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.

Since:
0.1.0
Parameters:
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 and Joliet identifiers. Version numbers are usually not used by readers. 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. bit12= only_iso_numbers Same as bit1 omit_version_number but restricted to the names in the eventual Joliet tree.

0.5.4 For reasons of backward compatibility it is not possible yet to disable version numbers for ISO 9660 while enabling them for Joliet. bit13= no_j_force_dots Same as no_force_dots but affecting the names in the eventual Joliet tree rather than the ISO 9660 / ECMA-119 names.

0.5.4 Previous versions added dots to Joliet names unconditionally. bit14= allow_dir_id_ext Convert directory names for ECMA-119 similar to other file names, but do not force a dot or add a version number. This violates ECMA-119 by allowing one "." and especially ISO level 1 by allowing DOS style 8.3 names rather than only 8 characters. (mkisofs and its clones obviously do this violation.)

1.0.0 bit15= joliet_long_names Allow for Joliet leaf names up to 103 characters rather than up to 64.

#define isoburn_igopt_rockridge   1
 

Which extensions to support.

Since:
0.1.0
Parameters:
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 GNU/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
Since:
0.4.2 Produce and write MD5 checksum tags of superblock, directory tree, and the whole session stream. bit7= file_md5

0.4.2 Produce and write MD5 checksums for each single IsoFile. bit8= file_stability (only together with file_md5)

0.4.2 Compute MD5 of each file before copying it into the image and compare this with the MD5 of the actual copying. If they do not match then issue MISHAP event. See also libisofs.h iso_write_opts_set_record_md5() bit9= no_emul_toc

0.5.8 On overwriteable media or random access files do not write the first session to LBA 32 and do not copy the first 64kB of the first session to LBA 0, but rather write the first session to LBA 0 directly. bit10= will_cancel

0.6.6 Announce to libisofs that only the image size is desired and that the write thread will be cancelled by isoburn_cancel_prepared_write() before actual image writing occurs. Without this, cancellation can cause a MISHAP event. bit11= old_empty

1.0.2 Let symbolic links and device files point to block 0, and let empty data files point to the address of the Volume Descriptor Set Terminator. This was done by libisofs in the past. By default there is now a single dedicated block of zero bytes after the end of the directory trees, of which the address is used for all files without own content.

Which existing ISO 9660 extensions in the image to read or not to read.

Whether to read the content of an existing image at all. The bits can be combined by | resp. inquired by &.

Since:
0.1.0
Parameters:
ext Bitfield: bit0= norock Do not read Rock Ridge extensions bit1= nojoliet Do not read Joliet extensions bit2= noiso1999 Do not read ISO 9660:1999 enhanced tree bit3= preferjoliet When both Joliet and RR extensions are present, the RR tree is used. If you prefer using Joliet, set this to 1. bit4= pretend_blank Always create empty image.Ignore any image on input drive. bit5= noaaip
Since:
0.3.4 Do not load AAIP information from image. This information eventually contains ACL or XFS-style Extended Attributes. bit6= noacl

0.3.4 Do not obtain ACL from external filesystem objects (e.g. local filesystem files). bit7= noea

0.3.4 Do not obtain XFS-style Extended Attributes from external filesystem objects (e.g. local filesystem files). bit8= noino

0.4.0 Do not load eventual inode numbers from RRIP entry PX, but generate a new unique inode number for each imported IsoNode object. PX inode numbers allow to mark families of hardlinks by giving all family members the same inode number. libisofs keeps the PX inode numbers unaltered when IsoNode objects get written into an ISO image. bit9= nomd5

0.4.2 Do not load the eventual MD5 checksum array. Do not check eventual session_md5 tags. bit10= nomd5tag

1.0.4 Do not check eventual session_md5 tags although bit9 is not set.

Function Documentation

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.

Since:
0.1.0
Parameters:
d The output drive to which the session was written
Returns:
1 success , <=0 failure

int isoburn_attach_image struct burn_drive *  d,
IsoImage *  image
 

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 the medium. 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.

Since:
0.1.0
Parameters:
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.
Returns:
<=0 error , 1 = success

int isoburn_cancel_prepared_write struct burn_drive *  input_drive,
struct burn_drive *  output_drive,
int  flag
 

Revoke isoburn_prepare_*() instead of running isoburn_disc_write().

libisofs reserves resources and maybe already starts generating the image stream when one of above three calls is performed. It is mandatory to either run isoburn_disc_write() or to revoke the preparations by the call described here. If this call returns 0 or 1 then the write thread of libisofs has ended.

Since:
0.1.0
Parameters:
input_drive The drive resp. in_drive which was used with the preparation call.
output_drive The out_drive used with isoburn_prepare_new_image(), NULL if none.
flag Bitfield, submit 0 for now. bit0= -reserved for internal use-
Returns:
<0 error, 0= no pending preparations detectable, 1 = canceled

off_t isoburn_disc_available_space struct burn_drive *  d,
struct burn_write_opts *  o
 

Return the best possible estimation of the currently available capacity of the medium.

