Common functions that many Drupal modules will need to reference.

Code

function drupal_render_cache_set(&$markup, $elements) {

  // Create the cache ID for the element.
  if (!in_array($_SERVER['REQUEST_METHOD'], array(
    'GET',
    'HEAD',
  )) || !($cid = drupal_render_cid_create($elements))) {
    return FALSE;
  }

  // Cache implementations are allowed to modify the markup, to support
  // replacing markup with edge-side include commands. The supporting cache
  // backend will store the markup in some other key (like
  // $data['#real-value']) and return an include command instead. When the
  // ESI command is executed by the content accelerator, the real value can
  // be retrieved and used.
  $data['#markup'] =& $markup;

  // Persist attached data associated with this element.
  $attached = drupal_render_collect_attached($elements, TRUE);
