function drupal_autoload_class

Confirms that a class 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

$class: The name of the class to check or load.

Return value

TRUE if the class is currently available, FALSE otherwise.
