Changes several attributes of an object at the same time. How the
object interprets the new attributes depends on the class.
INPUTS
class
Assume that the object is of this class.
object
Change the attributes of this object
value
pairs. The last
attribute in this list must be TAG_END or TAG_DONE.
The value for this last attribute is not examined (ie.
you need not specify it).
RESULT
Depends in the class. For gadgets, this value is non-zero if
they need redrawing after the values have changed. Other classes
will define other return values.
The macros AROS_SLOWSTACKTAGS and AROS_SLOWSTACKMETHODS now use
AROS_TAGRETURNTYPE and AROS_METHODRETURNTYPE to create a variable
called retval in which the use suplied part of the function must store
the return value. If these types are not defined, then the types
default to IPTR.
