Typedef Documentation

typedef struct iso_extension_record_s iso_extension_record_t
 

typedef struct iso_rock_cl_s iso_rock_cl_t
 

Child link. See Section 4.1.5.1

typedef struct iso_rock_nm_s iso_rock_nm_t
 

typedef struct iso_rock_pl_s iso_rock_pl_t
 

Parent link. See Section 4.1.5.2

typedef struct iso_rock_pn_s iso_rock_pn_t
 

POSIX device number, PN. A PN is mandatory if the file type recorded in the "PX" File Mode field for a Directory Record indicates a character or block device (ISO_ROCK_ISCHR | ISO_ROCK_ISBLK). This entry is ignored for other (non-Direcotry) file types. No more than one "PN" is recorded in the System Use Area of a Directory Record.

See Rock Ridge Section 4.1.2

typedef struct iso_rock_px_s iso_rock_px_t
 

POSIX file attributes, PX. See Rock Ridge Section 4.1.2

typedef struct iso_rock_sf_s iso_rock_sf_t
 

File data in sparse format. See Rock Ridge Section 4.1.7

typedef struct iso_rock_sl_part_s iso_rock_sl_part_t
 

typedef struct iso_rock_sl_s iso_rock_sl_t
 

Symbolic link. See Rock Ridge Section 4.1.3

Enumeration Type Documentation

enum iso_rock_enums
 

An enumeration for some of the ISO_ROCK_* #defines below. This isn't really an enumeration one would really use in a program it is to be helpful in debuggers where wants just to refer to the ISO_ROCK_* names and get something.

Enumerator:
ISO_ROCK_IRUSR  read permission (owner)
ISO_ROCK_IWUSR  write permission (owner)
ISO_ROCK_IXUSR  execute permission (owner)
ISO_ROCK_IRGRP  read permission (group)
ISO_ROCK_IWGRP  write permission (group)
ISO_ROCK_IXGRP  execute permission (group)
ISO_ROCK_IROTH  read permission (other)
ISO_ROCK_IWOTH  write permission (other)
ISO_ROCK_IXOTH  execute permission (other)
ISO_ROCK_ISUID  set user ID on execution
ISO_ROCK_ISGID  set group ID on execution
ISO_ROCK_ISVTX  save swapped text even after use
ISO_ROCK_ISSOCK  socket
ISO_ROCK_ISLNK  symbolic link
ISO_ROCK_ISREG  regular
ISO_ROCK_ISBLK  block special
ISO_ROCK_ISCHR  character special
ISO_ROCK_ISDIR  directory
ISO_ROCK_ISFIFO  pipe or FIFO

enum iso_rock_nm_flag_t
 

These are the bits and their meanings for flags in the NM structure.

Enumerator:
ISO_ROCK_NM_CONTINUE 
ISO_ROCK_NM_CURRENT 
ISO_ROCK_NM_PARENT 

enum iso_rock_sl_flag_t
 

These are the bits and their meanings for flags in the SL structure.

Enumerator:
ISO_ROCK_SL_CONTINUE 
ISO_ROCK_SL_CURRENT 
ISO_ROCK_SL_PARENT 
ISO_ROCK_SL_ROOT 

enum iso_rock_tf_flag_t
 

These are the bits and their meanings for flags in the TF structure.

Enumerator:
ISO_ROCK_TF_CREATE 
ISO_ROCK_TF_MODIFY 
ISO_ROCK_TF_ACCESS 
ISO_ROCK_TF_ATTRIBUTES 
ISO_ROCK_TF_BACKUP 
ISO_ROCK_TF_EXPIRATION 
ISO_ROCK_TF_EFFECTIVE 
ISO_ROCK_TF_LONG_FORM 

Function Documentation

PRAGMA_END_PACKED int get_rock_ridge_filename (  iso9660_dir_t *  de,
char *  retname,
iso9660_stat_t *  p_stat
) 
 

return length of name field; 0: not found, -1: to be ignored

mode_t iso9660_get_posix_filemode_from_rock (  const iso_rock_statbuf_t *  rr  ) 
 

Returns POSIX mode bitstring for a given file.

const char* iso9660_get_rock_attr_str (  posix_mode_t  st_mode  ) 
 

Returns a string which interpreting the POSIX mode st_mode. For example: 

  drwxrws---
  -rw---Sr--
  lrwxrwxrwx

A description of the characters in the string follows The 1st character is either "d" if the entry is a directory, "l" is a symbolic link or "-" if neither.

The 2nd to 4th characters refer to permissions for a user while the the 5th to 7th characters refer to permissions for a group while, and the 8th to 10h characters refer to permissions for everyone.

In each of these triplets the first character (2, 5, 8) is "r" if the entry is allowed to be read.

The second character of a triplet (3, 6, 9) is "w" if the entry is allowed to be written.

The third character of a triplet (4, 7, 10) is "x" if the entry is executable but not user (for character 4) or group (for characters 6) settable and "s" if the item has the corresponding user/group set.

For a directory having an executable property on ("x" or "s") means the directory is allowed to be listed or "searched". If the execute property is not allowed for a group or user but the corresponding group/user is set "S" indicates this. If none of these properties holds the "-" indicates this.

These variables are not used, but are defined to facilatate debugging by letting us use enumerations values (which also correspond to #define's inside a debugged program.
