Function Documentation

int burn_abort ( int  patience,
int(*)(void *handle, int patience, int elapsed)  pacifier_func,
void *  handle 
)

Abort any running drive operation and finally call burn_finish().

You MUST calm down the busy drive if an aborting event occurs during a burn run. For that you may call this function either from your own signal handling code or indirectly by activating the builtin signal handling: burn_set_signal_handling("my_app_name : ", NULL, 0); Else you may eventually call burn_drive_cancel() on the active drive and wait for it to assume state BURN_DRIVE_IDLE.

Parameters:
patience Maximum number of seconds to wait for drives to finish
pacifier_func If not NULL: a function to produce appeasing messages. See burn_abort_pacifier() for an example.
Returns:
1 ok, all went well 0 had to leave a drive in unclean state <0 severe error, do no use libburn again

int burn_abort_pacifier ( void *  handle,
int  patience,
int  elapsed 
)

A pacifier function suitable for burn_abort.

Parameters:
handle If not NULL, a pointer to a text suitable for printf("%s")
patience Maximum number of seconds to wait
elapsed Elapsed number of seconds

int burn_disc_add_session ( struct burn_disc *  d,
struct burn_session *  s,
unsigned int  pos 
)

Add a session to a disc at a specific position, increasing the sessions's reference count.

Parameters:
d Disc to add the session to
s Session to add to the disc
pos position to add at (BURN_POS_END is "at the end")
Returns:
0 for failure, 1 for success

struct burn_disc* burn_disc_create ( void   )  [read]

Create a new disc (for DAO recording).

Referenced by libburner_payload().

int burn_disc_erasable ( struct burn_drive *  d  ) 

Tells whether a disc can be erased or not.

Returns:
Non-zero means erasable

Referenced by libburner_blank_disc(), and libburner_payload().

void burn_disc_erase ( struct burn_drive *  drive,
int  fast 
)

Erase a disc in the drive.

The drive must be grabbed successfully BEFORE calling this functions. Always ensure that the drive reports a status of BURN_DISC_FULL before calling this function. An erase operation is not cancellable, as control of the operation is passed wholly to the drive and there is no way to interrupt it safely.

Parameters:
drive The drive with which to erase a disc.
fast Nonzero to do a fast erase, where only the disc's headers are erased; zero to erase the entire disc.

Referenced by libburner_blank_disc().

void burn_disc_free ( struct burn_disc *  d  ) 

Delete disc and decrease the reference count on all its sessions.

Parameters:
d The disc to be freed

int burn_disc_get_sectors ( struct burn_disc *  d  ) 

struct burn_session** burn_disc_get_sessions ( struct burn_disc *  d,
int *  num 
) [read]

Gets an array of all the sessions for the disc THIS IS NO LONGER VALID AFTER YOU ADD OR REMOVE A SESSION.

num Returns the number of sessions in the array
Returns:
array of sessions

enum burn_disc_status burn_disc_get_status ( struct burn_drive *  drive  ) 

Returns what kind of disc a drive is holding.

This function may need to be called more than once to get a proper status from it. See burn_disc_status for details.

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

Referenced by libburner_blank_disc(), and libburner_payload().

int burn_disc_pretend_blank ( struct burn_drive *  drive  ) 

WARNING: This revives an old bug-like behavior that might be dangerous.

Sets the drive status to BURN_DISC_BLANK if it is BURN_DISC_UNREADY or BURN_DISC_UNSUITABLE. Thus marking media as writable which actually failed to declare themselves either blank or (partially) filled.

Returns:
1 drive status has been set , 0 = unsuitable drive status

int burn_disc_pretend_full ( struct burn_drive *  drive  ) 

WARNING: This overrides the safety measures against unsuitable media.

Sets the drive status to BURN_DISC_FULL if it is BURN_DISC_UNREADY or BURN_DISC_UNSUITABLE. Thus marking media as blankable which actually failed to declare themselves either blank or (partially) filled.

void burn_disc_read ( struct burn_drive *  drive,
const struct burn_read_opts *  o 
)

Read a disc from the drive and write it to an fd pair.

The drive must be grabbed successfully BEFORE calling this function. Always ensure that the drive reports a status of BURN_DISC_FULL before calling this function.

Parameters:
drive The drive from which to read a disc.
o The options for the read operation.

int burn_disc_read_atip ( struct burn_drive *  drive  ) 

Reads ATIP information from inserted media.

To be obtained via burn_drive_get_write_speed(), burn_drive_get_min_write_speed(), burn_drive_get_start_end_lba(). The drive must be grabbed for this call.

int  trackno,
int *  lba,
int *  nwa 
)

Read start lba and Next Writeable Address of a track from media.

Usually a track lba is obtained from the result of burn_track_get_entry(). This call retrieves an updated lba, eventual nwa, and can address the invisible track to come. The drive must be grabbed for this call. One may not issue this call during ongoing burn_disc_write() or burn_disc_erase().

Parameters:
d The drive to query.
o If not NULL: write parameters to be set on drive before query
trackno 0=next track to come, >0 number of existing track

Parameters:
drive_info pointer to a single element out of the array obtained from burn_drive_scan() : &(drive_infos[driveno])
force controls degree of permissible drive usage at the moment this function is called, and the amount of automatically provided drive shutdown : 0= drive must be ungrabbed and BURN_DRIVE_IDLE 1= try to release drive resp. accept BURN_DRIVE_GRABBING Use these two only.

int *  channel_no,
int *  target_no,
int *  lun_no 
)

Try to obtain bus,host,channel,target,lun from path.

