Which characters will never appear in a file path?

[alancc]

Among 256 characters, which characters will never appear in a valid
file path definitely? The operating system is Windows(Language aan be
Asian language or other different languages).

I belive 0x00 is one of them. But I need to know the others.

Ask in the newsgroup that deals with your OS. In every OS it's
different and the C++ language does not define what characters are or
aren't appropriate.

I belive 0x00 is one of them. But I need to know the others.

An asterisk and a question mark are usually also invalid (and in more
than one OS, I believe), but, again, this is not the language issue,
it's your OS issue.

Try typing:
msdn valid file names
into gooogle, no quotes.

msdn is sometimes magic.

Then ask in a Windows newsgroup. The answer is probably not trivial.

Right Any interface which uses C strings will have problems with '\0'.

But I need to know the others.

You should also consider *why* you believe you must know. It's
normally best to try to use whatever string you have, instead
of trying to second-guess the file system.
