GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS

See file README for libisoburn and xorriso specific installation instructions.
This file here is rather a manual for advanced usage of ./configure
-------------------------------------------------------------------
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

libisoburn and xorriso. By Vreixo Formoso <metalpain2002@yahoo.es>
and Thomas Schmitt <scdbackup@gmx.net>
Integrated sub project of libburnia-project.org.
http://files.libburnia-project.org/releases/libisoburn-0.5.6.pl00.tar.gz
Copyright (C) 2006-2010 Vreixo Formoso, Thomas Schmitt.
Provided under GPL version 2 or later.
------------------------------------------------------------------------------
libisoburn is a frontend for libraries libburn and libisofs which enables
creation and expansion of ISO-9660 filesystems on all CD/DVD/BD media supported
by libburn. This includes media like DVD+RW, which do not support multi-session
management on media level and even plain disk files or block devices.
The price for that is thorough specialization on data files in ISO-9660
filesystem images. So libisoburn is not suitable for audio (CD-DA) or any
other CD layout which does not entirely consist of ISO-9660 sessions.
xorriso is an application of libisoburn, libisofs, and libburn, which reads
commands from program arguments, files, stdin, or readline.
Its features are also available via a C language API of libisoburn.
Currently they are fully supported on Linux with kernels >= 2.4,
on FreeBSD with ATAPI/CAM support enabled in the kernel, see atapicam(4),
and on OpenSolaris (tested with kernel 5.11).
On other X/Open compliant systems libburn will only offer POSIX i/o with disk
file objects, but no direct MMC operation on CD/DVD/BD drives.
By using this software you agree to the disclaimer at the end of this text:
"... without even the implied warranty ..."
Compilation, First Glimpse, Installation
Dynamic library and compile time header requirements for libisoburn-0.5.6 :
- libburn.so.4 , version libburn-0.8.2 or higher
- libisofs.so.6 , version libisofs-0.6.32 or higher
libisoburn and xorriso will not start with libraries which are older than their
headers seen at compile time.
Obtain libisoburn-0.5.6.pl00.tar.gz, take it to a directory of your choice
and do:
tar xzf libisoburn-0.5.6.pl00.tar.gz
cd libisoburn-0.5.6
Within that directory execute:
./configure --prefix=/usr
make
Then become superuser and execute
make install
which will make available libisoburn.so.1 and the program xorriso.
For the API concepts and calls see
./libisoburn/libisoburn.h
as well as
/usr/lib/libisofs/libisofs.h
/usr/lib/libburn/libburn.h
xorriso
libisoburn comes with a command line and dialog application named xorriso,
which offers a substantial part of libisoburn features to shell scripts and
users. Its file xorriso/README_gnu_xorriso describes the tarball of the
derived package GNU xorriso as first preference for a statically linked
xorriso installation.
The libisoburn installation described above produces a dynamically linked
xorriso binary depending on libburn.so, libisofs.so, libisoburn.so.
After installation documentation is available via
man xorriso
Several alias links point to the xorriso binary:
xorrisofs starts xorriso with -as mkisofs emulation already enabled
xorrecord starts xorriso with -as cdrecord emulation already enabled
osirrox starts with -osirrox image-to-disk copying already enabled
By default xorriso will depend on libreadline if the readline-dev headers
are present. This dependcy can be avoided by running
./configure --prefix=/usr --disable-libreadline
make clean ; make
Never omit the "make clean" command after switching libreadline enabling.
Other deliberate dependency reduction options of ./configure are:
--disable-libacl avoid use of ACL functions like acl_to_text()
--disable-xattr avoid use of xattr functions like listxattr()
--disable-zlib avoid use of zlib functions like compress2()
xorriso allows to use external processes as file content filters. This is
a potential security risk which may be avoided by ./configure option
--disable-external-filters
By default the filter feature is disabled if effective user id and real
user id differ. This ban can be lifted by
--enable-external-filters-setuid
In some situations Linux may deliver a better write performance to DVD drives
if 64 KB rather than 32 KB are transmitted in each write operation.
64k can be made default at configure time by:
--enable-dvd-obs-64k
xorriso C language API
Actually the dynamically linked xorriso binary is only a small start program
for the xorriso API that is implemented inside libisoburn.
There are API calls for command readers and interpreters, and there are
API calls for each single command of xorriso.
