Function Documentation

int aaip_xinfo_func ( void *  data,
int  flag 
)

Function to identify and manage AAIP strings as xinfo of IsoNode.

An AAIP string contains the Attribute List with the xattr and ACL of a node in the image tree. It is formatted according to libisofs specification AAIP-2.0 and ready to be written into the System Use Area resp. Continuation Area of a directory entry in an ISO image.

Applications are not supposed to manipulate AAIP strings directly. They should rather make use of the appropriate iso_node_get_* and iso_node_set_* calls.

AAIP represents ACLs as xattr with empty name and AAIP-specific binary content. Local filesystems may represent ACLs as xattr with names like "system.posix_acl_access". libisofs does not interpret those local xattr representations of ACL directly but rather uses the ACL interface of the local system. By default the local xattr representations of ACL will not become part of the AAIP Attribute List via iso_local_get_attrs() and not be attached to local files via iso_local_set_attrs().

Since:
0.6.2
Deprecated:
Use el_torito_set_isolinux_options() instead
int el_torito_seems_boot_info_table ( ElToritoBootImage bootimg,
int  flag 
)

Makes a guess whether the boot image was patched by a boot information table.

It is advisable to patch such boot images if their content gets copied to a new location. See el_torito_set_isolinux_options(). Note: The reply can be positive only if the boot image was imported from an existing ISO image.

Parameters:
bootimg The image to inquire
Returns:

Set the id_string of the Validation Entry resp.

Sector Header Entry which will govern the boot image Section Entry in the El Torito Catalog.

Parameters:
bootimg The image to manipulate.
id_string The first boot image puts 24 bytes of ID string into the Validation Entry, where they shall "identify the manufacturer/developer of the CD-ROM". Further boot images put 28 bytes into their Section Header. El Torito 1.0 states that "If the BIOS understands the ID string, it may choose to boot the * system using one of these entries in place of the INITIAL/DEFAULT entry." (The INITIAL/DEFAULT entry points to the first boot image.)
Returns:
1 = ok , <0 = error
Since:
0.6.32
int el_torito_set_isolinux_options ( ElToritoBootImage bootimg,
int  options,
int  flag 
)

Specifies options for ISOLINUX or GRUB boot images.

This should only be used if the type of boot image is known.

Parameters:
options bitmask style flag. The following values are defined:

bit 0 -> 1 to patch the boot info table of the boot image. 1 does the same as mkisofs option -boot-info-table. Needed for ISOLINUX or GRUB boot images with platform ID 0. The table is located at byte 8 of the boot image file. Its size is 56 bytes. The original boot image file on disk will not be modified.

One may use el_torito_seems_boot_info_table() for a qualified guess whether a boot info table is present in the boot image. If the result is 1 then it should get bit0 set if its content gets copied to a new LBA.

bit 1 -> 1 to generate a ISOLINUX isohybrid image with MBR. ----------------------------------------------------------

Deprecated:
since 31 Mar 2010: The author of syslinux, H. Peter Anvin requested that this feature shall not be used any more. He intends to cease support for the MBR template that is included in libisofs. ---------------------------------------------------------- A hybrid image is a boot image that boots from either CD/DVD media or from disk-like media, e.g. USB stick. For that you need isolinux.bin from SYSLINUX 3.72 or later. IMPORTANT: The application has to take care that the image on media gets padded up to the next full MB.
Parameters:
flag Reserved for future usage, set to 0.

int iso_dir_add_node ( IsoDir dir,
IsoNode child,
enum iso_replace_mode  replace 
)

Add a new node to a dir.

Note that this function don't add a new ref to the node, so you don't need to free it, it will be automatically freed when the dir is deleted. Of course, if you want to keep using the node after the dir life, you need to iso_node_ref() it.

Parameters:
dir the dir where to add the node
child the node to add. You must ensure that the node hasn't previously added to other dir, and that the node name is unique inside the child. Otherwise this function will return a failure, and the child won't be inserted.
replace if the dir already contains a node with the same name, whether to replace or not the old node with this.
Returns:
number of nodes in dir if succes, < 0 otherwise Possible errors: ISO_NULL_POINTER, if dir or child are NULL ISO_NODE_ALREADY_ADDED, if child is already added to other dir ISO_NODE_NAME_NOT_UNIQUE, a node with same name already exists ISO_WRONG_ARG_VALUE, if child == dir, or replace != (0,1)

Since:
0.6.4
int iso_dir_get_children ( const IsoDir dir,
IsoDirIter **  iter 
)

Get an iterator for the children of the given dir.

You can iterate over the children with iso_dir_iter_next. When finished, you should free the iterator with iso_dir_iter_free. You musn't delete a child of the same dir, using iso_node_take() or iso_node_remove(), while you're using the iterator. You can use iso_dir_iter_take() or iso_dir_iter_remove() instead.

