  21 /*  SYNOPSIS */
  22         Object * obj,
  23         Msg      message)
  24
  25 /*  FUNCTION
  26         Invokes a method on a BOOPSI object. The dispatcher of the class the
  27         object is inherited from is called. For more information about methods
  28         a class supports, see the class documentation.
  29
  30     INPUTS
  31         obj - The object on which the method is to be performed.
  32         message - The message. The first field is the same for all methods and
  33                   specifies which method is to be invoked (see
  34                   <intuition/classusr.h>).
  35
  36     RESULT
  37         Class and method dependent. See the class documentation. A value of 0
  38         can be a valid return code but can also mean that a method is not
  39         supported.
