Description

The accessor objc-object-var-value gets or gets the value of the instance variable var-name in the Objective-C foreign object associated with object. The type of value depends on the declared type of the instance variable. If this type is a foreign structure type, then result-pointer should be supplied to the reader, giving a pointer to a foreign object of the correct type that is filled with the value.

Note that it is only possible to access instance variables that are defined in Lisp by define-objc-class, not those inherited from superclasses implemented in Objective-C.
