see add_query_arg() for more information.
4602 + *
4603 + * The 'before_page_number' and 'after_page_number' arguments allow users to
4604 + * augment the links themselves. Typically this might be to add context to the
4605 + * numbered links so that screen reader users understand what the links are for.

4607 + * anchor tag.
