[Paraview] Problems writing binary vtu file

[Aleksejs Fomins]

Dear Paraview,

I tried to extend my VTU writer to write into binary format. I have tried either writing floats using Float32 format and doubles using Float64 format, both fail the same way. I write into binary by using

file.write( (char*) &binarydata, sizeof(BinaryType));

In both cases, Paraview complains that there is an invalid token immediately at the beginning of binary output within the first DataArray clause.

Could someone please hint me as of what I am doing wrong.

Regards,
Aleksejs