You can use the iterator in the way like this

IsoDirIter *iter; IsoNode *node; if ( iso_dir_get_children(dir, &iter) != 1 ) { // handle error } while ( iso_dir_iter_next(iter, &node) == 1 ) { // do something with the child } iso_dir_iter_free(iter);

An iterator is intended to be used in a single iteration over the children of a dir. Thus, it should be treated as a temporary object, and free as soon as possible.

Returns:
1 success, < 0 error Possible errors: ISO_NULL_POINTER, if dir or iter are NULL ISO_OUT_OF_MEM
Since:

Parameters:
dir The dir where to look for the node.
name The name of the node
node Location for a pointer to the node, it will filled with NULL if the dir doesn't have a child with the given name. The node will be owned by the dir and shouldn't be unref(). Just call iso_node_ref() to get your own reference to the node. Note that you can pass NULL is the only thing you want to do is check if a node with such name already exists on dir.
Returns:
1 node found, 0 child has no such node, < 0 error Possible errors: ISO_NULL_POINTER, if dir or name are NULL
Since:

It can then be inquired by iso_file_get_md5() and will get written into the next session if this is enabled at write time and if the image write process does not compute an MD5 from content which it copies. So this call can be used to equip nodes from the old image with checksums or to make available checksums of newly added files before the session gets written.

Parameters:
file The file object to read data from and to which to attach the checksum. If the file is from the imported image, then its most original stream will be checksummed. Else the eventual filter streams will get into effect.
flag Bitfield for control purposes. Unused yet. Submit 0.
Returns:
1= ok, MD5 is computed and attached , <0 indicates error

0.6.22
int iso_file_remove_filter ( IsoFile file,
int  flag 
)

Delete the top filter stream from a data file.

This is the most recent one which was added by iso_file_add_*_filter(). Caution: One should not do this while the IsoStream of the file is opened. For now there is no general way to determine this state. Filter stream implementations are urged to eventually call .close() inside method .free() . This will close the input stream too.

Parameters:
file The data file node which shall get rid of one layer of content filtering.
flag Bitfield for control purposes, unused yet, submit 0.
Returns:
1 on success, 0 if no filter was present <0 on error
Since:

Parameters:
src The file source object to be inquired.
aa_string Returns a pointer to the AAIP string data. If no AAIP string is available, *aa_string becomes NULL. (See doc/susp_aaip_2_0.txt for the meaning of AAIP.) The caller is responsible for finally calling free() on non-NULL results.
flag Bitfield for control purposes bit0= Transfer ownership of AAIP string data. src will free the eventual cached data and might not be able to produce it again. bit1= No need to get ACL (but no guarantee of exclusion) bit2= No need to get xattr (but no guarantee of exclusion)

ElToritoBootImage **  boot,
IsoFile **  imgnode,
IsoBoot **  catnode 
)

Get the El-Torito boot catalog and the default boot image of an ISO image.

This can be useful, for example, to check if a volume read from a previous session or an existing image is bootable. It can also be useful to get the image and catalog tree nodes. An application would want those, for example, to prevent the user removing it.

Both nodes are owned by libisofs and should not be freed. You can get your own ref with iso_node_ref(). You can can also check if the node is already on the tree by getting its parent (note that when reading El-Torito info from a previous image, the nodes might not be on the tree even if you haven't removed them). Remember that you'll need to get a new ref (with iso_node_ref()) before inserting them again to the tree, and probably you will also need to set the name or permissions.

Parameters:
image The image from which to get the boot image.
boot If not NULL, it will be filled with a pointer to the boot image, if any. That object is owned by the IsoImage and should not be freed by the user, nor dereferenced once the last reference to the IsoImage was disposed via iso_image_unref().
imgnode When not NULL, it will be filled with the image tree node. No extra ref is added, you can use iso_node_ref() to get one if you need it.
catnode When not NULL, it will be filled with the catnode tree node. No extra ref is added, you can use iso_node_ref() to get one if you need it.

Create a new set of El-Torito bootable images by adding a boot catalog and the default boot image.

Further boot images may then be added by iso_image_add_boot_image().

Parameters:
image The image to make bootable. If it was already bootable this function returns an error and the image remains unmodified.
image_path The absolute path of a IsoFile to be used as default boot image.
type The boot media type. This can be one of 3 types:

  • Floppy emulation: Boot image file must be exactly 1200 kB, 1440 kB or 2880 kB.
  • Hard disc emulation: The image must begin with a master boot record with a single image.
  • No emulation. You should specify load segment and load size of image.
catalog_path The absolute path in the image tree where the catalog will be stored. The directory component of this path must be a directory existent on the image tree, and the filename component must be unique among all children of that directory on image. Otherwise a correspodent error code will be returned. This function will add an IsoBoot node that acts as a placeholder for the real catalog, that will be generated at image creation time.
boot Location where a pointer to the added boot image will be stored. That object is owned by the IsoImage and should not be freed by the user, nor dereferenced once the last reference to the IsoImage was disposed via iso_image_unref(). A NULL value is allowed if you don't need a reference to the boot image.

int iso_local_get_acl_text ( char *  disk_path,
char **  text,
int  flag 
)

libisofs has an internal system dependent adapter to ACL and xattr operations.

