Parameters

mixed $data: The variable that will be passed to hook_TYPE_alter() implementations to be altered. The type of this variable depends on the value of the $type argument. For example, when altering a 'form', $data will be a structured array. When altering a 'profile', $data will be an object.

mixed $context1: (optional) An additional variable that is passed by reference.

mixed $context2: (optional) An additional variable that is passed by reference. If more context needs to be provided to implementations, then this should be an associative array as described above.
