drupal_autoload_interface
function drupal_autoload_interface
drupal_autoload_interface($interface)
Confirms that an interface is available.
This function is rarely called directly. Instead, it is registered as an spl_autoload() handler, and PHP calls it for us when necessary.
Parameters
$interface: The name of the interface to check or load.
Return value
TRUE if the interface is currently available, FALSE otherwise.