For the sake of completeness and simplicity it exposes this functionality to its applications which might want to get and set ACLs from local files. Get an ACL of the given file in the local filesystem in long text form.

Parameters:
disk_path Absolute path to the file
text Will return a pointer to the ACL text. If not NULL the text will be 0 terminated and finally has to be disposed by a call to this function with bit15 set.
flag Bitfield for control purposes bit0= get "default" ACL rather than "access" ACL bit4= set *text = NULL and return 2 if the ACL matches st_mode permissions. bit5= in case of symbolic link: inquire link target bit15= free text and return 1
Returns:
1 ok 2 ok, trivial ACL found while bit4 is set, *text is NULL 0 no ACL manipulation adapter available / ACL not supported on fs -1 failure of system ACL service (see errno) -2 attempt to inquire ACL of a symbolic link without bit4 or bit5 resp. with no suitable link target

int iso_node_add_xinfo ( IsoNode node,
iso_node_xinfo_func  proc,
void *  data 
)

Add extended information to the given node.

Extended info allows applications (and libisofs itself) to add more information to an IsoNode. You can use this facilities to associate temporary information with a given node. This information is not written into the ISO 9660 image on media and thus does not persist longer than the node memory object.

Each node keeps a list of added extended info, meaning you can add several extended info data to each node. Each extended info you add is identified by the proc parameter, a pointer to a function that knows how to manage the external info data. Thus, in order to add several types of extended info, you need to define a "proc" function for each type.

Parameters:
node The node where to add the extended info
proc A function pointer used to identify the type of the data, and that knows how to manage it
data Extended info to add.
Returns:
1 if success, 0 if the given node already has extended info of the type defined by the "proc" function, < 0 on error

int iso_node_get_acl_text ( IsoNode node,
char **  access_text,
char **  default_text,
int  flag 
)

Get the eventual ACLs which are associated with the node.

The result will be in "long" text form as of man acl resp. acl_to_text(). Call this function with flag bit15 to finally release the memory occupied by an ACL inquiry.

Parameters:
node The node that is to be inquired.
access_text Will return a pointer to the eventual "access" ACL text or NULL if it is not available and flag bit 4 is set.
default_text Will return a pointer to the eventual "default" ACL or NULL if it is not available. (GNU/Linux directories can have a "default" ACL which influences the permissions of newly created files.)
flag Bitfield for control purposes bit4= if no "access" ACL is available: return *access_text == NULL else: produce ACL from stat(2) permissions bit15= free memory and return 1 (node may be NULL)
Returns:
2 *access_text was produced from stat(2) permissions 1 *access_text was produced from ACL of node 0 if flag bit4 is set and no ACL is available < 0 on error

int iso_node_get_attrs ( IsoNode node,
size_t *  num_attrs,
char ***  names,
size_t **  value_lengths,
char ***  values,
int  flag 
)

Get the list of xattr which is associated with the node.

The resulting data may finally be disposed by a call to this function with flag bit15 set, or its components may be freed one-by-one. The following values are either NULL or malloc() memory: *names, *value_lengths, *values, (*names)[i], (*values)[i] with 0 <= i < *num_attrs. It is allowed to replace or reallocate those memory items in order to to manipulate the attribute list before submitting it to other calls.

If enabled by flag bit0, this list possibly includes the ACLs of the node. They are eventually encoded in a pair with empty name. It is not advisable to alter the value or name of that pair. One may decide to erase both ACLs by deleting this pair or to copy both ACLs by copying the content of this pair to an empty named pair of another node. For all other ACL purposes use iso_node_get_acl_text().

Parameters:
node The node that is to be inquired.
num_attrs Will return the number of name-value pairs
names Will return an array of pointers to 0-terminated names
value_lengths Will return an arry with the lenghts of values
values Will return an array of pointers to strings of 8-bit bytes
flag Bitfield for control purposes bit0= obtain eventual ACLs as attribute with empty name bit2= with bit0: do not obtain attributes other than ACLs bit15= free memory (node may be NULL)

)

Set the ACLs of the given node to the lists in parameters access_text and default_text or delete them.

The stat(2) permission bits get updated according to the new "access" ACL if neither bit1 of parameter flag is set nor parameter access_text is NULL. Note that S_IRWXG permission bits correspond to ACL mask permissions if a "mask::" entry exists in the ACL. Only if there is no "mask::" then the "group::" entry corresponds to to S_IRWXG.

Parameters:
node The node that is to be manipulated.
access_text The text to be set into effect as "access" ACL. NULL will delete an eventually existing "access" ACL of the node.
default_text The text to be set into effect as "default" ACL. NULL will delete an eventually existing "default" ACL of the node. (GNU/Linux directories can have a "default" ACL which influences the permissions of newly created files.)

)

Set the list of xattr which is associated with the node.

The data get copied so that you may dispose your input data afterwards.

