[Bug-xorriso] How can I calculate the max. Filesize with a given available sector count?

[sean loony]

Hello,

example:
cdrskin dev=/dev/sr0 -minfo
...
Track  Sess Type   Start Addr End Addr   Size
==============================================
    1     1 Blank  0          336072     336073

Next writable address:              0
Remaining writable size:            336073

Here we have a disc with 336073 2k Sectors => 688277504 bytes.

Now I want to record only one file to this disc with maximum usable
size. ISO9660 has some overhead, lead-in, lead-out,...
How can I get the max. usable size for a file in ISO9660?
Is there a parameter for xorriso that tells the programm 'look here
we have a disc with 336073 sectors tell me the free space in an iso9660
with rockridge extension for this sized disc'?

Thank you for your answers
