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.

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

int isoburn_igopt_set_fifo_size ( struct isoburn_imgen_opts o,
int  fifo_size 
)

The number of bytes to be used for the fifo which decouples libisofs and libburn for better throughput and for reducing the risk of interrupting signals hitting the libburn thread which operates the MMC drive.

The size will be rounded up to the next full 2048. Minimum is 64kiB, maximum is 1 GiB (but that is too much anyway).

Since:
0.1.0
Parameters:
o The option set to work on
fifo_size Number of bytes to use
Returns:
1 success, <=0 failure

)

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.

Set the override values values for group id and user id.

The rules are like with above overriding of mode values. replace_* controls whether and how. The other two parameters provide values for eventual use.

Since:
0.1.0
Parameters:
o The option set to work on
replace_uid whether and how to override user ids

Explicitely set the four timestamps of the emerging ISO image.

Default with all parameters is 0.

Since:
0.5.4 ECMA-119 defines the timestamps in the Primary Volume Descriptor as:
Parameters:
creation_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 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 When "the information in the volume may be regarded as obsolete." A value of 0 means that the information never shall expire.
effective_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)

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:

int isoburn_igopt_set_system_area ( struct isoburn_imgen_opts o,
char  data[32768],

)

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

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.

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 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().

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 media or in a mountable file. If nwa is -1 then the address is used as determined from the in_drive media.
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 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().

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 media.
out_drive The output drive, from isoburn_drive_aquire() et.al..
Returns:
<=0 error , 1 = success

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
