That is a reasonable behaviour for a text editor — but only for file names that are explicitly controlled by some program or by the user, not for temporary files. > The programmer didn't > expect that because it is natural to expect each call to a function > that creates a temporary file to create a file under a new name, not > reuse the same name. This is an incorrect assumption. Just like socket numbers are randomly generated in some situations, temp file names are random, and you can't make assumptions about the resulting file name. How about storing, as an attribute of the buffer, a boolean that tells whether the underlying file name is randomly generated (i.e. a temp file), and query this boolean before prompting to the user to refresh the buffer?
