[Octave-bug-tracker] [bug #44682] Fullfile does not support network share addresses

[Philip Nienhuis]

Follow-up Comment #18, bug #44682 (project octave):

(picking up again)

@Rik:
The OP's suggestion is a bit too simple as even on Windows, UNC file path
constructs should have a first part of the form '\\server\sharename', at the
very least ~ '\\a\b'. Also some tests have to be adapted.

So, should we include a check for valid UNC full filenames, incl. a
warning/error message, or let valid filenames be the responsibility of the
user?

In case of the former a fairly simple regexp would do but then I'd also check
for valid characters in at least 'server' and 'share', something like:

! isempty (regexp (filename, '\\\\[^<>:"/\\|\?\*]+\\[^<>:"/\\|\?\*]+.*',
"match"))


In the latter case even '\\' would be a possible result of fullfile.m.
