Comment(by ckeen):

 I am not sure what you want to do in case of this error. What I would do
 in a file selection dialog: catch the condition and present the message to
 the user and then try again.

 What should a program do if the file does not exist? If I would expect a
 file to exist I would do a fstat call first anyhow, so I could create the
 file if necessary.

 Unless there is a clear advantage in being able to tell the difference
 between file not found, file unreachable (network mounts), file unwritable
 (permissions or disk full?) and what not, I would like to dodge the issue
 at large.
