17 File Objects Routines

17 Managing Unknown Objects

QuickDraw3D creates an unknown object when it encounters an unrecognized type of object while reading a metafile. Your application might know how to handle objects of that type, so QuickDraw3D provides routines that you can use to get the type and contents of an unknown object.

You cannot explicitly create an unknown object.<8bat>u