This might depend on particular write option settings and on drive state. An eventual start address for emulated multi-session will be subtracted from the capacity estimation given by burn_disc_available_space(). Negative results get defaulted to 0. Wrapper for: burn_disc_available_space()

Since:
0.1.0
Parameters:
d The drive to query.
o If not NULL: write parameters to be set on drive before query
Returns:
number of most probably available free bytes

int isoburn_disc_erasable struct burn_drive *  d  ) 
 

Tells whether the medium can be treated by isoburn_disc_erase().

Wrapper for: burn_disc_erasable()

Since:
0.1.0
Parameters:
d The drive to inquire.
Returns:
0=not erasable , else erasable

void isoburn_disc_erase struct burn_drive *  drive,
int  fast
 

Mark the medium as blank.

With multi-session media this will call burn_disc_erase(). With random access media, an eventual ISO-9660 filesystem will get invalidated by altering its start blocks on the medium. In case of success, the medium is in status BURN_DISC_BLANK afterwards. Wrapper for: burn_disc_erase()

Since:
0.1.0
Parameters:
drive The drive with the medium to erase.
fast 1=fast erase, 0=thorough erase With DVD-RW, fast erase yields media incapable of multi-session.

int isoburn_disc_get_msc1 struct burn_drive *  d,
int *  start_lba
 

Obtain the start block number of the most recent session on the medium.

In case of random access media this will normally be 0. Successfull return is not a guarantee that there is a ISO-9660 image at all. The call will fail, nevertheless,if isoburn_disc_get_status() returns not BURN_DISC_APPENDABLE or BURN_DISC_FULL. Note: The result of this call may be fabricated by a previous call of isoburn_set_msc1() which can override the rule to load the most recent session. Wrapper for: burn_disc_get_msc1()

Since:
0.1.0
Parameters:
d The drive to inquire
start_lba Contains on success the start address in 2048 byte blocks
Returns:
<=0 error , 1 = success

enum burn_disc_status isoburn_disc_get_status struct burn_drive *  drive  ) 
 

Inquire the medium status.

Expect the whole spectrum of libburn BURN_DISC_* with multi-session media. Emulated states with random access media are BURN_DISC_BLANK and BURN_DISC_APPENDABLE. Wrapper for: burn_disc_get_status()

Since:
0.1.0
Parameters:
drive The drive to inquire.
Returns:
The status of the drive, or what kind of disc is in it. Note: BURN_DISC_UNGRABBED indicates wrong API usage

int isoburn_disc_track_lba_nwa struct burn_drive *  d,
struct burn_write_opts *  o,
int  trackno,
int *  lba,
int *  nwa
 

Use this with trackno==0 to obtain the predicted start block number of the new session.

The interesting number is returned in parameter nwa. Wrapper for: burn_disc_track_lba_nwa()

Since:
0.1.0
Parameters:
d The drive to inquire
o If not NULL: write parameters to be set on drive before query
trackno Submit 0.
lba return value: start lba
nwa return value: Next Writeable Address
Returns:
1=nwa is valid , 0=nwa is not valid , -1=error

void isoburn_disc_write struct burn_write_opts *  o,
struct burn_disc *  disc
 

Start writing of the new session.

This call is asynchrounous. I.e. it returns quite soon and the progress has to be watched by a loop with call burn_drive_get_status() until BURN_DRIVE_IDLE is returned. Wrapper for: burn_disc_write()

Since:
0.1.0
Parameters:
o Options which control the burn process. See burnwrite_opts_*() in libburn.h.
disc Disc object created either by isoburn_prepare_disc() or by isoburn_prepare_new_image().

int isoburn_drive_aquire struct burn_drive_info *  drive_infos[],
char *  adr,
int  flag
 

Aquire a target drive by its filesystem path resp.

libburn persistent address. This is a modern successor of isoburn_drive_scan_and_grab(). Wrapper for: burn_drive_scan_and_grab()

Since:
0.1.2
Parameters:
drive_infos On success returns a one element array with the drive (cdrom/burner). Thus use with driveno 0 only. On failure the array has no valid elements at all. The returned array should be freed via burn_drive_info_free() when the drive is no longer needed. But before this is done one has to call isoburn_drive_release(drive_infos[0].drive).
adr The persistent address of the desired drive.
flag bit0= attempt to load the disc tray. Else: failure if not loaded. bit1= regard overwriteable media as blank bit2= if the drive is a regular disk file: truncate it to the write start address when writing begins bit3= if the drive reports a read-only profile try to read table of content by scanning for ISO image headers. (depending on media type and drive this might help or it might make the resulting toc even worse) bit4= do not emulate table of content on overwriteable media bit5= ignore ACL from external filesystems bit6= ignore POSIX Extended Attributes from external filesystems bit7= pretend read-only profile and scan for table of content bit8= re-assess already aquired (*drive_infos)[0] rather than aquiring adr
Since:
1.1.8
Returns:
1 = success , 0 = drive not found , <0 = other error

int isoburn_drive_grab struct burn_drive *  drive,
int  load
 

Aquire a drive from the burn_drive_info[] array which was obtained by a previous call of burn_drive_scan().

