#define isoburn_igopt_omit_version_numbers 1 |
Relaxed constraints.
Setting any of the bits to 1 break the specifications, but it is supposed to work on most moderns systems. Use with caution.
o | The option set to work on | |
relax | Bitfield: bit0= omit_version_numbers Omit the version number (";1") at the end of the ISO-9660 identifiers. Version numbers are usually not used. bit1= allow_deep_paths Allow ISO-9660 directory hierarchy to be deeper than 8 levels. bit2= allow_longer_paths Allow path in the ISO-9660 tree to have more than 255 characters. bit3= max_37_char_filenames Allow a single file or directory hierarchy to have up to 37 characters. This is larger than the 31 characters allowed by ISO level 2, and the extra space is taken from the version number, so this also forces omit_version_numbers. bit4= no_force_dots ISO-9660 forces filenames to have a ".", that separates file name from extension. libisofs adds it if original filename has none. Set this to 1 to prevent this behavior. bit5= allow_lowercase Allow lowercase characters in ISO-9660 filenames. By default, only uppercase characters, numbers and a few other characters are allowed. bit6= allow_full_ascii Allow all ASCII characters to be appear on an ISO-9660 filename. Note * that "/" and "\0" characters are never allowed, even in RR names. bit7= joliet_longer_paths Allow paths in the Joliet tree to have more than 240 characters. bit8= always_gmt Write timestamps as GMT although the specs prescribe local time with eventual non-zero timezone offset. Negative timezones (west of GMT) can trigger bugs in some operating systems which typically appear in mounted ISO images as if the timezone shift from GMT was applied twice (e.g. in New York 22:36 becomes 17:36). bit9= rrip_version_1_10 Write Rock Ridge info as of specification RRIP-1.10 rather than RRIP-1.12: signature "RRIP_1991A" rather than "IEEE_1282", field PX without file serial number. bit10= dir_rec_mtime Store as ECMA-119 Directory Record timestamp the mtime of the source rather than the image creation time. bit11= aaip_susp_1_10 Write AAIP fields without announcing AAIP by an ER field and without distinguishing RRIP fields from the AAIP field by prefixed ES fields. This saves 5 to 10 bytes per file and might avoid problems with readers which only accept RRIP. SUSP-1.10 allows it, SUSP-1.12 frowns on it. |

#define isoburn_igopt_rockridge 1 |
Which extensions to support.
o | The option set to work on | |
ext | Bitfield: bit0= rockridge Rock Ridge extensions add POSIX file attributes like owner, group, access permissions, long filenames. Very advisable if the designed audience has Unix style systems. bit1= joliet Longer filenames for Windows systems. Weaker than RockRidge, but also readable with Linux. bit2= iso1999 This is rather exotic. Better do not surprise the readers. bit3= hardlinks Enable hardlink consolidation. IsoNodes which refer to the same source object and have the same properties will get the same ISO image inode numbers. If combined with isoburn_igopt_rrip_version_1_10 below, then the PX entry layout of RRIP-1.12 will be used within RRIP-1.10 (mkisofs does this without causing visible trouble). bit5= aaip The libisofs specific SUSP based extension of ECMA-119 which can encode ACL and XFS-style Extended Attributes. bit6= session_md5 |

int isoburn_activate_session | ( | struct burn_drive * | d | ) |
Call this after isoburn_disc_write has finished and burn_drive_wrote_well() indicates success.
It will eventually complete the emulation of multi-session functionality, if needed at all. Let libisoburn decide. Not a wrapper, but peculiar to libisoburn.

int isoburn_attach_image | ( | struct burn_drive * | d, | |

Set the IsoImage to be used with a drive.
This eventually releases the reference to the old IsoImage attached to the drive. Caution: Use with care. It hardly makes sense to replace an image that reflects a valid ISO image on media. This call is rather intended for writing a newly created and populated image to blank media. The use case in xorriso is to let an image survive the change or demise of the outdev target drive.
d | The drive which shall be write target of the volset. | |
image | The image that represents the image to be written. This image pointer MUST already be a valid reference suitable for iso_image_unref(). It may have been obtained by appropriate libisofs calls or by isoburn_read_image() with d==NULL. |