Interested programmers should have a look into the API definition at
xorriso/xorriso.h
and the start program
xorriso/xorriso_main.c
The header file xorriso.h gets installed suitable for
#include <libisoburn/xorriso.h>
So after installation of a binary libisoburn package you may find it e.g. as
/usr/local/include/libisoburn/xorriso.h
Drives and Disk File Objects
The user of libisoburn applications needs rw-permission for the CD/DVD/BD
drives which shall be used, even if only reading is intended.
A list of rw-accessible drives can be obtained by
xorriso -devices
resp. by xorriso API call
Xorriso_option_devices()
resp. by libburn API call
burn_drive_scan()
A possible source of problems are hald or other automounters.
If you can spot a process "hald-addon-storage" with the address of
your desired drive, then consider to kill it.
If you cannot get rid of the automounter that easily, try whether it helps
to always load the drive tray manually before starting a write run of
xorriso. Wait until the drive light is off.
Better try to unmount an eventually mounted media before a write run.
Besides true optical drives, libisoburn can also address disk files as input or
output drives. The addresses of the disk files have to be preceded by "stdio:".
Like:
"stdio:/tmp/pseudo_drive"
Note: xorriso by default prefixes "stdio:" to addresses outside the /dev tree
if they do not lead to an optical drive device file.
Testing
We are quite sure that libisofs produces accurate representations of the disk
files. This opinion is founded on a lot of test burns and checks by a little
test program which compares files from the mounted image with the orignals
on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff.
This program is not installed systemwide but stays in the installation
directory of the libisoburn tarball as test/compare_file . Usually it is
run as -exec payload of a find command. It demands at least three arguments:
The path of the file to compare, the prefix1 to be cut off from path
and the prefix2 which gets prepended afterwards to obtain the path of the
second file to compare.
As further argument there can be -no_ctime which suppresses the comparison
of ctime date stamps.
The exit value is 0 if no difference was detected, non-0 else.
Example: After
xorriso ... -pathspecs on -add /=/original/dir --
mount /media/dvd
cd test
compare tree /media/dvd with tree /original/dir :
find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \
| less
and vice versa:
find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \
| less

/**
@author Mario Danic, Vreixo Formoso, Thomas Schmitt
@mainpage Libisoburn Documentation Index
@section intro Introduction
Libburnia is an open-source project for reading, mastering and writing
optical discs. This page is about its capability to read, manipulate, and
write ISO 9660 filesystems with Rock Ridge extensions. Media can be optical
media or filesystem objects.
Our scope is currently Linux 2.4 and 2.6, or FreeBSD .
libisoburn is an add-on to libburn and libisofs which coordinates both and
also allows to grow ISO-9660 filesystem images on multi-session media as well
as on overwriteable media via the same API.
All media peculiarities are handled automatically.
xorriso is an application of all three libraries which creates, loads,
manipulates and writes ISO 9660 filesystem images with Rock Ridge extensions.
Manipulation is not only adding or overwriting of files but also deletion,
renaming, and attribute changing. An incremental backup feature is provided.
See xorriso/README for more
SONAME:
libisoburn.so.1 (since 0.1.0, February 2008).
@section using Using the libraries
Our build system is based on autotools.
User experience tells us that you will need at least autotools version 1.7.
To build libisoburn go into its toplevel directory and execute
- ./bootstrap (needed if you downloaded from SVN)
- ./configure
- make
To make the libraries accessible for running resp. developing applications
- make install
Read libisoburn/libisoburn.h for a description of the API.
See also README, xorriso/README, and the man page xorriso/xorriso.1 which
gives an idea of the capabilities provided by Libburnia.
You will also have to install and understand the two libraries of the
Libburnia project which provide fundamental services:
libburn is the library by which preformatted data get onto optical media.
See libburn/libburn.h for its API description.
libisofs is the library to handle ISO 9660 filesystems with Rock Ridge
extensions. Its API is described in libisofs/libisofs.h .

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

------------------------------------------------------------------------------
Contribution of libburnia-project.org to the GNU Operating System
------------------------------------------------------------------------------
GNU xorriso. By Thomas Schmitt <scdbackup@gmx.net>
Derived from and supported by libburnia-project.org, published via:
http://www.gnu.org/software/xorriso/xorriso_eng.html
ftp://ftp.gnu.org/gnu/xorriso/xorriso-0.5.7.tar.gz
Provided under GPL version 3 or later. No warranty.
