[Openexr-devel] validity check on files

[James McPhail]

I hope this hasn't been touched upon in a previous thread.

Is there functionality in the toolkit for determining if an "InputFile" 
is bogus? Specifically, can the toolkit determine, when passed a file 
name, that the given file is not of the EXR format?

I had initially wanted to try

InputFile file(fileName);

then had hoped there would be some flag or function call on this 'file' 
variable or its associated header which would indicate that it was not a 
valid file, however this InputFile constructor throws an exception 
(which I couldn't manage to catch) and then crashes.

Any help would be appreciated.