Overview.
libisoburn is a frontend for libraries libburn and libisofs which enables creation and expansion of ISO-9660 filesystems on all CD/DVD 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.
Connector functions
libisofs and libburn do not depend on each other but share some interfaces by which they can cooperate. libisoburn establishes the connection between both modules by creating the necessary interface objects and attaching them to the right places.
Wrapper functions
The priciple of this frontend is that you may use any call of libisofs or libburn unless it has a isoburn_*() wrapper listed in the following function documentation.
E.g. call isoburn_initialize() rather than iso_init(); burn_initialize(); and call isoburn_drive_scan_and_grab() rather than burn_drive_scan_and_grab(). But you may call burn_disc_get_profile() directly if you want to display the media type.
The wrappers will transparently provide the necessary emulations which are appropriate for particular target drives and media states. To learn about them you have to read both API descriptions: the one of the wrapper and the one of the underlying libburn or libisofs call.
Macros BURN_* and functions burn_*() are documented in <libburn/libburn.h> Macros ISO_* and functions iso_*() are documented in <libisofs/libisofs.h>
Usage model
There may be an input drive and an output drive. Either of them may be missing with the consequence that no reading resp. writing is possible. Both drive roles can be fulfilled by the same drive.
Input can be a random access readable libburn drive: optical media, regular files, block devices. Output can be any writeable libburn drive: writeable optical media in burner, writeable file objects (no directories).
libburn demands rw-permissions to drive device file resp. file object.
If the input drive provides a suitable ISO RockRidge image, then its tree may be loaded into memory and can then be manipulated by libisofs API calls. The loading is done by isoburn_read_image() under control of struct isoburn_read_opts which the application obtains from libisoburn and manipulates by the family of isoburn_ropt_set_*() functions.
Writing of result images is controlled by libisofs related parameters in a struct isoburn_imgen_opts which the application obtains from libisoburn and manipulates by the family of isoburn_igopt_set_*() functions.
All multi-session aspects are handled by libisoburn according to these settings. The application does not have to analyze media state and write job parameters. It rather states its desires which libisoburn tries to fulfill, or else will refuse to start the write run.
Setup for Growing, Modifying or Blind Growing
The connector function family offers alternative API calls for performing the setup for several alternative image generation strategies.
Growing: If input and output drive are the same, then isoburn_prepare_disc() is to be used. It will lead to an add-on session on appendable or overwriteable media with existing ISO image. With blank media it will produce a first session.
Modifying: If the output drive is not the input drive, and if it bears blank media or overwriteable without a valid ISO image, then one may produce a consolidated image with old and new data. This will copy file data from an eventual input drive with valid image, add any newly introduced data from the local filesystem, and produce a first session on output media. To prepare for such an image generation run, use isoburn_prepare_new_image().
Blind Growing: This method reads the old image from one drive and writes the add-on session to a different drive. That output drive is nevertheless supposed to finally lead to the same media from where the session was loaded. Usually it will be stdio:/dev/fd/1 (i.e. stdout) being piped into some burn program like with this classic gesture: mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev Blind growing is prepared by the call isoburn_prepare_blind_grow(). The input drive should be released immediately after this call in order to allow the consumer of the output stream to access that drive for writing.
After either of these setups, some peripheral libburn drive parameter settings like burn_write_opts_set_simulate(), burn_write_opts_set_multi(), burn_drive_set_speed(), burn_write_opts_set_underrun_proof() should be made. Do not set the write mode. It will be chosen by libisoburn so it matches job and media state.
Writing the image
Then one may start image generation and write threads by isoburn_disc_write(). Progress may be watched at the output drive by burn_drive_get_status() and isoburn_get_fifo_status().
At some time, the output drive will be BURN_DRIVE_IDLE indicating that writing has ended. One should inquire isoburn_drive_wrote_well() to learn about overall success.
Finally one must call isoburn_activate_session() which will complete any eventual multi-session emulation.
Application Constraints
Applications shall include libisofs/libisofs.h , libburn/libburn.h and this file itself: libisoburn/libisoburn.h . They shall link with -lisofs -lburn -lisoburn or with the .o files emerging from building those libraries from their sources.
Applications must use 64 bit off_t, e.g. on 32-bit Linux by defining define _LARGEFILE_SOURCE define _FILE_OFFSET_BITS 64 or take special precautions to interface with the library by 64 bit integers where above .h files prescribe off_t. Not to use 64 bit file i/o will keep the application from producing and processing ISO images of more than 2 GB size. Initialize libisoburn, libisofs and libburn.

Check whether all features of header file libisoburn.h from the given major.minor.micro revision triple can be delivered by the library version which is performing this call.
An application of libisoburn can easily memorize the version of the libisofs.h header in its own code. Immediately after isoburn_initialize() it should simply do this check: if (! isoburn_is_compatible(isoburn_header_version_major, isoburn_header_version_minor, isoburn_header_version_micro, 0)) ...refuse to start the program with this dynamic library version...

To choose the expansion method of Blind Growing: Create a disc object for writing an add-on session from the created or loaded IsoImage which has been manipulated via libisofs, to a different drive than the one from where it was loaded.
Usually output will be stdio:/dev/fd/1 (i.e. stdout) being piped into some burn program like with this classic gesture: mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev Parameter translation into libisoburn: $dev is the address by which parameter in_drive of this call was aquired $msc1 was set by isoburn_set_msc1() before image reading or was detected from the in_drive media $nwa is a parameter of this call or can be used as detected from the in_drive media
This call waits for libisofs output to become available and then detaches the input drive object from the data source object by which libisofs was reading from the input drive. So, as far as libisofs is concerned, that drive may be released immediately after this call in order to allow the consumer to access the drive for writing. The consumer should wait for input to become available and only then open its burn drive. With cdrecord this is caused by option -waiti.
The resulting burn_disc object has to be disposed when all its writing is done and the drive is BURN_DRIVE_IDLE again after asynchronous burn_disc_write().
in_drive | The input drive,grabbed with isoburn_drive_scan_and_grab(). | |
disc | Returns the newly created burn_disc object. | |

To choose the expansion method of Modifying: Create a disc object for producing a new image from a previous image plus the changes made by user.
The generated burn_disc is suitable to be written to a grabbed drive with blank writeable media. But you must not use the same drive for input and output, because data will be read from the source drive while at the same time the target drive is already writing. The resulting burn_disc object has to be disposed when all its writing is done and the drive is BURN_DRIVE_IDLE again after asynchronous burn_disc_write().

