function module_load_include

Loads a module include file.

Examples:

// Load node.admin.inc from the node module.
module_load_include('inc', 'node', 'node.admin');

// Load content_types.inc from the node module.
module_load_include('inc', 'node', 'content_types');

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.

Parameters

$type: The include file's type (file extension).

$module: The module to which the include file belongs.

$name: (optional) The base file name (without the $type extension). If omitted, $module is used; i.e., resulting in "$module.$type" by default.

Return value

The name of the included file, if successful; FALSE otherwise.