------------------------------------------------------------------------------
xorriso is a program which copies file objects from POSIX compliant
filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows
session-wise manipulation of such filesystems. It can load the management
information of existing ISO images and it writes the session results to
optical media or to filesystem objects.
Vice versa xorriso is able to restore file objects from ISO 9660 filesystems.
A special property of xorriso is that it needs neither an external ISO 9660
formatter program nor an external burn program for CD or DVD but rather
incorporates the libraries of libburnia-project.org .
Currently it is fully supported on GNU/Linux with kernels >= 2.4,
on FreeBSD with ATAPI/CAM support enabled in the kernel, see atapicam(4),
and on OpenSolaris (tested with kernel 5.11).
On other X/Open compliant systems there will only be POSIX i/o with disk
file objects, but no direct MMC operation on CD/DVD/BD drives.
By using this software you agree to the disclaimer at the end of this text:
"... without even the implied warranty ..."
Compilation, First Glimpse, Installation
The most simple way to get xorriso from source code is the GNU xorriso tarball.
Prerequisites:
The tarball contains everything that is needed except the following system
components:
libc, libpthread
plus on FreeBSD: libiconv, libcam, IDE and SATA drives need atapicam
Optional at compile time are:
libreadline and the readline-dev headers make dialog mode more convenient.
zlib and zlib-devel allow zisofs compression.
on GNU/Linux: libacl and libacl-devel allow getting and setting ACLs.
If they were present at compile time, then the optional libraries have to
be present at runtime, too.
Obtain xorriso-0.5.7.tar.gz, take it to a directory of your choice and do:
tar xzf xorriso-0.5.7.tar.gz
cd xorriso-0.5.7
Within that directory execute:
./configure --prefix=/usr
make
This will produce a binary named
./xorriso/xorriso
If you want xorriso to report a "Build timestamp" with its option -version :
make buildstamped
You may strip the binary to reduce it in size
strip ./xorriso/xorriso
You may copy or move it to a directory where it can be found by the shell,
or you may execute xorriso at the place where it was built,
or you may execute as superuser:
make install
For general concepts, options and usage examples see
info xorriso
or
man 1 xorriso
The documents are part of the tarball as
xorriso/xorriso.info
xorriso/xorriso.1
Original source text of both is
xorriso/xorriso.texi
You may get a first glimpse by
info ./xorriso/xorriso.info
man ./xorriso/xorriso.1
The installation creates several alias links pointing to the xorriso binary:
xorrisofs starts xorriso with -as mkisofs emulation already enabled
xorrecord starts xorriso with -as cdrecord emulation already enabled
osirrox starts with -osirrox image-to-disk copying already enabled
If you want to avoid dependecy on libreadline although the libreadline
development package is installed, then rather build xorriso by:
./configure --prefix=/usr --disable-libreadline
make clean ; make
Never omit the "make clean" command after switching libreadline enabling.
Other deliberate dependency reduction options of ./configure are:
--disable-libacl avoid use of ACL functions like acl_to_text()
--disable-xattr avoid use of xattr functions like listxattr()
--disable-zlib avoid use of zlib functions like compress2()
xorriso brings own system adapters which allow burning optical media on
GNU/Linux and FreeBSD. Alternatively it can use libcdio-0.83 or later for
sending commands to optical drives:
--enable-libcdio
xorriso allows to use external processes as file content filters. This is
a potential security risk which may be avoided by ./configure option
--disable-external-filters
By default the filter feature is disabled if effective user id and real
user id differ. This ban can be lifted by
--enable-external-filters-setuid
Sometimes xorriso will yield better write performance on GNU/Linux if 64 KB are
transmitted in each write operation rather than 32 KB. See option -dvd_obs .
64k can be made default at configure time by:
--enable-dvd-obs-64k
For xorriso -as cdrecord emulation only:
In some situations GNU/Linux may deliver a better write performance to drives
if the track input is read with O_DIRECT (see man 2 open). The included libburn
and the cdrecord emulation of xorriso can be told to use this peculiar read
mode by:
--enable-track-src-odirect
Drives and Disk File Objects
The user of libisoburn applications needs rw-permission for the CD/DVD/BD
drives which shall be used, even if only reading is intended.
A list of rw-accessible drives can be obtained by
xorriso -devices
CD devices which offer not enough permission are invisible to normal users.
