Define Documentation

#define CDIO_MAX_DEVICE_DRIVER   DRIVER_WIN32

#define CDIO_MAX_DRIVER   DRIVER_NRG

#define CDIO_MIN_DEVICE_DRIVER   CDIO_MIN_DRIVER

Make sure what's listed for CDIO_MIN_DRIVER is the last enumeration in driver_id_t. Since we have a bogus (but useful) 0th entry above we don't have to add one.

Size of fields returned by an INQUIRY command Enumerator: CDIO_MMC_HW_VENDOR_LEN  length of vendor field CDIO_MMC_HW_MODEL_LEN  length of model field CDIO_MMC_HW_REVISION_LEN  length of revision field

enum cdio_src_category_mask_t

Flags specifying the category of device to open or is opened. Enumerator: CDIO_SRC_IS_DISK_IMAGE_MASK  Read source is a CD image. CDIO_SRC_IS_DEVICE_MASK  Read source is a CD device. CDIO_SRC_IS_SCSI_MASK  Read source SCSI device. CDIO_SRC_IS_NATIVE_MASK

enum driver_id_t

The driver_id_t enumerations may be used to tag a specific driver that is opened or is desired to be opened. Note that this is different than what is available on a given host. Order is a little significant since the order is used in scans. Also the enumeration values are assumed not to leave any holes so we can use ++ to iterate over values. We have to start with DRIVER_UNKNOWN and devices should come before disk-image readers. By putting something towards the top (a lower enumeration number), in an iterative scan we prefer that to something with a higher enumeration number. NOTE: IF YOU MODIFY ENUM MAKE SURE INITIALIZATION IN CDIO.C AGREES. Enumerator: DRIVER_UNKNOWN  Used as input when we don't care what kind of driver to use. DRIVER_AIX  AIX driver DRIVER_BSDI  BSDI driver DRIVER_FREEBSD  FreeBSD driver - includes CAM and ioctl access DRIVER_LINUX  GNU/Linux Driver DRIVER_SOLARIS  Sun Solaris Driver DRIVER_OSX  Apple OSX Driver DRIVER_WIN32  Microsoft Windows Driver. Includes ASPI and ioctl acces. DRIVER_CDRDAO  cdrdao format CD image. This is listed before BIN/CUE, to make the code prefer cdrdao over BIN/CUE when both exist. DRIVER_BINCUE  CDRWIN BIN/CUE format CD image. This is listed before NRG, to make the code prefer BIN/CUE over NRG when both exist. DRIVER_NRG  Nero NRG format CD image. DRIVER_DEVICE  Is really a set of the above; should come last

enum driver_return_code_t

The following are status codes for completion of a given cdio operation. By design 0 is successful completion and -1 is error completion. This is compatable with ioctl so those routines that call ioctl can just pass the value the get back (cast as this enum). Also, by using negative numbers for errors, the enumeration values below can be used in places where a positive value is expected when things complete successfully. For example, get_blocksize returns the blocksize, but on error uses the error codes below. So note that this enumeration is often cast to an integer. C seems to tolerate this. Enumerator: DRIVER_OP_SUCCESS  in cases where an int is returned, like cdio_set_speed, more the negative return codes are for errors and the positive ones for success. DRIVER_OP_ERROR  operation returned an error DRIVER_OP_UNSUPPORTED  returned when a particular driver doesn't support a particular operation. For example an image driver which doesn't really "eject" a CD. DRIVER_OP_UNINIT  returned when a particular driver hasn't been initialized or a null pointer has been passed. DRIVER_OP_NOT_PERMITTED  Operation not permitted. For example might be a permission problem. DRIVER_OP_BAD_PARAMETER  Bad parameter passed DRIVER_OP_BAD_POINTER  Bad pointer to memory area DRIVER_OP_NO_DRIVER  Operaton called on a driver not available on this OS

NULL is returned on error or there is no CD-ROM device. In some situations of drivers or OS's we can't find a CD device if there is no media in it and it is possible for this routine to return NULL even though there may be a hardware CD-ROM. See also: cdio_open_cd, cdio_open

char* cdio_get_default_device_nrg (  void   )

Get a string containing the default device name that the NRG driver would use when none is specified. A scan is made for NRG disk images in the current directory. Returns: string containing the default device. NULL on error or there is no CD-ROM device.

