Detailed Description

The top-level header for libcdda_paranoia: a device- and OS- independent library for reading CD-DA with error tolerance and repair. Applications include this for paranoia access.

Macro Definition Documentation

CD_FRAMEWORDS

#define CD_FRAMEWORDS   (CDIO_CD_FRAMESIZE_RAW/2)

Paranoia likes to work with 16-bit numbers rather than (possibly byte-swapped) bytes. So there are this many 16-bit numbers block (frame, or sector) read.

Enumeration Type Documentation

paranoia_cb_mode_t

enum paranoia_cb_mode_t

Flags set in a callback.

The enumeration type one probably wouldn't really use in a program. It is here instead of defines to give symbolic names that can be helpful in debuggers where wants just to say refer to PARANOIA_CB_READ and get the correct value.

Enumerator
PARANOIA_CB_READ	Read off adjust ???
PARANOIA_CB_VERIFY	Verifying jitter
PARANOIA_CB_FIXUP_EDGE	Fixed edge jitter
PARANOIA_CB_FIXUP_ATOM	Fixed atom jitter
PARANOIA_CB_SCRATCH	Unsupported
PARANOIA_CB_REPAIR	Unsupported
PARANOIA_CB_SKIP	Skip exhausted retry
PARANOIA_CB_DRIFT	Skip exhausted retry
PARANOIA_CB_BACKOFF	Unsupported
PARANOIA_CB_OVERLAP	Dynamic overlap adjust
PARANOIA_CB_FIXUP_DROPPED	Fixed dropped bytes
PARANOIA_CB_FIXUP_DUPED	Fixed duplicate bytes
PARANOIA_CB_READERR	Hard read error
PARANOIA_CB_CACHEERR	Bad cache management
PARANOIA_CB_WROTE	Wrote block "*"
PARANOIA_CB_FINISHED	Finished writing "*"

paranoia_mode_t

enum paranoia_mode_t

Flags used in paranoia_modeset.

The enumeration type one probably wouldn't really use in a program. It is here instead of defines to give symbolic names that can be helpful in debuggers where wants just to say refer to PARANOIA_MODE_DISABLE and get the correct value.

Enumerator
PARANOIA_MODE_DISABLE	No fixups
PARANOIA_MODE_VERIFY	Verify data integrety in overlap area
PARANOIA_MODE_FRAGMENT	unsupported
PARANOIA_MODE_OVERLAP	Perform overlapped reads
PARANOIA_MODE_SCRATCH	unsupported
PARANOIA_MODE_REPAIR	unsupported
PARANOIA_MODE_NEVERSKIP	Do not skip failed reads (retry maxretries)
PARANOIA_MODE_FULL	Maximum paranoia - all of the above (except disable)

Function Documentation

cdio_paranoia_cachemodel_size()

int cdio_paranoia_cachemodel_size ( cdrom_paranoia_t * p, int sectors )

extern

Set or query the number of sectors used for paranoia cache modelling.

Parameters

p	paranoia object
sectors	number of sectors to use, default is 1200 (pass -1 to query current model size without setting a new value)

Returns

number of cache sectors before the call

cdio_paranoia_free()

void cdio_paranoia_free ( cdrom_paranoia_t * p )

extern

Free any resources associated with p.

Parameters

p	paranoia object to for which resources are to be freed.

See also

paranoia_init.

cdio_paranoia_init()

cdrom_paranoia_t * cdio_paranoia_init ( cdrom_drive_t * d )

extern

Get and initialize a new cdrom_paranoia object from cdrom_drive. Run this before calling any of the other paranoia routines below.

Returns

new cdrom_paranoia object Call paranoia_free() when you are done with it

cdio_paranoia_modeset()

void cdio_paranoia_modeset ( cdrom_paranoia_t * p, int mode_flags )

extern

Set the kind of repair you want to on for reading. The modes are listed above

Parameters

p	paranoia type
mode_flags	paranoia mode flags built from values in paranoia_mode_t, e.g. PARANOIA_MODE_FULL^PARANOIA_MODE_NEVERSKIP

cdio_paranoia_overlapset()

void cdio_paranoia_overlapset ( cdrom_paranoia_t * p, long overlap )

extern

a temporary hack

cdio_paranoia_read()

int16_t * cdio_paranoia_read ( cdrom_paranoia_t * p, void(* callback )(long int, paranoia_cb_mode_t) )

extern

Reads the next sector of audio data and returns a pointer to a full sector of verified samples.

Parameters

p	paranoia object.
callback	callback routine which gets called with the status on each read.

Returns

the audio data read, CDIO_CD_FRAMESIZE_RAW (2352) bytes. This data is not to be freed by the caller. It will persist only until the next call to paranoia_read() for this p.

cdio_paranoia_read_limited()

int16_t * cdio_paranoia_read_limited ( cdrom_paranoia_t * p, void(* callback )(long int, paranoia_cb_mode_t), int max_retries )

extern

The same as cdio_paranoia_read but the number of retries is set.

Parameters

p	paranoia object.
callback	callback routine which gets called with the status on each read.
max_retries	number of times to try re-reading a block before failing.

Returns

the block of CDIO_FRAMEIZE_RAW bytes (or CDIO_FRAMESIZE_RAW / 2 16-bit integers). Unless byte-swapping has been turned off the 16-bit integers Endian independent order.

cdio_paranoia_seek()

lsn_t cdio_paranoia_seek ( cdrom_paranoia_t * p, int32_t seek, int whence )

extern

reposition reading offset.

Parameters

p	paranoia type
seek	byte offset to seek to
whence	like corresponding parameter in libc's lseek, e.g. SEEK_SET or SEEK_END.

cdio_paranoia_set_range()

void cdio_paranoia_set_range ( cdrom_paranoia_t * p, long int start, long int end )

extern

cdio_paranoia_version()
