Invokes a method on a BOOPSI object. The dispatcher of the class the
object is inherited from is called. For more information about methods
a class supports, see the class documentation.

obj - The object on which the method is to be performed.
message - The message. The first field is the same for all methods and
specifies which method is to be invoked (see

RESULT
Class and method dependent. See the class documentation. A value of 0
can be a valid return code but can also mean that a method is not
supported.