Wrapper for: burn_drive_grab()

Since:
0.1.0
Parameters:
drive The drive to grab. E.g. drive_infos[1].drive . Call isoburn_drive_release(drive) when it it no longer needed.
load 1 attempt to load the disc tray. 0 no attempt, rather failure.
Returns:
1 success, <=0 failure

void isoburn_drive_release struct burn_drive *  drive,
int  eject
 

Release an aquired drive.

Wrapper for: burn_drive_release()

Since:
0.1.0
Parameters:
drive The drive to be released
eject 1= eject medium from drive , 0= do not eject

int isoburn_drive_scan_and_grab struct burn_drive_info *  drive_infos[],
char *  adr,
int  load
 

Aquire a target drive by its filesystem path resp.

libburn persistent address. Wrapper for: burn_drive_scan_and_grab()

Since:
0.1.0
Parameters:
drive_infos On success returns a one element array with the drive (cdrom/burner). Thus use with driveno 0 only. On failure the array has no valid elements at all. The returned array should be freed via burn_drive_info_free() when the drive is no longer needed. But before this is done one has to call isoburn_drive_release(drive_infos[0].drive).
adr The persistent address of the desired drive.
load 1 attempt to load the disc tray. 0 no attempt,rather failure.
Returns:
1 = success , 0 = drive not found , <0 = other error

int isoburn_drive_set_msgs_submit struct burn_drive *  d,
int(*)(void *handle, int error_code, char msg_text[], int os_errno, char severity[], int flag)  msgs_submit,
void *  submit_handle,
int  submit_flag,
int  flag
 

Attach to a drive an application provided method for immediate delivery of messages.

If no method is set or if the method is set to NULL then libisoburn delivers messages of the drive through the global msgs_submit() method set by isoburn_set_msgs_submiti() or by the message queue of libburn.

Since:
0.2.0
Parameters:
d The drive to which this function, handle and flag shall apply
msgs_submit The function call which implements the method
submit_handle Handle to be used as first argument of msgs_submit
submit_flag Flag to be used as last argument of msgs_submit
flag Unused yet, submit 0

int isoburn_drive_wrote_well struct burn_drive *  d  ) 
 

Inquire whether the most recent write run was successful.

Wrapper for: burn_drive_wrote_well()

Since:
0.1.0
Parameters:
d The drive to inquire
Returns:
1=burn seems to have went well, 0=burn failed

void isoburn_finish void   ) 
 

Shutdown all three libraries.

Wrapper for : iso_finish() and burn_finish().

Since:
0.1.0

IsoImage* isoburn_get_attached_image struct burn_drive *  d  ) 
 

Get the image attached to a drive, if any.

Since:
0.1.0
Parameters:
d The drive to inquire
Returns:
A reference to attached image, or NULL if the drive has no image attached. This reference needs to be released via iso_image_unref() when it is not longer needed.

int isoburn_get_fifo_status struct burn_drive *  d,
int *  size,
int *  free_bytes,
char **  status_text
 

Inquire state and fill parameters of the fifo which is attached to the emerging track.

This should be done in the pacifier loop while isoburn_disc_write() or burn_disc_write() are active. This works only with drives obtained by isoburn_drive_scan_and_grab() or isoburn_drive_grab(). If isoburn_prepare_new_image() was used, then parameter out_drive must have announced the track output drive. Hint: If only burn_write_opts and not burn_drive is known, then the drive can be obtained by burn_write_opts_get_drive().

Since:
0.1.0
Parameters:
d The drive to which the track with the fifo gets burned.
size The total size of the fifo
free_bytes The current free capacity of the fifo
status_text Returns a pointer to a constant text, see below
Returns:
<0 reply invalid, >=0 fifo status code: bit0+1=input status, bit2=consumption status, i.e: 0="standby" : data processing not started yet 1="active" : input and consumption are active 2="ending" : input has ended without error 3="failing" : input had error and ended, 4="unused" : ( consumption has ended before processing start ) 5="abandoned" : consumption has ended prematurely 6="ended" : consumption has ended without input error 7="aborted" : consumption has ended after input error

int isoburn_get_img_partition_offset struct burn_drive *  drive,
uint32_t *  block_offset_2k
 

Inquire the partition offset of the loaded image.

The first 512 bytes of the image get examined whether they bear an MBR signature and a first partition table entry which matches the size of the image. In this case the start address is recorded as partition offset and internal buffers get adjusted. See also isoburn_igopt_set_part_offset().

Since:
0.6.2
Parameters:
drive The drive with the loaded image
block_offset_2k returns the recognized partition offset
Returns:
<0 = error 0 = no partition offset recognized 1 = acceptable non-zero offset, buffers are adjusted 2 = offset is credible but not acceptable for buffer size

int isoburn_get_min_start_byte struct burn_drive *  d,
off_t *  start_byte,
int  flag
 

Obtain the size which was attributed to an emulated appendable on actually overwriteable media.

This value is supposed to be <= 2048 * nwa as of isoburn_disc_track_lba_nwa().