If enabled by flag bit0 then the submitted list of attributes will not only overwrite xattr but also both eventual ACLs of the node. Eventual ACL in the submitted list have to reside in an attribute with empty name.

Parameters:
node The node that is to be manipulated.
num_attrs Number of attributes
names Array of pointers to 0 terminated name strings
value_lengths Array of byte lengths for each value
values Array of pointers to the value bytes
flag Bitfield for control purposes bit0= Do not maintain eventual existing ACL of the node. Set eventual new ACL from value of empty name. bit1= Do not clear the existing attribute list but merge it with the list given by this call. The given values override the values of their eventually existing names. If no xattr with a given name exists, then it will be added as new xattr. So this bit can be used to set a single xattr without inquiring any other xattr of the node. bit2= Delete the attributes with the given names bit3= Allow to affect non-user attributes. I.e. those with a non-empty name which does not begin by "user." (The empty name is always allowed and governed by bit0.) This deletes all previously existing attributes if not bit1 is set.

Set if the node will be hidden in RR/ISO tree, Joliet tree or both.

If the file is set as hidden in one tree, it wil not be included there, so it won't be visible in a OS accessing CD using that tree. For example, GNU/Linux systems access to Rock Ridge / ISO9960 tree in order to see what is recorded on CD, while MS Windows make use of the Joliet tree. If a file is hidden only in Joliet, it wil not be visible in Windows systems, while still visible in GNU/Linux.

If a file is hidden in both trees, it will not be written to image.

int iso_node_zf_by_magic ( IsoNode node,
int  flag 
)

Check for the given node or for its subtree whether the data file content effectively bears zisofs file headers and eventually mark the outcome by an xinfo data record if not already marked by a zisofs compressor filter.

This does not install any filter but only a hint for image generation that the already compressed files shall get written with zisofs ZF entries. Use this if you insert the compressed reults of program mkzftree from disk into the image.

Parameters:
node The node which shall be checked and eventually marked.
flag Bitfield for control purposes, unused yet, submit 0 bit0= prepare for a run with iso_write_opts_set_appendable(,1). Take into account that files from the imported image do not get their content filtered. bit1= permission to overwrite existing zisofs_zf_info bit2= if no zisofs header is found: create xinfo with parameters which indicate no zisofs bit3= no tree recursion if node is a directory bit4= skip files which stem from the imported image
Returns:
0= no zisofs data found 1= zf xinfo added 2= found existing zf xinfo and flag bit1 was not set 3= both encountered: 1 and 2 <0 means error

int iso_read_opts_set_new_inos ( IsoReadOpts opts,
int  new_inos 
)

Control discarding of eventual inode numbers from existing images.

Such numbers may come from RRIP 1.12 entries PX. If not discarded they get written unchanged when the file object gets written into an ISO image. If this inode number is missing with a file in the imported image, or if it has been discarded during image reading, then a unique inode number will be generated at some time before the file gets written into an ISO image. Two image nodes which have the same inode number represent two hardlinks of the same file object. So discarding the numbers splits hardlinks.

Parameters:
new_inos 1 = Discard imported inode numbers and finally hand out a unique new one to each single file before it gets written into an ISO image. 0 = Keep eventual inode numbers from PX entries. All other values are reserved.

int iso_tree_add_exclude ( IsoImage image,
const char *  path 
)

Add a excluded path.

These are paths that won't never added to image, and will be excluded even when adding recursively its parent directory.

For example, in

iso_tree_add_exclude(image, "/home/user/data/private"); iso_tree_add_dir_rec(image, root, "/home/user/data");

the directory /home/user/data/private won't be added to image.

However, if you explicity add a deeper dir, it won't be excluded. i.e., in the following example.

iso_tree_add_exclude(image, "/home/user/data"); iso_tree_add_dir_rec(image, root, "/home/user/data/private");

the directory /home/user/data/private is added. On the other, side, and foollowing the the example above,

iso_tree_add_dir_rec(image, root, "/home/user");

will exclude the directory "/home/user/data".

Absolute paths are not mandatory, you can, for example, add a relative path such as:

iso_tree_add_exclude(image, "private"); iso_tree_add_exclude(image, "user/data");

to excluve, respectively, all files or dirs named private, and also all files or dirs named data that belong to a folder named "user". Not that the above rule about deeper dirs is still valid. i.e., if you call

iso_tree_add_dir_rec(image, root, "/home/user/data/music");

it is included even containing "user/data" string. However, a possible "/home/user/data/music/user/data" is not added.

Usual wildcards, such as * or ? are also supported, with the usual meaning as stated in "man 7 glob". For example

// to exclude backup text files iso_tree_add_exclude(image, "*.~");

Returns:
1 on success, < 0 on error

const char *  name,
mode_t  mode,
dev_t  dev,
IsoSpecial **  special 
)

As far as libisofs concerns, an special file is a block device, a character device, a FIFO (named pipe) or a socket. You can choose the specific kind of file you want to add by setting mode propertly (see man 2 stat).

Note that special files are only written to image when Rock Ridge extensions are enabled. Moreover, a special file is just a directory entry in the image tree, no data is written beyond that.

