Description
To avoid remote code-execution every backend function that is supposed to be callable by the CPAINT frontend cpaint.call() must be published to the CPAINT backend by this function.
Note: Obviously, all CPAINT API functions must be registered before cpaint.start() is called.
Note (PHP): CPAINT is able to use methods of an object as API functions. If you would like to do so, you must pass an array with a reference to the object and the method name to CPAINT, like this:
$cp->register ( array ( &$my_object, 'object_method' ) );
Static class functions can be registered like this:
$cp->register ( array ( 'class_name', 'object_method' ) );
If you're using only standalone functions you may simply suply the function name:
$cp->register ( 'function_name' );
This behaviour is consistent with that of PHPs builtin functions call_user_func() and similar.
Note: The second and third argument input and output are present for forward-compatibility reasons only. They are entirely optional and unused by the CPAINT code.