Since:
0.1.0
Parameters:
d The drive holding the medium.
start_byte The reply value counted in bytes, not in sectors.
flag Unused yet. Submit 0.
Returns:

Since:
0.3.2
Parameters:
d The drive where msc1 is to be set
adr_mode Determines how to interpret the input adr_value. If adr_value shall represent a number then decimal ASCII digits are expected. 0= start lba of last session in TOC, ignore adr_value 1= start lba of session number given by adr_value 2= start lba of track given number by adr_value 3= adr_value itself is the lba to be used 4= start lba of last session with volume id given by adr_value
adr_value A string describing the value to be eventually used.
lba returns the block address of the entity, -1 means invalid
track returns the track number of the entity, -1 means invalid
session returns the session number of the entity, -1 means invalid
volid returns the volume id of the entity if it is a ISO session
flag Bitfield for control purposes. bit2= with adr_mode 4: use adr_value as regular expression
Returns:
<=0 error , 1 ok, ISO session, 2 ok, not an ISO session

int isoburn_igopt_attach_jte struct isoburn_imgen_opts *  opts,
void *  libjte_handle
 

Associate a libjte environment object to the upcomming write run.

libjte implements Jigdo Template Extraction as of Steve McIntyre and Richard Atterer. A non-NULL libjte_handle will cause failure to write if libjte was not enabled in libisofs at compile time.

Since:
0.6.4
Parameters:
opts The option set to work on
libjte_handle Pointer to a struct libjte_env e.g. created by libjte_new(). It must stay existent from the start of image writing by isoburn_prepare_*() until the write thread has ended. E.g. until libburn indicates the end of its write run.
Returns:
1 success, <=0 failure

int  replace_dir_mode,
int  replace_file_mode,
mode_t  dir_mode,
mode_t  file_mode
 

Set the override values for files and directory permissions.

The parameters replace_* these take one of three values: 0, 1 or 2. If 0, the corresponding attribute will be kept as set in the IsoNode at the time of image generation. If set to 1, the corresponding attrib. will be changed by a default suitable value. With value 2, the attrib. will be changed with the value specified in the corresponding *_mode options. Note that only the permissions are set, the file type remains unchanged.

Since:
0.1.0
Parameters:
o The option set to work on
replace_dir_mode whether and how to override directories
replace_file_mode whether and how to override files of other type
dir_mode Mode to use on dirs with replace_dir_mode == 2.
file_mode; Mode to use on files with replace_file_mode == 2.

int isoburn_igopt_set_part_offset struct isoburn_imgen_opts *  opts,
uint32_t  block_offset_2k,
int  secs_512_per_head,
int  heads_per_cyl
 

Control production of a second set of volume descriptors (superblock) and directory trees, together with a partition table in the MBR where the first partition has non-zero start address and the others are zeroed.

The first partition stretches to the end of the whole ISO image. The additional volume descriptor set and trees will allow to mount the ISO image at the start of the first partition, while it is still possible to mount it via the normal first volume descriptor set and tree at the start of the image resp. storage device. This makes few sense on optical media. But on USB sticks it creates a conventional partition table which makes it mountable on e.g. Linux via /dev/sdb and /dev/sdb1 alike.

Since:
0.6.2
Parameters:
opts The option set to be manipulated.
block_offset_2k The offset of the partition start relative to device start. This is counted in 2 kB blocks. The partition table will show the according number of 512 byte sectors. Default is 0 which causes no second set and trees. If it is not 0 then it must not be smaller than 16.
secs_512_per_head Number of 512 byte sectors per head. 1 to 63. 0=automatic.
heads_per_cyl Number of heads per cylinder. 1 to 255. 0=automatic.
Returns:
1 success, <=0 failure

int isoburn_igopt_set_partition_img struct isoburn_imgen_opts *  opts,
int  partition_number,
uint8_t  partition_type,
char *  image_path
 

Cause an arbitrary data file to be appended to the ISO image and to be described by a partition table entry in an MBR or SUN Disk Label at the start of the ISO image.

The partition entry will bear the size of the image file rounded up to the next multiple of 2048 bytes. MBR or SUN Disk Label are selected by isoburn_igopt_set_system_area() system area type: 0 selects MBR partition table. 3 selects a SUN partition table with 320 kB start alignment.

Since:
0.6.4
Parameters:
opts The option set to be manipulated.
partition_number Depicts the partition table entry which shall describe the appended image. Range with MBR: 1 to 4. 1 will cause the whole ISO image to be unclaimable space before partition 1.
Since:
0.6.6 Range with SUN Disk Label: 2 to 8.
Parameters:
image_path File address in the local file system. With SUN Disk Label: an empty name causes the partition to become a copy of the next lower partition.
image_type The MBR partition type. E.g. FAT12 = 0x01 , FAT16 = 0x06, Linux Native Partition = 0x83. See fdisk command L. This parameter is ignored with SUN Disk Label.
Returns:
<=0 = error, 1 = success

int isoburn_igopt_set_pvd_times struct isoburn_imgen_opts *  opts,
time_t  creation_time,
time_t  modification_time,
time_t  expiration_time,
time_t  effective_time,
char *  uuid
 

Explicitely set the four timestamps of the emerging ISO image.

Default with all parameters is 0.

