* Loads a module include file.

* module_load_include('inc', 'node', 'node.admin');
* // Load content_types.inc from the node module.
* module_load_include('inc', 'node', 'content_types');
* @endcode
*
* Do not use this function to load an install file, use module_load_install()
* instead. Do not use this function in a global context since it requires
* Drupal to be fully bootstrapped, use require_once DRUPAL_ROOT . '/path/file'
* instead.
*
* @param $type
* The include file's type (file extension).
* @param $module
* The module to which the include file belongs.
* @param $name
* (optional) The base file name (without the $type extension). If omitted,
* $module is used; i.e., resulting in "$module.$type" by default.
*
* @return bool|string
* The name of the included file, if successful; FALSE otherwise.
*
* @deprecated in drupal:9.4.0 and is removed from drupal:11.0.0.
* Use \Drupal::moduleHandler()->loadInclude($module, $type, $name = NULL).
* Note that including code from uninstalled extensions is no longer
* supported.