Load the ISO filesystem directory tree from the media in the given drive.
This will give libisoburn the base on which it can let libisofs perform image growing or image modification. The loaded volset gets attached to the drive object and handed out to the application. Not a wrapper, but peculiar to libisoburn.
d | The drive which holds an existing ISO filesystem or blank media. d is allowed to be NULL which produces an empty ISO image. In this case one has to call before writing isoburn_attach_volset() with the volset from this call and with the intended output drive. | |
read_opts | The read options which can be chosen by the application | |
image | the image read, if the disc is blank it will have no files. This reference needs to be released via iso_image_unref() when it is not longer needed. The drive, if not NULL, will hold an own reference which it will release when it gets a new volset or when it gets released via isoburn_drive_release(). You can pass NULL if you already have a reference or you plan to obtain it later with isoburn_get_attached_image(). Of course, if you haven't specified a valid drive (i.e., if d == NULL), this parameter can't be NULL. |

Note: Above version numbers are also recorded in configure.ac because libtool wants them as parameters at build time.
For the library compatibility check, ISOBURN_*_VERSION in configure.ac are not decisive. Only the three numbers here do matter. Usage discussion:Some developers of the libburnia project have differing opinions how to ensure the compatibility of libaries and applications.
It is about whether to use at compile time and at runtime the version numbers isoburn_header_version_* provided here. Thomas Schmitt advises to use them. Vreixo Formoso advises to use other means.
At compile time:
Vreixo Formoso advises to leave proper version matching to properly programmed checks in the the application's build system, which will eventually refuse compilation.
Thomas Schmitt advises to use the macros defined here for comparison with the application's requirements of library revisions and to eventually break compilation.
Both advises are combinable. I.e. be master of your build system and have if checks in the source code of your application, nevertheless.
At runtime (via *_is_compatible()):
Vreixo Formoso advises to compare the application's requirements of library revisions with the runtime library. This is to allow runtime libraries which are young enough for the application but too old for the lib*.h files seen at compile time.
Thomas Schmitt advises to compare the header revisions defined here with the runtime library. This is to enforce a strictly monotonous chain of revisions from app to header to library, at the cost of excluding some older libraries.
These two advises are mutually exclusive.
-----------------------------------------------------
For an implementation of the Thomas Schmitt approach, see libisoburn/burn_wrap.c : isoburn_initialize() This connects libisoburn as "application" with libisofs as "library".
The compatible part of Vreixo Formoso's approach is implemented in configure.ac LIBBURN_REQUIRED, LIBISOFS_REQUIRED. In isoburn_initialize() it would rather test by iso_lib_is_compatible(isoburn_libisofs_req_major,... than by iso_lib_is_compatible(iso_lib_header_version_major,... and would leave out the ugly compile time traps. Announce to the library an application provided method for immediate delivery of messages. It is used when no drive is affected directly or if the drive has no own msgs_submit() method attached by isoburn_drive_set_msgs_submit. If no method is preset or if the method is set to NULL then libisoburn delivers its messages through the message queue of libburn.

Set a callback function for producing pacifier messages during the lengthy process of image reading.
The callback function and the application handle are stored until they are needed for the underlying call to libisofs. Other than with libisofs the handle is managed entirely by the application. An idle .free() function is exposed to libisofs. The handle has to stay valid until isoburn_read_image() is done. It has to be detached by isoburn_set_read_pacifier(drive, NULL, NULL); before it may be removed from memory.

Obtain eventual ISO image parameters of an emulated track.
This info was gained with much effort and thus gets cached in the track object. If this call returns 1 then one can save a call of isoburn_read_iso_head() with return mode 1 which could cause an expensive read operation.

void isoburn_version | ( | int * | major, | |
int * | minor, | |||
int * | micro | |||
) |
Obtain the three release version numbers of the library.
These are the numbers encountered by the application when linking with libisoburn, i.e. possibly not before run time. Better do not base the fundamental compatibility decision of an application on these numbers. For a reliable check use isoburn_is_compatible().
major | The maturity version (0 for now, as we are still learning) | |
minor | The development goal version. | |
micro | The development step version. This has an additional meaning: |
Pare numbers indicate a version with frozen API. I.e. you can rely on the same set of features to be present in all published releases with that major.minor.micro combination. Features of a pare release will stay available and ABI compatible as long as the SONAME of libisoburn stays "1". Currently there are no plans to ever change the SONAME.
Odd numbers indicate that API upgrades are in progress. I.e. new features might be already present or they might be still missing. Newly introduced features may be changed incompatibly or even be revoked before release of a pare version. So micro revisions {1,3,5,7,9} should never be used for dynamic linking unless the proper library match can be guaranteed by external circumstances.