Owner and hidden atts are taken from parent. You can modify any of them later.

Parameters:
parent the dir where the new special file will be created
name name for the new special file. If a node with same name already exists on parent, this functions fails with ISO_NODE_NAME_NOT_UNIQUE.
mode file type and permissions for the new node. Note that you can't specify any kind of file here, only special types are allowed. i.e, S_IFSOCK, S_IFBLK, S_IFCHR and S_IFIFO are valid types; S_IFLNK, S_IFREG and S_IFDIR aren't.
dev device ID, equivalent to the st_rdev field in man 2 stat.
special place where to store a pointer to the newly created special file. No extra ref is addded, so you will need to call iso_node_ref() if you really need it. You can pass NULL in this parameter if you don't need the pointer.
Returns:
number of nodes in parent if success, < 0 otherwise Possible errors: ISO_NULL_POINTER, if parent, name or dest are NULL ISO_NODE_NAME_NOT_UNIQUE, a node with same name already exists ISO_WRONG_ARG_VALUE if you select a incorrect mode ISO_OUT_OF_MEM

node place where to store a pointer to the newly added file. No extra ref is addded, so you will need to call iso_node_ref() if you really need it. You can pass NULL in this parameter if you don't need the pointer.
Returns:
number of nodes in parent if success, < 0 otherwise Possible errors: ISO_NULL_POINTER, if image, parent or path are NULL ISO_NODE_NAME_NOT_UNIQUE, a node with same name already exists ISO_OUT_OF_MEM

This includes image import.

Parameters:
report pointer to a function that will be called just before a file will be added to the image. You can control whether the file will be in fact added or ignored.

uint32_t *  range_start,
uint32_t *  range_size,
uint32_t *  next_tag,
char  md5[16],
int  flag 
)

Check a data block whether it is a libisofs session checksum tag and eventually obtain its recorded parameters.

These tags get written after volume descriptors, directory tree and checksum array and can be detected without loading the image tree. One may start reading and computing MD5 at the suspected image session start and look out for a session tag on the fly. See doc/checksum.txt .

Parameters:
data A complete and aligned data block read from an ISO image session.
tag_type 0= no tag 1= session tag 2= superblock tag 3= tree tag 4= relocated 64 kB superblock tag (at LBA 0 of overwriteable media)
pos Returns the LBA where the tag supposes itself to be stored. If this does not match the data block LBA then the tag might be image data payload and should be ignored for image checksumming.
range_start Returns the block address where the session is supposed to start. If this does not match the session start on media then the image volume descriptors have been been relocated. A proper checksum will only emerge if computing started at range_start.
range_size Returns the number of blocks beginning at range_start which are covered by parameter md5.
next_tag Returns the predicted block address of the next tag. next_tag is valid only if not 0 and only with return values 2, 3, 4. With tag types 2 and 3, reading shall go on sequentially and the MD5 computation shall continue up to that address. With tag type 4, reading shall resume either at LBA 32 for the first session or at the given address for the session which is to be loaded by default. In both cases the MD5 computation shall be re-started from scratch.
md5 Returns 16 byte of MD5 checksum.
flag Bitfield for control purposes: bit0-bit7= tag type being looked for 0= any checksum tag 1= session tag 2= superblock tag 3= tree tag 4= relocated superblock tag
Returns:
0= not a checksum tag, return parameters are invalid 1= checksum tag found, return parameters are valid <0= error (return parameters are valid with error ISO_MD5_AREA_CORRUPTED but not trustworthy because the tag seems corrupted)

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 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 iso_lib_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. Creates an IsoWriteOpts for writing an image. You should set the options desired with the correspondent setters.

Options by default are determined by the selected profile. Fifo size is set by default to 2 MB.

Parameters:
opts Pointer to the location where the newly created IsoWriteOpts will be stored. You should free it with iso_write_opts_free() when no more needed.
profile Default profile for image creation. For now the following values are defined: ---> 0 [BASIC] No extensions are enabled, and ISO level is set to 1. Only suitable for usage for very old and limited systems (like MS-DOS), or by a start point from which to set your custom options. ---> 1 [BACKUP] POSIX compatibility for backup. Simple settings, ISO level is set to 3 and RR extensions are enabled. Useful for backup purposes. Note that ACL and xattr are not enabled by default. If you enable them, expect them not to show up in the mounted image. They will have to be retrieved by libisofs applications like xorriso. ---> 2 [DISTRIBUTION] Setting for information distribution. Both RR and Joliet are enabled to maximize compatibility with most systems. Permissions are set to default values, and timestamps to the time of recording.
Returns:
1 success, < 0 error
Since:
0.6.2
int iso_write_opts_set_aaip ( IsoWriteOpts opts,
int  enable 
)

Control writing of AAIP informations for ACL and xattr.

For importing ACL and xattr when inserting nodes from external filesystems (e.g. the local POSIX filesystem) see iso_image_set_ignore_aclea(). For loading of this information from images see iso_read_opts_set_no_aaip().

