[Openexr-devel] Implementing low level file IO

[Brad Hards]

I'm looking at the manual section 7.2 (Custom Low-Level File I/O), and having 
a few concerns. I think I need to do this to get good integration into 
Qt4/KDE4 - so I can use a QIODevice, which is the base class for all kinds of 
IO concepts (network sockets, files, generic buffers and process output).

The problem is that sometimes a QIODevice doesn't support random access - you 
cannot seek. So the question is "what is OpenEXR going to do if tellg just 
returns zero"? If it is going to break, I'll just disable reading files from 
non-seekable devices, but some indication of the dragons lurking might be 
very useful before I get too much into this.
