Detailed Description

Define Documentation
#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.
For compatibility with good ol' paranoia
#define paranoia_free cdio_paranoia_free |
#define paranoia_init cdio_paranoia_init |
#define paranoia_modeset cdio_paranoia_modeset |
#define paranoia_overlapset cdio_paranoia_overlapset |
#define paranoia_read cdio_paranoia_read |
#define paranoia_read_limited cdio_paranoia_read_limited |
#define paranoia_seek cdio_paranoia_seek |
#define paranoia_set_range cdio_paranoia_set_range |
Enumeration Type Documentation
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
|
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
Free any resources associated with p.
- Parameters:
-
| p | paranoia object to for which resources are to be freed. |
- See also:
- paranoia_init.
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
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 |
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.
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.
- See also:
- cdio_paranoia_read.
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. |

Variable Documentation
The below variables are trickery to force the above enum symbol values to be recorded in debug symbol tables. They are used to allow one to refer to the enumeration value names in the typedefs above in a debugger and debugger expressions