Since:
0.5.4
Parameters:
opts The option set to work on
creation_time ECMA-119 Volume Creation Date and Time When "the information in the volume was created." A value of 0 means that the timepoint of write start is to be used.
modification_time ECMA-119 Volume Modification Date and Time When "the informationin the volume was last modified." A value of 0 means that the timepoint of write start is to be used.
expiration_time ECMA-119 Volume Expiration Date and Time When "the information in the volume may be regarded as obsolete." A value of 0 means that the information never shall expire.
effective_time ECMA-119 Volume Effective Date and Time When "the information in the volume may be used." A value of 0 means that not such retention is intended.
uuid If this text is not empty, then it overrides vol_modification_time by copying the first 16 decimal digits from uuid, eventually padding up with decimal '1', and writing a NUL-byte as timezone GMT. It should express a reasonable time in form YYYYMMDDhhmmsscc E.g.: 2010040711405800 = 7 Apr 2010 11:40:58 (+0 centiseconds)
Returns:
1 success, <=0 failure

int isoburn_igopt_set_relaxed struct isoburn_imgen_opts *  o,
int  relax
 

int isoburn_igopt_set_scdbackup_tag struct isoburn_imgen_opts *  o,
char *  name,
char *  timestamp,
char *  tag_written
 

Set resp.

get parameters "name" and "timestamp" for a scdbackup checksum tag. It will be appended to the libisofs session tag if the image starts at LBA 0. See isoburn_disc_track_lba_nwa. The scdbackup tag can be used to verify the image by command scdbackup_verify $device -auto_end. See scdbackup/README appendix VERIFY for its inner details.

Since:
0.4.4
Parameters:
o The option set to work on
name The tag name. 80 characters max.
timestamp A string of up to 13 characters YYMMDD.hhmmss A9 = 2009, B0 = 2010, B1 = 2011, ... C0 = 2020, ...
tag_written Either NULL or the address of an array with at least 512 characters. In the latter case the eventually produced scdbackup tag will be copied to this array when the image gets written. This call sets scdbackup_tag_written[0] = 0 to mark its preliminary invalidity.
Returns:
1 success, <=0 failure

int isoburn_igopt_set_sort_files struct isoburn_imgen_opts *  o,
int  value
 

int isoburn_igopt_set_system_area struct isoburn_imgen_opts *  o,
char  data[32768],
int  options
 

Attach 32 kB of binary data which shall get written to the first 32 kB of the ISO image, the System Area.

options can cause manipulations of these data before writing happens. If system area data are giveni or options bit0 is set, then bit1 of el_torito_set_isolinux_options() is automatically disabled.

Since:
0.5.4
Parameters:
o The option set to work on
data Either NULL or 32 kB of data. Do not submit less bytes !
options Can cause manipulations of submitted data before they get written: bit0= apply a --protective-msdos-label as of grub-mkisofs. This means to patch bytes 446 to 512 of the system area so that one partition is defined which begins at the second 512-byte block of the image and ends where the image ends. This works with and without system_area_data. bit1= apply isohybrid MBR patching to the system area. This works only with system area data from SYSLINUX plus an ISOLINUX boot image (see iso_image_set_boot_image()) and only if not bit0 is set. bit2-7= System area type 0= with bit0 or bit1: MBR else: unspecified type
Since:
0.6.4 1= MIPS Big Endian Volume Header Submit up to 15 MIPS Big Endian boot files by iso_image_add_mips_boot_file() of libisofs. This will overwrite the first 512 bytes of the submitted data. 2= DEC Boot Block for MIPS Little Endian The first boot file submitted by iso_image_add_mips_boot_file() will be activated. This will overwrite the first 512 bytes of the submitted data.

0.6.6 3= SUN Disk Label for SUN SPARC Submit up to 7 SPARC boot images by isoburn_igopt_set_partition_img() for partition numbers 2 to 8. This will overwrite the first 512 bytes of the submitted data. bit8-9= Only with System area type 0 = MBR

1.0.4 Cylinder alignment mode eventually pads the image to make it end at a cylinder boundary. 0 = auto (align if bit1) 1 = always align to cylinder boundary 2 = never align to cylinder boundary

Returns:
1 success, 0 no data to get, <0 failure

int isoburn_igopt_set_tail_blocks struct isoburn_imgen_opts *  opts,
uint32_t  num_blocks
 

Set resp.

get the number of trailing zero byte blocks to be written by libisofs. The image size counter of the emerging ISO image will include them. Eventual checksums will take them into respect. They will be written immediately before the eventual image checksum area which is at the very end of the image. For a motivation see iso_write_opts_set_tail_blocks() in libisofs.h .

Since:
0.6.4
Parameters:
opts The option set to work on num_blocks Number of extra 2 kB blocks to be written by libisofs.
Returns:
1 success, <=0 failure

int isoburn_igopt_set_untranslated_name_len struct isoburn_imgen_opts *  o,
int  len
 

Caution: This option breaks any assumptions about names that are supported by ECMA-119 specifications.

