@section intro Introduction
|
|
|
|
Libburn is an open-source library for reading, mastering and writing
|
|
optical discs. For now this means only CD-R and CD-RW.
|
|
|
|
The project comprises of several more or less interdependent parts which
|
|
together strive to be a usable foundation for application development.
|
|
These are libraries, language bindings, and middleware binaries which emulate
|
|
classical (and valuable) Linux tools.
|
|
|
|
Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
|
|
this for now, because of our history. The project could need advise from or
|
|
membership of skilled kernel people and people who know how to talk CD/DVD
|
|
drives into doing things.
|
|
|
|
We do have a workable code base for burning data CDs, though. The burn API is
|
|
quite comprehensively documented and can be used to build a presentable
|
|
application.
|
|
We do have a functional binary which emulates parts of cdrecord in order to
|
|
prove that usability, and in order to allow you to explore libburn's scope
|
|
by help of existing cdrecord frontends.
|
|
|
|
@subsection components The project components (list subject to growth, hopefully):
|
|
|
|
- libburn the library by which preformatted data get onto optical media.
|
|
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
|
|
/dev/hdX (e.g. on kernel 2.6).
|
|
libburn is the foundation of our cdrecord emulation.
|
|
|
|
- libisofs the library to pack up hard disk files and directories into a
|
|
ISO 9660 disk image. This may then be brought to CD via libburn.
|
|
libisofs is to be the foundation of our upcoming mkisofs emulation.
|
|
|
|
- cdrskin a limited cdrecord compatibility wrapper for libburn.
|
|
cdrecord is a powerful GPL'ed burn program included in Joerg
|
|
Schilling's cdrtools. cdrskin strives to be a second source for
|
|
the services traditionally provided by cdrecord.
|
|
cdrskin does not contain any bytes copied from cdrecord's sources.
|
|
Many bytes have been copied from the message output of cdrecord
|
|
runs, though.
|
|
See cdrskin/README for more.
|
|
|
|
- "test" is a collection of application gestures and examples given by the
|
|
authors of the library features. cdrskin for example originally
|
|
emerged from test/burniso.c and you can see traces of my first
|
|
steps in there. Explore these examples if you look for inspiration.
|
|
|
|
We plan to be a responsive upstream. Bear with us. We are still practicing.
|
|
Our build system is based on autotools.
|
|
User experience tells us that you will need at least autotools version 1.7.
|
|
|
|
To build libburn and its subprojects it should be sufficient to go into
|
|
its toplevel directory and execute
|
|
./bootstrap (needed if you downloaded from SVN and not a release tarball)
|
|
./configure
|
|
make
|
|
|
|
To make the libraries accessible for running resp. developing applications
|
|
make install
|
|
|
|
@section using Using the libraries
|
|
|
|
Both libraries are written in C language and get built by autotools.
|
|
Thus we expect them to be useable by a wide range of Linux-implemented
|
|
languages and development tools.
|
|
|
|
We are still practicing.
|
|
|
|
For the libburn library there is a reference and demo application
|
|
test/libburner
|
|
|
|
@subsection concepts Libburn library concepts
|
|
|
|
There are a few concepts to introduce in order for you to understand how to
|
|
use Libburn. So, lets start with them:
|
|
|
|
<ol>
|
|
<li> Read - The process of reading the data on a disc for storage or
|
|
copying.
|
|
<li> Write - The process of writing data onto a disc to create a new
|
|
disc image or append to an existing one.
|
|
<li> Drive - A Drive is a hardware device used to reading and/or writing
|
|
discs. CD burners and CD-ROMs are examples of Drives.
|
|
</ol>
|
|
|
|
@subsection working Working with the library
|
|
|
|
Now that you understand the above @ref concepts, you're ready to look at the
|
|
actual use of the library.
|
|
|
|
In general, using the library to perform a process consists of the following
|
|
steps:
|
|
|
|
<ol>
|
|
<li> Initialize the library.
|
|
<li> Depends on wether you know the persisten drive address in advance
|
|
If yes:
|
|
2a. Aquire this drive alone and directly by function
|
|
burn_drive_scan_and_grab() and be done until step 5
|
|
If no address known yet:
|
|
2b. Scan for available Drives..
|
|
<li>b Choose a Drive for reading/writing and inquire its persistent address.
|
|
<li>b Shut down library, re-initialize it and like in step 2a aquire the
|
|
chosen drive by function burn_drive_scan_and_grab()
|
|
<li> Fill in the options for the operation.
|
|
<li> Wait for the operation to complete, displaying status along the wayi
|
|
if desired.
|
|
<li> Release the Drive.
|
|
<li> Destroy the library instance. (If you're done working with the library.)
|
|
</ol>
|
|
|
|
Here's a minimal demo application for the libburn library
|
|
|
|
@include libburner.c