Parameters:
enable 1 = write AAIP information from nodes into the image 0 = do not write AAIP information into the image All other values are reserved.
Since:
0.6.14
int iso_write_opts_set_aaip_susp_1_10 ( IsoWriteOpts opts,
int  oldvers 
)

Write AAIP as extension according to SUSP 1.10 rather than SUSP 1.12.

I.e. without announcing it by an ER field and thus without the need to preceed the RRIP fields and the AAIP field by ES fields. This saves 5 to 10 bytes per file and might avoid problems with readers which dislike ER fields other than the ones for RRIP. On the other hand, SUSP 1.12 frowns on such unannounced extensions and prescribes ER and ES. It does this since the year 1994.

In effect only if above iso_write_opts_set_aaip() enables writing of AAIP.

Since:
0.6.14
int iso_write_opts_set_allow_deep_paths ( IsoWriteOpts opts,

This breaks ECMA-119 specification. Use with caution.

Since:
0.6.2
int iso_write_opts_set_allow_full_ascii ( IsoWriteOpts opts,
int  allow 
)

Allow all ASCII characters to be appear on an ISO-9660 filename.

Note that "/" and "\0" characters are never allowed, even in RR names. This breaks ECMA-119 specification. Use with caution.

Since:
0.6.2
int iso_write_opts_set_allow_longer_paths ( IsoWriteOpts opts,
int  allow 
)

Allow path in the ISO-9660 tree to have more than 255 characters.

This breaks ECMA-119 specification. Use with caution.

Since:
0.6.2
int iso_write_opts_set_allow_lowercase ( IsoWriteOpts opts,
int  allow 
)

Allow lowercase characters in ISO-9660 filenames.

By default, only uppercase characters, numbers and a few other characters are allowed. This breaks ECMA-119 specification. Use with caution.

Since:
0.6.2
int iso_write_opts_set_always_gmt ( IsoWriteOpts opts,
int  gmt 
)

Whether to always record timestamps in GMT.

By default, libisofs stores local time information on image. You can set this to always store timestamps converted to GMT. This prevents any discrimination of the timezone of the image preparer by the image reader.

It is useful if you want to hide your timezone, or you live in a timezone that can't be represented in ECMA-119. These are timezones with an offset from GMT greater than +13 hours, lower than -12 hours, or not a multiple of 15 minutes. 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).

Since:
0.6.2
int iso_write_opts_set_appendable ( IsoWriteOpts opts,
int  append 
)

Set the type of image creation in case there was already an existing image imported.

Libisofs supports two types of creation: stand-alone and appended.

A stand-alone image is an image that does not need the old image any more for being mounted by the operating system or imported by libisofs. It may be written beginning with byte 0 of optical media or disk file objects. There will be no distinction between files from the old image and those which have been added by the new image generation.

On the other side, an appended image is not self contained. It may refer to files that stay stored in the imported existing image. This usage model is inspired by CD multi-session. It demands that the appended image is finally written to the same media resp. disk file as the imported image at an address behind the end of that imported image. The exact address may depend on media peculiarities and thus has to be announced by the application via iso_write_opts_set_ms_block(). The real address where the data will be written is under control of the consumer of the struct burn_source which takes the output of libisofs image generation. It may be the one announced to libisofs or an intermediate one. Nevertheless, the image will be readable only at the announced address.

If you have not imported a previous image by iso_image_import(), then the image will always be a stand-alone image, as there is no previous data to refer to.

Parameters:
append 1 to create an appended image, 0 for an stand-alone one.

int iso_write_opts_set_fifo_size ( IsoWriteOpts opts,
size_t  fifo_size 
)

Set the size, in number of blocks, of the FIFO buffer used between the writer thread and the burn_source.

You have to provide at least a 32 blocks buffer. Default value is set to 2MB, if that is ok for you, you don't need to call this function.

Since:
0.6.2
int iso_write_opts_set_hardlinks ( IsoWriteOpts opts,
int  enable 
)

Control generation of non-unique inode numbers for the emerging image.

Inode numbers get written as "file serial number" with PX entries as of RRIP-1.12. They may mark families of hardlinks. RRIP-1.10 prescribes a PX entry without file serial number. If not overriden by iso_write_opts_set_rrip_1_10_px_ino() there will be no file serial written into RRIP-1.10 images.

Inode number generation does not affect IsoNode objects which imported their inode numbers from the old ISO image (see iso_read_opts_set_new_inos()) and which have not been altered since import. It rather applies to IsoNode objects which were newly added to the image, or to IsoNode which brought no inode number from the old image, or to IsoNode where certain properties have been altered since image import.

If two IsoNode are found with same imported inode number but differing properties, then one of them will get assigned a new unique inode number. I.e. the hardlink relation between both IsoNode objects ends.