Try to omit any translation which would make a file name compliant to the ECMA-119 rules. This includes and exceeds omit_version_numbers, max_37_char_filenames, no_force_dots bit0, allow_full_ascii. Further it prevents the conversion from local character set to ASCII. The maximum name length is given by this call. If a filename exceeds this length or cannot be recorded untranslated for other reasons, then image production gets aborted. Currently the length limit is 96 characters, because an ECMA-119 directory record may at most have 254 bytes and up to 158 other bytes must fit into the record. Probably 96 more bytes can be made free for the name in future.

Since:
1.0.0
Parameters:
o The option set to work on
len 0 = disable this feature and perform name translation according to other settings. >0 = Omit any translation. Eventually abort image production if a name is longer than the given value. -1 = Like >0. Allow maximum possible length. isoburn_igopt_get_untranslated_name_len() will tell the effectively resulting value.
Returns:
>0 success, <=0 failure

int isoburn_initialize char  msg[1024],
int  flag
 

Initialize libisoburn, libisofs and libburn.

Wrapper for : iso_init() and burn_initialize()

Since:

Parameters:
msg A character array for eventual messages (e.g. with errors)
flag Bitfield for control purposes (unused yet, submit 0)
Returns:
1 indicates success, 0 is failure

int isoburn_is_compatible int  major,
int  minor,
int  micro,
int  flag
 

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 libisoburn.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...

Since:
0.1.0
Parameters:
major obtained at build time
minor obtained at build time
micro obtained at build time
flag Bitfield for control purposes. Unused yet. Submit 0.
Returns:
1= library can work for caller 0= library is not usable in some aspects. Caller must restrict itself to an earlier API version or must not use this libray at all.

int isoburn_libburn_req int *  major,
int *  minor,
int *  micro
 

The minimum version of libburn to be used with this version of libisoburn at runtime.

This is checked already in isoburn_initialize() which will refuse on outdated version. So this call is for information purposes after successful startup only.

Since:
0.1.0
Parameters:
major isoburn_libburn_req_major as seen at build time
minor as seen at build time
micro as seen at build time
Returns:
1 success, <=0 might in future become an error indication

int isoburn_libisofs_req int *  major,
int *  minor,
int *  micro
 

The minimum version of libisofs to be used with this version of libisoburn at runtime.

This is checked already in isoburn_initialize() which will refuse on outdated version. So this call is for information purposes after successful startup only.

Since:
0.1.0
Parameters:
major isoburn_libisofs_req_major as seen at build time
minor as seen at build time
micro as seen at build time
Returns:
1 success, <=0 might in future become an error indication

int isoburn_libjte_req int *  major,
int *  minor,
int *  micro
 

The minimum version of libjte to be used with this version of libisoburn at runtime.

The use of libjte is optional and depends on configure tests. It can be prevented by ./configure option --disable-libjte . This is checked already in isoburn_initialize() which will refuse on outdated version. So this call is for information purposes after successful startup only.

Since:
0.6.4

int isoburn_needs_emulation struct burn_drive *  d  ) 
 

Inquire wether the medium needs emulation or would be suitable for generic multi-session via libburn.

Since:
0.1.0
Parameters:
d The drive to inquire
Returns:
0 is generic multi-session 1 is emulated multi-session -1 is not suitable for isoburn

int isoburn_prepare_blind_grow struct burn_drive *  in_drive,
struct burn_disc **  disc,
struct isoburn_imgen_opts *  opts,
struct burn_drive *  out_drive,
int  nwa
 

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 medium $nwa is a parameter of this call or can be used as detected from the in_drive medium

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().

Since:
0.2.2
Parameters:
in_drive The input drive,grabbed with isoburn_drive_scan_and_grab().
disc Returns the newly created burn_disc object.
opts Options for image generation and data transport to media.
out_drive The output drive, from isoburn_drive_aquire() et.al.. typically stdio:/dev/fd/1 .
nwa The address (2048 byte block count) where the add-on session will be finally stored on a mountable medium or in a mountable file. If nwa is -1 then the address is used as determined from the in_drive medium.
Returns:
<=0 error , 1 = success

int isoburn_prepare_disc struct burn_drive *  drive,
struct burn_disc **  disc,
struct isoburn_imgen_opts *  opts
 

To choose the expansion method of Growing: Create a disc object for writing the new session from the created or loaded iso_volset which has been manipulated via libisofs, to the same medium from where the image was eventually loaded.

This struct burn_disc is ready for use by a subsequent call to isoburn_disc_write(). After this asynchronous writing has ended and the drive is BURN_DRIVE_IDLE again, the burn_disc object has to be disposed by burn_disc_free().

Since:
0.1.0
Parameters:
drive The combined source and target drive, grabbed with isoburn_drive_scan_and_grab(). .
disc Returns the newly created burn_disc object.
opts Image generation options, see isoburn_igopt_*()
Returns:
<=0 error , 1 = success

int isoburn_prepare_new_image struct burn_drive *  in_drive,
struct burn_disc **  disc,
struct isoburn_imgen_opts *  opts,
struct burn_drive *  out_drive
 

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 medium. 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().

