[vtkusers] vtkAVSucdReader does not create error event?

[Florian Bruckner]

hi, 

I would like to write a generic unstructured grid reader function
(class). Therefor I want simply add vtkAVSucdReader,
vtkXMLUnstructredGridReader, vtkUnstructuredGridReader and possibly some
others into a list and try one after another to read the datafile. I
assumed that each of theses readers would raise an error event if
something goes wrong reading the file, but unfortunately vtkAVSucdReader
seems to never fail! 

is it very complicated to add some error conditions to the reader code?
how could i manage this, or is this already planned for future versions?

thanks