The superuser should be able to see any usable drive and then set the
permissions as needed.
On Linux and FreeBSD, rw-permissions are needed.
On Solaris, the privilege "sys_devices" and r-permission are needed.
The output of xorriso -devices might look like
0 -dev '/dev/sr0' rwrw-- : 'TSSTcorp' 'CDDVDW SH-S203B'
1 -dev '/dev/hda' rwrw-- : 'HL-DT-ST' 'DVD-ROM GDR8162B'
On Linux, full and insecure enabling of both for everybody would look like
chmod a+rw /dev/sr0 /dev/hda
This is equivalent to the traditional setup chmod a+x,u+s cdrecord.
On FreeBSD, device permissions are to be set in /etc/devfs.rules.
On Solaris, pfexec privileges may be restricted to "base,sys_devices".
See below "System Dependend Drive Permission Examples".
I strongly discourage to run xorriso with setuid root or via sudo !
It is not checked for the necessary degree of hacker safety.
Better consider to grant the necessary permissions to group "floppy"
and to add users to it.
A possible source of problems are hald or other automounters.
If you can spot a process "hald-addon-storage" with the address of
your desired drive, then consider to kill it.
If you cannot get rid of the automounter that easily, try whether it helps
to always load the drive tray manually before starting a write run of
xorriso. Wait until the drive light is off.
Better try to unmount an eventually mounted media before a write run.
Besides true optical drives, xorriso can also address disk files as input or
output drives. By default paths to files under /dev are accepted only if the
device represents a real optical drive. Other device files may be addressed
by prepending "stdio:" to the path.
Like:
xorriso -dev stdio:/dev/sdb ...more arguments...
This rule may be changed by xorriso option -drive_class.
Prefix "mmc:" causes a path to be accepted only if it is a real optical drive
which is accessible by generic SCSI/MMC commands.
Testing
We are quite sure that libisofs produces accurate representations of the disk
files. This opinion is founded on a lot of test burns and checks by a little
test program which compares files from the mounted image with the orignals
on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff.
This program is not installed systemwide but stays in the installation
directory of the xorriso tarball as test/compare_file . Usually it is
run as -exec payload of a find command. It demands at least three arguments:
The path of the first file to compare, the prefix1 to be cut off from path
and the prefix2 which gets prepended afterwards to obtain the path of the
second file to compare.
As further argument there can be -no_ctime which suppresses the comparison
of ctime date stamps.
The exit value is 0 if no difference was detected, non-0 else.
Example: After
xorriso ... -pathspecs on -add /=/original/dir -- -commit_eject all
mount /media/dvd
cd test
compare tree /media/dvd with tree /original/dir :
find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \
| less
and vice versa:
find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \
| less
File Formats
Sector Maps
Sector maps describe the valid and invalid blocks on a media or a disk copy of
a media. xorriso creates and reads these file with its option -check_media.
The file begins with 32 bytes of cleartext of which the last one is a
newline character. The first 25 say "xorriso sector bitmap v2 ", the
remaining six characters give the size of the info text as decimal number.
This number of bytes follows the first 32 and will not be interpreted
by xorriso. They are rather to inform a human reader about the media type
and its track layout.
After the info text there are two 4 byte signed integers, most significant
byte first. The first one, N, gives the number of bits in the following bitmap
and the second number S gives the number of 2 KiB blocks governed by a single
bit in the map. Then come the bits in form of 8-bit bytes.
Data block M is covered by bit B=M/S in the map, bit number B is stored in
byte B/8 as bit B%8. A valid readable data block has its bit set to 1.
Checksum Tags
Checksum tags are data blocks inside an ISO 9660 image which do not belong to
any file but rather tell the MD5 of a certain range of data blocks.
The superblock checksum tag is written after the ECMA-119 volume descriptors.
The tree checksum tag is written after the ECMA-119 directory entries.
The session checksum tag is written after all payload including the checksum
array. (Then follows eventual padding.)
The tags are single lines of printable text, padded by 0 bytes. They have
the following format:
Tag_id pos=# range_start=# range_size=# [session_start|next=#] md5=# self=#\n
Parameters md5= and self= are 32 digit hex, the others are decimal numbers.
