Keeping a vtkDataSet* after reading

[Evert-jan Vonken]

Hi,

In an DiskIO routine I would like to have a call like
vtkDataSet* readstuff(char* filename);
In readstuff a vtkDataSetReader* io=vtkdataSetReader::New();
instance is created.
After reading, I want to return the DataSet, but after the
vtkDataSet* result=io->getOutput();
  or
    io->setNthOutput(0,result); io->Update();
(which works)
vtkDataSetReader->Delete(); to clean up, the dataset is no longer valid?

How can I prevent Delete() from destroying the dataset,
setting the referenced count of the result or Register() do not seem to
work.
I'm using the nightly release of 12/19/99 on WinNT.

Regards,

Evert-jan
