How do I know what the maximum allowed filename length is for a
given file system?
As someone else pointed out, you can use pathconf() if you really
need this information. However, it's best not to make any assumptions
about the maximum lengths of filenames or pathnames, because doing so
only causes problems when those assumptions turn out not to be correct.
I would recommend that you don't make any assumptions, and just code
your application as if there is no limit on filename lengths. You
might be able to justify limiting the length of a filename or
pathname in a GUI field, but it will be tricky to get this exactly
right because of things like mount points, symbolic links and aliases
(for instance, you can't rely on things being on the same filesystem
just because they start with the same /Volumes/<whatever>/).
Kind regards,
Alastair.
