driver_id_t

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 should not be changed lightly because it breaks the ABI. One is not supposed to iterate over the values, but iterate over the cdio_drivers and cdio_device_drivers arrays.

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_FREEBSD	FreeBSD driver - includes CAM and ioctl access
DRIVER_NETBSD	NetBSD Driver.
DRIVER_LINUX	GNU/Linux Driver
DRIVER_SOLARIS	Sun Solaris Driver
DRIVER_OSX	Apple OSX (or MacOS) Driver
DRIVER_WIN32	Microsoft Windows Driver. Includes ASPI and ioctl access.
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

driver_return_code_t

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	Operation called on a driver not available on this OS
DRIVER_OP_MMC_SENSE_DATA	MMC operation returned sense data, but no other error above recorded.

cdio_get_devices_osx()

char** cdio_get_devices_osx

(

void

)

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

cdio_get_devices_ret()

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.

cdio_get_devices_solaris()

char** cdio_get_devices_solaris

(

void

)

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

cdio_get_devices_win32()

char** cdio_get_devices_win32

(

void

)

cdio_get_devices_with_cap()

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.

cdio_get_devices_with_cap_ret()

		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.