See also: cdio_open_cd, cdio_open

char* cdio_get_default_device_win32 (  void   )

Return a string containing the default device name that the Win32 driver would use when none is specified. A scan is made for CD-ROM drives with CDs in them. In some situations of drivers or OS's we can't find a CD device if there is no media in it and it is possible for this routine to return NULL even though there may be a hardware CD-ROM. See also: cdio_open_cd, cdio_open

char** cdio_get_devices (  driver_id_t  driver_id  )

Return an array of device names. If you want a specific devices for a driver, give that device. If you want hardware devices, give DRIVER_DEVICE and if you want all possible devices, image drivers and hardware drivers give DRIVER_UNKNOWN. NULL is returned if we couldn't return a list of devices. In some situations of drivers or OS's we can't find a CD device if there is no media in it and it is possible for this routine to return NULL even though there may be a hardware CD-ROM.

char** cdio_get_devices_aix (  void   )

char** cdio_get_devices_bincue (  void   )

char** cdio_get_devices_bsdi (  void   )

char** cdio_get_devices_ret (  driver_id_t *  p_driver_id  )

Like cdio_get_devices, but we may change the p_driver_id if we were given DRIVER_DEVICE or DRIVER_UNKNOWN. This is because often one wants to get a drive name and then *open* it afterwards. Giving the driver back facilitates this, and speeds things up for libcdio as well.

Return a list of all of the CD-ROM devices that the Solaris driver can find.

char** cdio_get_devices_win32 (  void   )

char** cdio_get_devices_with_cap (  char *  ppsz_search_devices[], cdio_fs_anal_t  capabilities, bool  b_any )

Get an array of device names in search_devices that have at least the capabilities listed by the capabities parameter. If search_devices is NULL, then we'll search all possible CD drives. Capabilities have two parts to them, a "filesystem" part and an "analysis" part. The filesystem part is mutually exclusive. For example either the filesystem is at most one of the High-Sierra, UFS, or HFS, ISO9660, fileystems. Valid combinations of say HFS and ISO9660 are specified as a separate "filesystem". Capabilities on the other hand are not mutually exclusive. For example a filesystem may have none, either, or both of the XA or Rock-Ridge extension properties. If "b_any" is set false then every capability listed in the analysis portion of capabilities (i.e. not the basic filesystem) must be satisified. If no analysis capabilities are specified, that's a match. If "b_any" is set true, then if any of the analysis capabilities matches, we call that a success. In either case, in the filesystem portion different filesystem either specify 0 to match any filesystem or the specific filesystem type. To find a CD-drive of any type, use the mask CDIO_FS_MATCH_ALL. Returns: the array of device names or NULL if we couldn't get a default device. It is also possible to return a non NULL but after dereferencing the the value is NULL. This also means nothing was found.

char** cdio_get_devices_with_cap_ret (  char *  ppsz_search_devices[], cdio_fs_anal_t  capabilities, bool  b_any, driver_id_t *  p_driver_id )

Like cdio_get_devices_with_cap but we return the driver we found as well. This is because often one wants to search for kind of drive and then *open* it afterwards. Giving the driver back facilitates this, and speeds things up for libcdio as well.

Variable Documentation

const driver_id_t cdio_os_driver

There will generally be only one hardware for a given build/platform from the list above. You can use the variable below to determine which you've got. If the build doesn't make an hardware driver, then the value will be DRIVER_UNKNOWN.

cdio_drive_cap_misc_t debug_cdio_drive_cap_misc

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.
