List of possible options?

[Sven Utcke-2]

Hi,

is there a page somewhere describing all the possible options fuse
will take?

In particular, what I am after is to allow my FS to print a list of
all possible options, preferably differentiating between fuse's
general options and my own options, when encountering a -h or --help,
and to give the versions used on -V or --version, along the lines of:

 dcfs 1.2.3
 fuse 2.8.9
fuse API 2.6

Or somesuch.  What would be the easiest way to realise this?

Thanks

Sven

PS: I'm aware of
    http://sourceforge.net/apps/mediawiki/fuse/index.php?title=Option_parsing
    but not much anything else --- in particular I have no clue to get
    the list of options supported by the particular version of Fuse
    I'm linking against (keeping in mind that the version might
    change over time).

You parse the options catching -h|--help. There you output your own
options and also add the -h|--help flag to the options passed down to
lib fuse. Libfuse then prints its own options as well.

Unfortunately that seems to only work with the high level interface.

I use the high-level interface (I'm mostly looking up paths in a
database, so this seemed the way to go), so no problem there.  But
that only prints

Options:
 -h                 print help
 -V                 print version
 -o opt[,opt...]   mount options
 -u                 unmount
 -q                 quiet
 -z                 lazy unmount

doesn't it?  I would like to also print what the actual opts allowed
are.  Or am I missing something obvious?

Thanks

Sven