Parameters:
enable 1 = Collect IsoNode objects which have identical data sources and properties. 0 = Generate unique inode numbers for all IsoNode objects which do not have a valid inode number from an imported ISO image. All other values are reserved.
Since:
0.6.20
int iso_write_opts_set_iso1999 ( IsoWriteOpts opts,
int  enable 
)

Whether to use newer ISO-9660:1999 version.

This is the second version of ISO-9660. It allows longer filenames and has less restrictions than old ISO-9660. However, nobody is using it so there are no much reasons to enable this.

Since:
0.6.2
int iso_write_opts_set_iso_level ( IsoWriteOpts opts,
int  level 
)

Set the ISO-9960 level to write at.

Parameters:
level -> 1 for higher compatibility with old systems. With this level filenames are restricted to 8.3 characters. -> 2 to allow up to 31 filename characters. -> 3 to allow files greater than 4GB
Returns:
1 success, < 0 error
Since:
0.6.2
int iso_write_opts_set_joliet ( IsoWriteOpts opts,
int  enable 
)

Whether to add the non-standard Joliet extension to the image.

This extensions are heavily used in Microsoft Windows systems, so if you plan to use your disc on such a system you should add this extension. Usage of Joliet supplies longer filesystem length (up to 64 unicode characters), and deeper directory structure.

Parameters:
enable 1 to enable Joliet extension, 0 to not add them
Returns:
1 success, < 0 error
Since:
0.6.2
int iso_write_opts_set_joliet_longer_paths ( IsoWriteOpts opts,

This breaks Joliet specification. Use with caution.

Since:
0.6.2
int iso_write_opts_set_max_37_char_filenames ( IsoWriteOpts opts,
int  allow 
)

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. This breaks ECMA-119 specification and could lead to buffer overflow problems on old systems. Use with caution.

Since:
0.6.2
int iso_write_opts_set_ms_block ( IsoWriteOpts opts,
uint32_t  ms_block 
)

Set the start block of the image.

It is supposed to be the lba where the first block of the image will be written on disc. All references inside the ISO image will take this into account, thus providing a mountable image.

For appendable images, that are written to a new session, you should pass here the lba of the next writable address on disc.

In stand alone images this is usually 0. However, you may want to provide a different ms_block if you don't plan to burn the image in the first session on disc, such as in some CD-Extra disc whether the data image is written in a new session after some audio tracks.

Since:
0.6.2
int iso_write_opts_set_no_force_dots ( IsoWriteOpts opts,
int  no 
)

ISO-9660 forces filenames to have a ".", that separates file name from extension.

libisofs adds it if original filename doesn't has one. Set this to 1 to prevent this behavior. This breaks ECMA-119 specification. Use with caution.

Parameters:
no bit0= no forced dot with ECMA-119 bit1= no forced dot with Joliet (
Since:
0.6.30)
0.6.2
int iso_write_opts_set_omit_version_numbers ( IsoWriteOpts opts,
int  omit 
)

Omit the version number (";1") at the end of the ISO-9660 identifiers.

This breaks ECMA-119 specification, but version numbers are usually not used, so it should work on most systems. Use with caution.

Parameters:
omit bit0= omit version number with ECMA-119 and Joliet bit1= omit version number with Joliet alone (
Since:
0.6.30)
0.6.2
int iso_write_opts_set_output_charset ( IsoWriteOpts opts,
const char *  charset 
)

Set the charset to use for the RR names of the files that will be created on the image.

NULL to use default charset, that is the locale charset. You can obtain the list of charsets supported on your system executing "iconv -l" in a shell.

Since:
0.6.2
int iso_write_opts_set_overwrite_buf ( IsoWriteOpts opts,
uint8_t *  overwrite 
)

Sets the buffer where to store the descriptors which shall to be written at the beginning of an overwriteable media to point to the newly written image.

This is needed if the write start address of the image is not 0. In this case the first 64 KiB of the media have to be overwritten by the buffer content after the session was written and the buffer was updated by libisofs. Otherwise the new session would not be found by operating system function mount() or by libisoburn. (One could still mount that session if its start address is known.)

If you do not need this information, for example because you are creating a new image for LBA 0 or because you will create an image for a true multisession media, just do not use this call or set buffer to NULL.

Use cases:

  • Together with iso_write_opts_set_appendable(opts, 1) the buffer serves for the growing of an image as done in growisofs by Andy Polyakov. This allows appending of a new session to non-multisession media, such as DVD+RW. The new session will refer to the data of previous sessions on the same media. libisoburn emulates multisession appendability on overwriteable media and disk files by performing this use case.
  • Together with iso_write_opts_set_appendable(opts, 0) the buffer allows to write the first session on overwriteable media to start addresses other than 0. libisoburn in most cases writes the first session on overwriteable media and disk files to LBA 32 in order to preserve its descriptors from the subsequent overwriting by the descriptor buffer of later sessions.
Parameters:
buffer When not NULL, it should point to at least 64KiB of memory, where libisofs will install the contents that shall be written at the beginning of overwriteable media. You should initialize the buffer either with 0s, or with the contents of the first 32 blocks of the image you are growing. In most cases, 0 is good enought.

int iso_write_opts_set_pvd_times ( IsoWriteOpts opts,
time_t  vol_creation_time,
time_t  vol_modification_time,
time_t  vol_expiration_time,
time_t  vol_effective_time,
char *  vol_uuid 
)

Explicitely set the four timestamps of the emerging Primary Volume Descriptor.

