Hello, I have some simple code that opens a file on the IFS for reading. This was working, but then I started getting NULL from the fopen() call. When I check errno it is set to ECONVERT or "Conversion Error." Why in the world would I get a conversion error just opening the file? I know the question is a bit vague, but it really doesn't make sense... it is just a regular old fopen() call on a text file. fp = fopen(fname,"r"); Anyone see this behavior before?