Since:
0.1.0
Parameters:
in_drive The input drive, grabbed with isoburn_drive_aquire() or one of its alternatives.
disc Returns the newly created burn_disc object.
opts Options for image generation and data transport to the medium.
out_drive The output drive, from isoburn_drive_aquire() et.al..
Returns:
<=0 error , 1 = success

int isoburn_read_image struct burn_drive *  d,
struct isoburn_read_opts *  read_opts,
IsoImage **  image
 

Load the ISO filesystem directory tree from the medium 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.

Since:
0.1.0
Parameters:
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.
Returns:
<=0 error , 1 = success

Parameters:
d The drive with the medium to inspect
lba The block number from where to read
image_blocks Returns the number of 2048 bytes blocks in the session
info Caller provided memory, enough to take eventual info reply
flag bit0-7: info return mode 0= do not return anything in info (do not even touch it) 1= copy volume id to info (info needs 33 bytes) 2=
Since:
0.2.2 : copy 64 kB header to info (needs 65536 bytes) bit13=

0.2.2: do not read head from medium but use first 64 kB from info bit14= check both half buffers (not only second) return 2 if found in first block bit15= return -1 on read error

Returns:

int isoburn_ropt_set_default_dirperms struct isoburn_read_opts *  o,
mode_t  mode
 

Default attributes to use on directories if no RockRidge extension gets loaded.

Above call isoburn_ropt_set_default_perms() automatically adds x-permissions to r-permissions for directories. This call here may be done afterwards to set independend permissions for directories, especially to override the automatically added x-permissions.

Since:
0.1.0
Parameters:
o The option set to work on
mode permissions (not file type) as of man 2 stat.
Returns:
1 success, <=0 failure

int isoburn_ropt_set_default_perms struct isoburn_read_opts *  o,
uid_t  uid,
gid_t  gid,
mode_t  mode
 

Default attributes to use if no RockRidge extension gets loaded.

Since:
0.1.0
Parameters:
o The option set to work on
uid user id number (see /etc/passwd)
gid group id number (see /etc/group)
mode permissions (not file type) as of man 2 stat. With directories, r-permissions will automatically imply x-permissions. See isoburn_ropt_set_default_dirperms() below.
Returns:
1 success, <=0 failure

int isoburn_ropt_set_displacement struct isoburn_read_opts *  o,
uint32_t  displacement,
int  displacement_sign
 

Control an offset to be applied to all block address pointers in the ISO image in order to compensate for an eventual displacement of the image relative to the start block address for which it was produced.

E.g. if track number 2 from CD gets copied into a disk file and shall then be loaded as ISO filesystem, then the directory tree and all data file content of the track copy will become readable by setting the track start address as displacement and -1 as displacement_sign. Data file content outside the track will of course not be accessible and eventually produce read errors.

Since:
0.6.6
Parameters:
o The option set to work on
displacement 0 or a positive number
displacement_sign Determines wether to add or subtract displacement to block addresses before applying them to the storage object for reading: +1 = add , -1= subtract , else keep unaltered

int isoburn_ropt_set_extensions struct isoburn_read_opts *  o,
int  ext
 

int isoburn_ropt_set_input_charset struct isoburn_read_opts *  o,
char *  input_charset
 

Set the character set for reading RR file names from ISO images.

Since:
0.1.0
Parameters:
o The option set to work on
input_charset Set this to NULL to use the default locale charset For selecting a particular character set, submit its name, e.g. as listed by program iconv -l. Example: "UTF-8".
Returns:
1 success, <=0 failure

int isoburn_set_msc1 struct burn_drive *  d,
int  adr_mode,
char *  adr_value,
int  flag
 

Set up isoburn_disc_get_msc1() to return a fabricated value.

This makes only sense between aquiring the drive and reading the image. After isoburn_read_image() it will confuse the coordination of libisoburn and libisofs. Note: Sessions and tracks are counted beginning with 1, not with 0.

Since:
0.1.6
Parameters:
d The drive where msc1 is to be set
adr_mode Determines how to interpret adr_value and to set msc1. If adr_value shall represent a number then decimal ASCII digits are expected. 0= start lba of last session in TOC, ignore adr_value 1= start lba of session number given by adr_value 2= start lba of track given number by adr_value 3= adr_value itself is the lba to be used 4= start lba of last session with volume id given by adr_value
adr_value A string describing the value to be eventually used.
flag Bitfield for control purposes. bit0=
Since:
0.2.2 with adr_mode 3: adr_value might be 16 blocks too high (e.g. -C stemming from growisofs). Probe for ISO head at adr_value-16 and eventually adjust setting. bit1= insist in seeing a disc object with at least one session bit2= with adr_mode 4: use adr_value as regular expression

int isoburn_set_msgs_submit int(*)(void *handle, int error_code, char msg_text[], int os_errno, char severity[], int flag)  msgs_submit,
void *  submit_handle,
int  submit_flag,
int  flag
 

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.

Parameters:
msgs_submit The function call which implements the method
submit_handle Handle to be used as first argument of msgs_submit
submit_flag Flag to be used as last argument of msgs_submit
flag Unused yet, submit 0
Since:
0.2.0

int isoburn_set_read_pacifier struct burn_drive *  drive,
int(*)(IsoImage *, IsoFileSource *)  read_pacifier,
void *  app_handle
 

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.