If there is an SCSI address at all, then this call should succeed with a persistent drive address obtained via burn_drive_get_adr(). It is also supposed to succeed with any device file of a (possibly emulated) SCSI device.

Returns:
1 = success , 0 = failure , -1 = severe error

void burn_drive_release ( struct burn_drive *  drive,
int  eject 
)

Release a drive.

This should not be done until the drive is no longer busy (see burn_drive_get_status). The drive is (O_EXCL) unlocked afterwards.

Parameters:
drive The drive to release.
eject Nonzero to make the drive eject the disc in it.

Referenced by libburner_regrab(), and main().

int burn_drive_scan ( struct burn_drive_info drive_infos[],
unsigned int *  n_drives 
)

Scan for drives.

This function MUST be called until it returns nonzero. No drives may be in use when this is called. All drive pointers are invalidated by using this function. Do NOT store drive pointers across calls to this function or death AND pain will ensue. After this call all drives depicted by the returned array are subject to eventual (O_EXCL) locking. See burn_preset_device_open(). This state ends either with burn_drive_info_forget() or with burn_drive_release(). It is unfriendly to other processes on the system to hold drives locked which one does not definitely plan to use soon.

Parameters:
drive_infos Returns an array of drive info items (cdroms/burners). The returned array must be freed by burn_drive_info_free() before burn_finish(), and also before calling this function burn_drive_scan() again.
n_drives Returns the number of drive items in drive_infos.
Returns:
0 while scanning is not complete >0 when it is finished sucessfully, <0 when finished but failed.

Referenced by libburner_aquire_by_driveno().

int burn_drive_scan_and_grab ( struct burn_drive_info drive_infos[],
char *  adr,
int  load 
)

Aquire a drive with known persistent address.This is the sysadmin friendly way to open one drive and to leave all others untouched.

It bundles the following API calls to form a non-obtrusive way to use libburn: burn_drive_add_whitelist() , burn_drive_scan() , burn_drive_grab() You are *strongly urged* to use this call whenever you know the drive address in advance. If not, then you have to use directly above calls. In that case, you are strongly urged* to drop any unintended drive which will be exclusively occupied and not closed by burn_drive_scan(). This can be done by shutting down the library including a call to burn_finish(). You may later start a new libburn session and should then use the function described here with an address obtained after burn_drive_scan() via burn_drive_get_adr(&(drive_infos[driveno]), adr) . Another way is to drop the unwanted drives by burn_drive_info_forget().

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 it is no longer needed, and before calling a scan function again. This is a result from call burn_drive_scan(). See there. Use with driveno 0 only.
adr The persistent address of the desired drive. Either obtained by burn_drive_get_adr() or guessed skillfully by application resp. its user.
load Nonzero to make the drive attempt to load a disc (close its tray door, etc).
Returns:
1 = success , 0 = drive not found , -1 = other error

Creates a data source for an image file (a track) from an open readable filedescriptor, an eventually open readable subcodes file descriptor and eventually a fixed size in bytes.

Parameters:
datafd The source of data.
subfd The eventual source for subcodes. Not used if -1.
size The eventual fixed size of eventually both fds. If this value is 0, the size will be determined from datafd.

Shutdown the library.

This should be called before exiting your application. Make sure that all drives you have grabbed are released before calling this.

Referenced by main().

int burn_initialize ( void   ) 

Initialize the library.

This must be called before using any other functions in the library. It may be called more than once with no effect. It is possible to 'restart' the library by shutting it down and re-initializing it. This is necessary if you follow the older and more general way of accessing a drive via burn_drive_scan() and burn_drive_grab(). See burn_drive_scan_and_grab() with its strong urges and its explanations.

Returns:
Nonzero if the library was able to initialize; zero if initialization failed.

int burn_msgs_obtain ( char *  minimum_severity,
int *  error_code,
char  msg_text[],
int *  os_errno,
char  severity[] 
)

Obtain the oldest pending libburn message from the queue which has at least the given minimum_severity.

This message and any older message of lower severity will get discarded from the queue and is then lost forever. Severity may be one of "NEVER", "FATAL", "SORRY", "WARNING", "HINT", "NOTE", "UPDATE", "DEBUG", "ALL". To call with minimum_severity "NEVER" will discard the whole queue.

Parameters:
error_code Will become a unique error code as liste in libburn/libdax_msgs.h
msg_text Must provide at least BURN_MSGS_MESSAGE_LEN bytes.
os_errno Will become the eventual errno related to the message

void burn_preset_device_open ( int  exclusive,
int  blocking,
int  abort_on_busy 
)

Set parameters for behavior on opening device files.

To be called early after burn_initialize() and before any bus scan. But not mandatory at all. Parameter value 1 enables a feature, 0 disables. Default is (1,0,0). Have a good reason before you change it.

Parameters:
exclusive 1 = Try to open only devices which are not marked as busy and try to mark them busy if opened sucessfully. (O_EXCL) There are kernels which simply don't care about O_EXCL. Some have it off, some have it on, some are switchable. 2 = in case of a SCSI device, also try to open exclusively the matching /dev/sr, /dev/scd and /dev/st . 0 = no attempt to make drive access exclusive.
blocking Try to wait for drives which do not open immediately but also do not return an error as well. (O_NONBLOCK) This might stall indefinitely with /dev/hdX hard disks.
abort_on_busy Unconditionally abort process when a non blocking exclusive opening attempt indicates a busy drive. Use this only after thorough tests with your app.
