Well, I'm still of different opinion. The basic set of error codes should
be shared on FindFirst level (BTW as opposed to GetLastError, which
clearly returns last OS error and thus is not portable). I consider at
least the following to belong to this basic set (in this particular case):
- No more files (18)
- Path not found (3)
- Access denied (5)
I might have forgotten other important ones (writing this from the top of
my head on the way from Frankfurt to Bonn).
