>Data_Wrap_Struct(klass, mark, free, ptr)


if you use
Data_Wrap_Struct(klass, 0, free, ptr)
or
Data_Wrap_Struct(klass, 0, -1, ptr)

the pointer and the data will be freed
if you use
Data_Wrap_Struct(klass, 0, 0, ptr)
the pointer will not be deleted or freed


the problem is: sometimes its bad if the GC deleted objects if there are 
stored in other c(++) objects (like an window manager which holds the 
windows) this way you need Data_Wrap_Struct(klass, 0, 0, ptr)


PS: i does not realy know that mark do, so i does not use it
