Hey, I'm thinking on porting the Audiere library (unless someone else has) which has nothing but classes with virtual functions and was wondering if I can just use a UDT with function pointers within another UDT that contains it's pointer (Vtable ?)
Example (based off PureBasic port which implements interfaces):
I was following the DirectDraw port for reference. Any help would be greatful.

Code:
Type RefCounted_VTBL
ref As Function() As Long ' Long
unref As Function() As Long ' Long
End Type
Type RefCounted
vtable As RefCounted_VTBL Ptr
End Type
Type AudFile_VTBL
ref As [RefCounted_VTBL or RefCounted?] ' All audiere classes extend RefCounted
File_Read As Function (pbuffer As Long,size As Long) ' long
File_seek As Function(position As Long, SeekMode As Long)As Long ' bool
tell As Function() As Long ' long
