I think the short answer is you don't use it. There is T_DATA which is
the type of the Ruby object returned by Data_Make_Struct() and
Data_Wrap_Struct().

Hi,

When you want to wrap C pointer into Ruby object in a C extension for
Ruby, and have no need to define any data specific behavior. To tell
the truth, it's not much useful.