Tag_id distinguishes the following tag types
"libisofs_rlsb32_checksum_tag_v1" Relocated 64 kB superblock tag
"libisofs_sb_checksum_tag_v1" Superblock tag
"libisofs_tree_checksum_tag_v1" Directory tree tag
"libisofs_checksum_tag_v1" Session end tag
A relocated superblock may appear at LBA 0 of an image which was produced for
being stored in a disk file or on overwriteable media (e.g. DVD+R, BD-RE).
xorriso records the first session at LBA 32. An eventual follow-up session
begins at the next block address which is divisible by 32 and higher than the
address of the previous session's end tag. Normally no session starts after the
address given by relocated superblock parameter session_start=.
Session oriented media like CD-R[W], DVD+R, BD-R will have no relocated
superblock but rather bear a table-of-content on media level.
A tag is valid if pos= tells its own block address and self= tells its own MD5
up to the last hex digit of md5=. range_start= tells the first block that is
covered by md5=, range_size= tells the number of blocks covered by md5=.
Relocated superblocks tell the block address of their session by session_start=.
Superblock and tree tag tell the block address of the next tag by next=.
The newline character at the end is mandatory.
libisoburn
xorriso is based on libisofs which does ISO 9600 filesystem aspects and on
libburn which does the input and output aspects. Parts of this foundation
are accessed via libisoburn, which is closely related to xorriso.
libisoburn provides two services:
- Encapsulation of coordination between libisofs and libburn.
- Emulation of ISO 9660 multi-session on overwriteable media
or random access files.
The sourcecode of all three libraries is included in the xorriso standalone
tarball. It is compiled with xorriso and linked statically.
But you may as well get and install releases of libburn and libisofs, in order
to be able to install a release of libisoburn which produces libisoburn.so.1
and a matching dynamically linked xorriso binary.
This binary is leaner but depends on properly installed libraries of suitable
revision.
Dynamic library and compile time header requirements for libisoburn-0.5.6 :
- libburn.so.4 , version libburn-0.7.8 or higher
- libisofs.so.6 , version libisofs-0.6.32 or higher
libisoburn and xorriso will not start with libraries which are older than their
headers seen at compile time. So compile in the oldest possible installation
setup unless you have reason to enforce a newer bug fix level.
GNU xorriso has less runtime dependencies and can be moved more freely.
System Dependend Drive Permission Examples
Accessing the optical drives requires privileges which usually are granted
only to the superuser. GNU/Linux, FreeBSD and Solaris offer quite different
approaches for avoiding the need for unrestricted privileges.
First check whether some friendly system setting already allows you to
access the drives as normal user:
xorriso -devices
Those drives of which you see address and type strings are already usable.
If there remain drives invisible which the superuser can see by the same
command, then the following examples might help:
---------------------
On all three systems:
---------------------
Add the authorized users of CD drives to group "floppy" in /etc/group.
If missing: create this group.
Changes to /etc/group often only affect new login sessions. So log out and in
before making the first tests.
-------------
On GNU/Linux:
-------------
Allow rw-access to the drives
chgrp floppy /dev/sr0 /dev/sr1
chmod g+rw /dev/sr0 /dev/sr1
It might be necessary to perform chgrp and chmod after each reboot or to
edit distro dependent device configuration files for permanent settings.
-----------
On FreeBSD:
-----------
Edit /etc/devfs.rules and make sure to have these lines
[localrules=10]
add path 'acd*' mode 0664 group floppy
add path 'cd*' mode 0664 group floppy
add path 'pass*' mode 0664 group floppy
add path 'xpt*' mode 0664 group floppy
[localrules=5]
add path 'pass*' mode 0664 group floppy
add path 'cd*' mode 0664 group floppy
add path 'xpt*' mode 0664 group floppy
add path 'acd*' mode 0664 group floppy
Edit /etc/rc.conf and add the following line if missing
devfs_system_ruleset="localrules"
This gets into effect by reboot or by command
/etc/rc.d/devfs start
-----------
On Solaris:
-----------
Run xorriso by
pfexec xorriso ...arguments...
The following settings will make pfexec keep original UID and EUID and prevent
most superuser powers. Be aware that you still can manipulate all device files
if you have the file permissions for that.
Full root privileges for xorriso can then be aquired only by command su.
Edit /etc/security/exec_attr and add this line to the other "Media Backup"
lines:
Media Backup:solaris:cmd:::/usr/local/bin/xorriso:privs=basic,sys_devices
Edit /etc/user_attr and add profile "Media Backup" to the user's line:
thomas::::profiles=Media Backup,Primary Administrator;roles=root
See also man privileges, man exec_attr, man user_attr.
