Re: [Openexr-devel] Input/output error

[Ken McGaugh]

This is using version 1.2.1.  The shake translater is custom, while
the prman one is ILM's published display driver (with minor changes).

We are catching all exceptions, and in this case it is an Iex::EioExc
exception initially caught by Imf::OutputFile::writePixels().  Ultimately
I think it is being thrown by Imf::StdOFStream::write(), although it may
be in one of the other routines which does a seek.

Would modifying the ofstream's buffer settings to alleviate this kind
of problem?  Or would doing

    ios::sync_with_stdio(false);

help at all?

Thanks.