Since:
0.1.0
Parameters:
drive The drive which will be used with isoburn_read_image() It has to be aquired by an isoburn_* wrapper call.
read_pacifier The callback function
app_handle The app handle which the callback function can obtain via iso_image_get_attached_data() from its IsoImage*
Returns:
1 success, <=0 failure

int isoburn_set_truncate struct burn_drive *  drive,
int  flag
 

Override the truncation setting that was made with flag bit2 during the call of isoburn_drive_aquire.

This applies only to stdio pseudo drives.

Since:
0.1.6
Parameters:
drive The drive which was aquired and shall be used for writing.
flag Bitfield controlling the setting: bit0= truncate (else do not truncate) bit1= do not warn if call is inappropriate to drive bit2= only set if truncation is currently enabled do not warn if call is inappropriate to drive
Returns:
1 success, 0 inappropriate drive, <0 severe error

int isoburn_sync_after_write struct burn_drive *  input_drive,
struct burn_drive *  output_drive,
int  flag
 

Wait after normal end of operations until libisofs ended all write threads and freed resource reservations.

This call is not mandatory. But without it, messages from the ending threads might appear after the application ended its write procedure.

Since:
0.1.0
Parameters:
input_drive The drive resp. in_drive which was used with the preparation call.
output_drive The out_drive used with isoburn_prepare_new_image(), NULL if none.
flag Bitfield, submit 0 for now.
Returns:
<=0 error , 1 = success

void isoburn_toc_disc_free struct isoburn_toc_disc *  disc  ) 
 

Release the memory associated with a master handle of a medium.

The handle is invalid afterwards and may not be used any more. Wrapper for: burn_disc_free()

Since:
0.1.6
Parameters:
disc The master handle of the medium

int isoburn_toc_disc_get_sectors struct isoburn_toc_disc *  disc  ) 
 

Tell the number of 2048 byte blocks covered by the table of content.

This number includes the eventual gaps between sessions and tracks. So this call is not really a wrapper for burn_disc_get_sectors().

Since:
0.1.6
Parameters:
disc The master handle of the medium
Returns:
Number of blocks, <=0 indicates unknown or unreadable state

struct isoburn_toc_session** isoburn_toc_disc_get_sessions struct isoburn_toc_disc *  disc,
int *  num
 

Get the array of session handles from the table of content.

Wrapper for: burn_disc_get_sessions()

Since:
0.1.6
Parameters:
disc The master handle of the medium
num returns the number of sessions in the array
Returns:
the address of the array of session handles

struct isoburn_toc_disc* isoburn_toc_drive_get_disc struct burn_drive *  d  ) 
 

Obtain a master handle for the table of content.

This handle governs allocated resources which have to be released by isoburn_toc_disc_free() when no longer needed. Wrapper for: burn_drive_get_disc()

Since:
0.1.6
Parameters:
d The drive with the medium to inspect
Returns:
NULL in case there is no content info, else it is a valid handle

void isoburn_toc_session_get_leadout_entry struct isoburn_toc_session *  s,
struct burn_toc_entry *  entry
 

Obtain a copy of the entry which describes the end of a particular session.

Wrapper for: burn_session_get_leadout_entry()

Since:
0.1.6
Parameters:
s The session handle
entry A pointer to memory provided by the caller. It will be filled with info according to struct burn_toc_entry as defined in libburn.h

int isoburn_toc_session_get_sectors struct isoburn_toc_session *  s  ) 
 

Tell the number of 2048 byte blocks covered by a particular session.

Wrapper for: burn_session_get_sectors()

Since:
0.1.6
Parameters:
s The session handle
Returns:
number of blocks, <=0 indicates unknown or unreadable state

struct isoburn_toc_track** isoburn_toc_session_get_tracks struct isoburn_toc_session *  s,
int *  num
 

Get the array of track handles from a particular session.

Wrapper for: burn_session_get_tracks()

Since:
0.1.6
Parameters:
s The session handle
num returns the number of tracks in the array
Returns:
the address of the array of track handles, NULL if no tracks are registered with session s

int isoburn_toc_track_get_emul struct isoburn_toc_track *  t,
int *  start_lba,
int *  image_blocks,
char  volid[33],
int  flag
 

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.

Since:
0.4.0
Parameters:
t The track handle
start_lba Returns the start address of the ISO session
image_blocks Returns the number of 2048 bytes blocks
volid Caller provided memory for the volume id
flag unused yet, submit 0
Returns:
0= not an emulated ISO session , 1= reply is valid

void isoburn_toc_track_get_entry struct isoburn_toc_track *  t,
struct burn_toc_entry *  entry
 

Obtain a copy of the entry which describes a particular track.

Wrapper for: burn_track_get_entry()

Since:
0.1.6
Parameters:
t The track handle
entry A pointer to memory provided by the caller. It will be filled with info according to struct burn_toc_entry as defined in libburn.h

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().

Since:
0.1.0
Parameters:
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.

Returns:
1 success, <=0 might in future become an error indication