Then allow the group r-access to the drives
pfexec chgrp floppy /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
pfexec chmod g+r /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
The last two commands have to be executed after each boot. I do not know
the relevant device configuration files yet.

# Not intended for general use in production installations !
#
# This is a development tool which expects a special setup of directories.
# It is to be executed in a common parent of the directories
# nglibisofs-develop libburn-develop libisoburn-develop
# where tarballs or repository copies have been installed of
# libisofs libburn libisoburn
# obtained according to instructions on http://libburnia-project.org.
#
# It creates a new directory tree
# xorriso-standalone
# for building GNU xorriso.
#
# The ./bootstrap script gets applied and a source tarball
# is made.
#
# From that tree can be build a binary xorriso/xorriso which at runtime
# does not depend on installed libburnia libraries.
# Execute in xorriso-standalone :
#
# ./configure && make
#
# By the variable setting create_gnu_xorriso="yes"
# the result will become a GNU xorriso tarball under GPLv3+.
# Without this setting, the result is technically equivalent but
# stays under GPLv2+. In that case the files xorriso/*_gnu_xorriso
# are merely informative.
# Note that it is not permissible to revert the transition from
# GPLv2+ to GPLv3+. (Rather derive a new GPLv2+ from libburnia.)

<P>
<H1>GNU xorriso</H1>
<H2>ISO 9660 Rock Ridge Filesystem Manipulator for GNU/Linux and FreeBSD</H2>
</P>
</CENTER>
<P>
<H2>Purpose:</H2>
xorriso copies file objects from POSIX compliant filesystems
into Rock Ridge enhanced ISO 9660 filesystems and allows
session-wise manipulation of such filesystems. It can load the management
information of existing ISO images and it writes the session results to
optical media or to filesystem objects.
<BR>
Vice versa xorriso is able to copy file objects out of ISO 9660 filesystems.
</P>
<P>
<HR>
<A HREF="#download">Direct hop to download links -></A>
<P>
<H2>Hardware requirements:</H2>
About any CD, DVD, or BD recorder produced in the recent ten years.
<BR>
<A HREF="http://libburnia-project.org">libburn</A>
supports recorders which are compliant to standards MMC-1 for CD and
MMC-5 for DVD or BD.
<BR>
GNU/Linux and FreeBSD allow to access drives connected
via SCSI, PATA (aka IDE, ATA), USB, or SATA.
<BR>
xorriso also operates on ISO images in data files or block devices.
Images or add-on sessions may be written to about any kind of file object.
</P>
<P>
<H2>Software requirements :</H2>
<DL>
<DT>GNU/Linux with kernel 2.4 or higher, libc, libpthread :</DT>
<DD>With kernel 2.4 a PATA/IDE drive has to be under ide-scsi emulation.</DD>
<DD>With kernel 2.6 ide-scsi is not needed.</DD>
<DT>or FreeBSD, libc, libpthread :</DT>
<DD>PATA/IDE drives need atapicam running.</DD>
<DD>SATA drives need atapicam or ahci running.</DD>
<DD>libcam has to be installed.</DD>
<DD>libiconv has to be installed.</DD>
<DT>or some other X/Open system, libc, libpthread :</DT>
<DD>
There will be no direct operation of optical drives, but only POSIX i/o
with objects of the local filesystem.
</DD>
<DD>
Might work with DVD-RAM, DVD+RW, BD-RE
but rather not with CD, DVD-R, DVD+R, BD-R.
</DD>
</DL>
<H3>Optional supporting software:</H2>
<DL>
<DT>libreadline and libreadline-dev</DT>
<DD>eventually make dialog more convenient.</DD>
<DT>libacl and libacl-devel</DT>
<DD>eventually allow on GNU/Linux to get and set ACLs.</DD>
<DT>zlib and zlib-devel</DT>
<DD>eventually allow zisofs and gzip compression.</DD>
</DL>
</P>
<P>
This program has been tested on GNU/Linux, FreeBSD, and Solaris systems.<BR>

Operates on an existing ISO image or creates a new one.
</LI>
<LI>
Copies files from filesystem into the ISO image and vice versa.
</LI>
<LI>
Changes file properties, renames or deletes file objects in the ISO image.
</LI>
<LI>
Updates ISO subtrees incrementally to match given disk subtrees.
