Detailed Description

Common type definitions used pervasively in libcdio.


Define Documentation

#define __cd_offsetof (   TYPE,
  MEMBER 
)    ((size_t) &((TYPE *)0)->MEMBER)

our own offsetof()-like macro

#define bool   unsigned char
#define CDIO_INVALID_LBA   -45301

Constant for invalid LBA. It is 151 less than the most negative LBA -45150. This provide slack for the 150-frame offset in LBA to LSN 150 conversions

Constant for invalid LSN

#define CDIO_INVALID_SESSION   0xFF

Constant for invalid session number

#define CDIO_ISRC_SIZE   12

Number of ASCII bytes in International Standard Recording Codes (ISRC)

#define CDIO_MCN_SIZE   13

Number of ASCII bytes in a media catalog number (MCN). We include an extra 0 byte so these can be used as C strings.

#define false   0
#define GNUC_CONST
#define GNUC_FORMAT (   arg_idx)
#define GNUC_LIKELY (   x)    (x)
#define GNUC_NORETURN
#define GNUC_PRINTF (   format_idx,
  arg_idx 
)
#define GNUC_SCANF (   format_idx,
  arg_idx 
)
#define GNUC_UNLIKELY (   x)    (x)
#define GNUC_UNUSED
#define INT64_C (   c)    c ## LL
#define LIBCDIO_DEPRECATED (   object,
  notice 
)

Provide a notice for deprecated elements. Before gcc 4.5 'deprecated' takes no arguments.

#define msf_t_SIZEOF   3
#define NULL   ((void*) 0)
#define true   1
#define UINT16_C (   c)    c ## U
#define UINT32_C (   c)    c ## U
#define UINT64_C (   c)    c ## ULL

Typedef Documentation

typedef uint8_t bitfield_t
typedef int cdio_fs_anal_t
typedef char cdio_isrc_t[CDIO_ISRC_SIZE+1]

Type to hold ASCII bytes in a ISRC. We include an extra 0 byte so these can be used as C strings.

typedef char cdio_mcn_t[CDIO_MCN_SIZE+1]

Type to hold ASCII bytes in a media catalog number (MCN). We include an extra 0 byte so these can be used as C strings.

typedef char cdio_utf8_t

UTF-8 char definition.

Type to denote UTF-8 strings.

typedef int32_t lba_t

The type of a Logical Block Address. We allow for an lba to be negative to be consistent with an lba, although I'm not sure this this is possible.

typedef int32_t lsn_t

The type of a Logical Sector Number. Note that an lba can be negative and the MMC3 specs allow for a conversion of a negative lba.

msf_t
typedef typedefPRAGMA_END_PACKED struct msf_s msf_t
typedef uint8_t session_t

The type of a session number 0..99.

typedef uint8_t track_t

The type of a track number 0..99.

typedef uint8_t ubyte
