How to change drupal pagination?

Question

CMS

I needed to change the pagination function in Drupal 6. I defined the mytheme_pager () function in the tepmplate.php file, but Drupal does not respond to it, displays everything the same way. What could be the reason?
theme_pager() code in includes/pager.inc
In template.php I created the same function called mytheme_pager() and changed the classes

function theme_pager($tags = array(), $limit = 10, $element = 0, $parameters = array(), $quantity = 9) {
  global $pager_page_array, $pager_total;

  if(drupal_is_front_page()) {
    return '';
  }

  // Calculate various markers within this pager piece:
  // Middle is used to "center" pages around the current page.
  $pager_middle = ceil($quantity / 2);
  // current is the page we are currently paged to
  $pager_current = $pager_page_array[$element] + 1;
  // first is the first page listed by this pager piece (re quantity)
  $pager_first = $pager_current - $pager_middle + 1;
  // last is the last page listed by this pager piece (re quantity)
  $pager_last = $pager_current + $quantity - $pager_middle;
  // max is the maximum page number
  $pager_max = $pager_total[$element];
  // End of marker calculations.

  // Prepare for generation loop.
  $i = $pager_first;
  if ($pager_last > $pager_max) {
    // Adjust "center" if at end of query.
    $i = $i + ($pager_max - $pager_last);
    $pager_last = $pager_max;
  }
  if ($i <= 0) {
    // Adjust "center" if at start of query.
    $pager_last = $pager_last + (1 - $i);
    $i = 1;
  }
  // End of generation loop preparation.

  $li_first = theme('pager_first', (isset($tags[0]) ? $tags[0] : t('« first')), $limit, $element, $parameters);
  $li_previous = theme('pager_previous', (isset($tags[1]) ? $tags[1] : t('‹ previous')), $limit, $element, 1, $parameters);
  $li_next = theme('pager_next', (isset($tags[3]) ? $tags[3] : t('next ›')), $limit, $element, 1, $parameters);
  $li_last = theme('pager_last', (isset($tags[4]) ? $tags[4] : t('last »')), $limit, $element, $parameters);

  if ($pager_total[$element] > 1) {
    if ($li_first) {
      $items[] = array(
        'class' => 'pager-first',
        'data' => $li_first,
      );
    }
    if ($li_previous) {
      $items[] = array(
        'class' => 'pager-previous',
        'data' => $li_previous,
      );
    }

    // When there is more than one page, create the pager list.
    if ($i != $pager_max) {
      if ($i > 1) {
        $items[] = array(
          'class' => 'pager-ellipsis',
          'data' => '…',
        );
      }
      // Now generate the actual pager piece.
      for (; $i <= $pager_last && $i <= $pager_max; $i++) {
        if ($i < $pager_current) {
          $items[] = array(
            'class' => 'pager-item',
            'data' => theme('pager_previous', $i, $limit, $element, ($pager_current - $i), $parameters),
          );
        }
        if ($i == $pager_current) {
          $items[] = array(
            'class' => 'pager-current',
            'data' => $i,
          );
        }
        if ($i > $pager_current) {
          $items[] = array(
            'class' => 'pager-item',
            'data' => theme('pager_next', $i, $limit, $element, ($i - $pager_current), $parameters),
          );
        }
      }
      if ($i < $pager_max) {
        $items[] = array(
          'class' => 'pager-ellipsis',
          'data' => '…',
        );
      }
    }
    // End generation.
    if ($li_next) {
      $items[] = array(
        'class' => 'pager-next',
        'data' => $li_next,
      );
    }
    if ($li_last) {
      $items[] = array(
        'class' => 'pager-last',
        'data' => $li_last,
      );
    }
    return theme('item_list', $items, NULL, 'ul', array('class' => 'pager'));
  }
}