</LI>
<LI>
Can record and restore hard link relations, ACL, and xattr.
</LI>
<LI>
Can attach MD5 checksums to each data file and the whole session.
</LI>
<LI>
File content may get zisofs or gzip compressed or filtered by external
processes.
</LI>
<LI>
Writes result as completely new image or as add-on session
to optical media or filesystem objects.
</LI>
<LI>
Can activate ISOLINUX and GRUB boot images by El Torito boot record and MBR.
</LI>
<LI>
Can perform multi-session tasks as emulation of mkisofs and cdrecord.
</LI>
<LI>
Can issue commands to mount older sessions on GNU/Linux or FreeBSD.
</LI>
<LI>
Can check media for damages and copy readable blocks to disk.
</LI>
<LI>
Scans for optical drives, blanks re-useable optical media, formats media.
</LI>
<LI>

It can be run on blank media to create a copy of the mentioned disk

Older states can be retrieved by help of mount options like "sbsector="

Operating systems usually mount the most recent session on media.
xorriso can issue the appropriate mount commands for older sessions.
First get an overview of the sessions on the media:
</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /dev/sr0 -toc</KBD></DD>
<PRE>
TOC layout : Idx , sbsector , Size , Volume Id
ISO session : 1 , 0 , 104719s , PROJECTS_MAIL_2008_08_10_231435
ISO session : 2 , 106928 , 6785s , PROJECTS_MAIL_2008_08_14_184548
...
ISO session : 76 , 820384 , 11035s , PROJECTS_MAIL_2009_01_04_191150
</PRE>
<DT>
Then become superuser and let xorriso mount the session of August 14, 2008
to directory /mnt:
</DT>
<DD>#<KBD>
&nbsp;xorriso -osirrox on -mount /dev/sr0 volid '*_2008_08_14_*' /mnt
</KBD></DD>
<DT>
To be later unmounted by: <KBD>umount /mnt</KBD>
</DT>
<DT>
<HR>
</DT>
<DT>
After the user has already created a suitable file tree on disk
and copied the ISOLINUX files into subdirectory ./boot/isolinux of
that tree, xorriso can burn an El Torito bootable media:
</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /dev/sr0 -blank as_needed \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -map /home/me/ISOLINUX_prepared_tree / \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -boot_image isolinux dir=/boot/isolinux</KBD></DD>
<DT>
An additional MBR is generated if the file isolinux.bin is modern enough
(syslinux version 3.72) and ready for "isohybrid". An MBR enables booting
from hard disk or USB stick.
<HR>
</DT>
<DT>ISO images may not only be stored on optical media but also in
regular disk files or block devices for full multi-session operation.
</DT>
<DD>$<KBD>&nbsp;xorriso -dev /tmp/regular_file ...other.options...</DD>
<DT>
A default setting for safety reasons requires that files below /dev/
need prefix &quot;stdio:&quot; if they do not lead to MMC burner devices.
Be cautious not to overwrite your hard disk instead of your USB stick:
</DT>
<DD>$<KBD>&nbsp;xorriso -dev stdio:/dev/sdb ...other.options...</DD>
<DT>Other file types are suitable only for writing but not for reading:</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /tmp/named_pipe ...other.options...</DD>
<DT>In batch mode it is possible to operate xorriso in a pipeline
with an external consumer of the generated ISO image. Any message
output will be redirected to stderr in this case.
Examples for consumers are cdrecord or growisofs on operating systems
where xorriso cannot operate the burner drive directly,
or a ssh pipe to another system which has the desired drive
and a suitable burn program.</DT>
<DD>$<KBD>&nbsp;xorriso -outdev - ...other.options... | consumer</KBD></DD>
<DT>
<HR>
</DT>
<DT>
Let xorriso serve underneath growisofs via its alias name "xorrisofs"
which enables mkisofs emulation:
</DT>
<DD>$<KBD>&nbsp;export MKISOFS="xorrisofs"</KBD></DD>
<DD>$<KBD>&nbsp;growisofs -Z /dev/dvd /some/files</KBD></DD>
<DD>$<KBD>&nbsp;growisofs -M /dev/dvd /more/files</KBD></DD>
<DT>
One may switch from mkisofs emulation to xorriso's own command mode:
</DT>
<DD>$<KBD>&nbsp;growisofs -M /dev/dvd -- outdev - -update_r /my/files /files
</KBD></DD>
<DT>
<HR>
</DT>
<DT>If for any reason the reading operating system mishandles the ISO image
or some files in it, one may enable reverse operation of xorriso and copy
files or trees to disk:
<DD>$<KBD>&nbsp;xorriso -acl on -xattr on \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -indev /dev/sr0 \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -osirrox on \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -cpx '/pictures/private/horses*/*buttercup*' \</KBD></DD>
<DD><KBD>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /home/her/buttercup_dir -- \</KBD>
<DD><KBD>&nbsp;&nbsp; -extract /sounds /home/her/sounds_from_me</KBD></DD>
</DD>
<DT>Consider to enter dialog mode and use commands like
<KBD>-cd , -du , -lsl , -find<KBD>.