Default with all parameters is 0. ECMA-119 defines them as:

Parameters:
vol_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.
vol_modification_time When "the information in the volume was last modified." A value of 0 means that the timepoint of write start is to be used.
vol_expiration_time When "the information in the volume may be regarded as obsolete." A value of 0 means that the information never shall expire.
vol_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_creation_time and 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. Other than with vol_*_time the resulting string in the ISO image is fully predictable and free of timezone pitfalls. It should express a reasonable time in form YYYYMMDDhhmmsscc E.g.: "2010040711405800" = 7 Apr 2010 11:40:58 (+0 centiseconds)
Since:
0.6.30
int iso_write_opts_set_record_md5 ( IsoWriteOpts opts,
int  session,
int  files 
)

Whether to compute and record MD5 checksums for the whole session and/or for each single IsoFile object.

The checksums represent the data as they were written into the image output stream, not necessarily as they were on hard disk at any point of time. See also calls iso_image_get_session_md5() and iso_file_get_md5().

Parameters:
opts The option set to be manipulated.
session If bit0 set: Compute session checksum
files If bit0 set: Compute a checksum for each single IsoFile object which gets its data content written into the session. Copy checksums from files which keep their data in older sessions. If bit1 set: Check content stability (only with bit0). I.e. before writing the file content into to image stream, read it once and compute a MD5. Do a second reading for writing into the image stream. Afterwards compare both MD5 and issue a MISHAP event ISO_MD5_STREAM_CHANGE if they do not match. Such a mismatch indicates content changes between the time point when the first MD5 reading started and the time point when the last block was read for writing. So there is high risk that the image stream was fed from changing and possibly inconsistent file content.

int iso_write_opts_set_relaxed_vol_atts ( IsoWriteOpts opts,

int iso_write_opts_set_replace_mode ( IsoWriteOpts opts,
int  dir_mode,
int  file_mode,
int  uid,
int  gid 
)

Whether to set default values for files and directory permissions, gid and uid.

All these take one of three values: 0, 1 or 2.

If 0, the corresponding attribute will be kept as set in the IsoNode. Unless you have changed it, it corresponds to the value on disc, so it is suitable for backup purposes. If set to 1, the corresponding attrib. will be changed by a default suitable value. Finally, if you set it to 2, the attrib. will be changed with the value specified by the functioins below. Note that for mode attributes, only the permissions are set, the file type remains unchanged.

int iso_write_opts_set_rockridge ( IsoWriteOpts opts,
int  enable 
)

Whether to use or not Rock Ridge extensions.

This are standard extensions to ECMA-119, intended to add POSIX filesystem features to ECMA-119 images. Thus, usage of this flag is highly recommended for images used on GNU/Linux systems. With the usage of RR extension, the resulting image will have long filenames (up to 255 characters), deeper directory structure, POSIX permissions and owner info on files and directories, support for symbolic links or special files... All that attributes can be modified/setted with the appropiate function.

Parameters:
enable 1 to enable RR extension, 0 to not add them
Returns:

Write field PX with file serial number (i.e.

inode number) even if iso_write_opts_set_rrip_version_1_10(,1) is in effect. This clearly violates the RRIP-1.10 specs. But it is done by mkisofs since a while and no widespread protest is visible in the web. If this option is not enabled, then iso_write_opts_set_hardlinks() will only have an effect with iso_write_opts_set_rrip_version_1_10(,0).

int iso_write_opts_set_rrip_version_1_10 ( IsoWriteOpts opts,
int  oldvers 
)

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.

Since:
0.6.12
int iso_write_opts_set_scdbackup_tag ( IsoWriteOpts opts,
char *  name,
char *  timestamp,
char *  tag_written 
)

Set the 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 iso_write_opts_set_ms_block()). 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.

Parameters:
name A word of up to 80 characters. Typically <volno>_<totalno> telling that this is volume <volno> of a total of <totalno> volumes.
timestamp A string of 13 characters YYMMDD.hhmmss (e.g. A90831.190324). 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 indicates success, <0 is error

Parameters:
ziso_count Will return the number of currently installed compression filters.
osiz_count Will return the number of currently installed uncompression filters.
flag Bitfield for control purposes, unused yet, submit 0
Returns:
1 on success, <0 on error
Since:

int iso_zisofs_set_params ( struct iso_zisofs_ctrl params,
int  flag 
)

Set the global parameters for zisofs filtering.

This is only allowed while no zisofs compression filters are installed. i.e. ziso_count returned by iso_zisofs_get_refcounts() has to be 0.

Parameters:
params Pointer to a structure with the intended settings.
flag Bitfield for control purposes, unused yet, submit 0
Returns:
1 on success, <0 on error