/* xorriso - Command line oriented batch and dialog tool which creates, loads,
manipulates and burns ISO 9660 filesystem images.
Copyright 2007-2010 Thomas Schmitt, <scdbackup@gmx.net>
Initial code of this program was derived from program src/askme.c out
of scdbackup-0.8.8, Copyright 2007 Thomas Schmitt, BSD-License.
Provided under GPL version 2 or later, with the announcement that this
might get changed in future. I would prefer BSD or LGPL as soon as the
license situation of the library code allows that.
(This announcement affects only future releases of xorriso and it will
always be possible to derive a GPLv2+ from the future license.)
There is a derived package "GNU xorriso" under GPLv3+ which combines the
libburnia libraries and program xorriso to a statically linked binary.
Overview of xorriso architecture:
libburn provides the ability to read and write data.
libisofs interprets and manipulates ISO 9660 directory trees. It generates
the output stream which is handed over to libburn.
libisoburn by its lower level API encapsulates the connectivity issues
between libburn and libisofs. This API also enables multi-session emulation
on overwritable media and random access file objects.
xorriso is the higher level API of libisoburn which allows to operate all
three libraries by a unified set of commands.
xorriso.h exposes the public functions.
Among these functions are direct equivalents of the xorriso interpreter
commands. There are also functions for fundamental management and for
handling event messages.
This file xorriso_main.c runs the xorriso API as batch and dialog program.
One should not mix the use of the xorriso API with the use of the lower
level APIs of libburn, libisofs, libisoburn.
The xorriso source is divided in two groups:
A set of source modules interacts with the libraries:
base_obj.[ch] fundamental operations of the XorrisO object
lib_mgt.[ch] manages the relation between xorriso and the libraries
drive_mgt.[ch] operates on drives and media
iso_img.[ch] operates on ISO images and their global properties
iso_tree.[ch] access nodes of the libisofs tree model
iso_manip.[ch] manipulates the libisofs tree model
sort_cmp.[ch] sorts and compare tree nodes
write_run.[ch] functions to write sessions
read_run.[ch] functions to read data from ISO image
filters.[ch] operates on data filter objects
xorrisoburn.h declarations needed by the non-library modules
Another set is independent of the liburnia libraries:
parse_exec.c deals with parsing and interpretation of command input
sfile.c functions around files and strings
aux_objects.c various helper classes
misc_funct.c miscellaneous helper functions
findjob.c performs tree searches in libisofs or in POSIX filesystem
check_media.c perform verifying runs on media resp. images
text_io.c text i/o functions
match.c functions for pattern matching
emulators.c emulators for mkisofs and cdrecord
disk_ops.c actions on onjects of disk filesystems
cmp_update.c compare or update files between disk filesystem and
ISO filesystem
opts_a_c.c options -a* to -c*
opts_d_h.c options -d* to -h*
opts_i_o.c options -i* to -o*
opts_p_z.c options -p* to -z*
xorriso_private.h contains the definition of struct Xorriso and for
convenience includes the .h files of the non-library group.

It gets compared against the version macros in xorriso.h :
Xorriso_header_version_majoR
Xorriso_header_version_minoR
Xorriso_header_version_micrO
If the header is too old then the following code shall cause failure of
cdrskin compilation rather than to allow production of a program with
unpredictable bugs or memory corruption.
The compiler messages supposed to appear in this case are:
error: 'XORRISO_MISCONFIGURATION' undeclared (first use in this function)
error: 'INTENTIONAL_ABORT_OF_COMPILATION__HEADERFILE_xorriso_dot_h_TOO_OLD__SEE_xorriso_main_dot_c' undeclared (first use in this function)
