Detailed Description

Disk label access.

Most programs will need to use ped_disk_new() or ped_disk_new_fresh() to get anything done. A PedDisk is always associated with a device and has a partition table. There are different types of partition tables (or disk labels). These are represented by the PedDiskType enumeration.

Function Documentation

_ped_disk_alloc()

PedDisk * _ped_disk_alloc	(	const PedDevice *	dev,
		const PedDiskType *	type
	)

_ped_disk_free()

void _ped_disk_free

(

PedDisk *

disk

)

ped_disk_add_partition()

int ped_disk_add_partition	(	PedDisk *	disk,
		PedPartition *	part,
		const PedConstraint *	constraint
	)

Adds PedPartition part to PedDisk disk.

Warning

The partition's geometry may be changed, subject to constraint. You could set constraint to ped_constraint_exact(&part->geom), but many partition table schemes have special requirements on the start and end of partitions. Therefore, having an overly strict constraint will probably mean that this function will fail (in which case part will be left unmodified) part is assigned a number (part->num) in this process.

Returns

0 on failure.

ped_disk_check()

int ped_disk_check

(

const PedDisk *

disk

)

Perform a sanity check on a partition table.

Note

The check performed is generic (i.e. it does not depends on the label type of the disk.

Exceptions

PED_EXCEPTION_WARNING

if a partition type ID does not match the file system on it.

Returns

0 if the check fails, 1 otherwise.

ped_disk_clobber()

int ped_disk_clobber

(

PedDevice *

dev

)

Remove all identifying signatures of a partition table,.

Returns

0 on error, 1 otherwise.

See also

ped_disk_clobber()

ped_disk_commit()

int ped_disk_commit

(

PedDisk *

disk

)

ped_disk_commit_to_dev()

int ped_disk_commit_to_dev

(

PedDisk *

disk

)

Write the changes made to the in-memory description of a partition table to the device.

Returns

0 on failure, 1 otherwise.

ped_disk_commit_to_os()

int ped_disk_commit_to_os

(

PedDisk *

disk

)

Tell the operating system kernel about the partition table layout of disk.

This is rather loosely defined: for example, on old versions of Linux, it simply calls the BLKRRPART ioctl, which tells the kernel to reread the partition table. On newer versions (2.4.x), it will use the new blkpg interface to tell Linux where each partition starts/ends, etc. In this case, Linux does not need to have support for a specific type of partition table.

Returns

0 on failure, 1 otherwise.

ped_disk_delete_all()

int ped_disk_delete_all

(

PedDisk *

disk

)

Removes and destroys all partitions on disk.

Returns

0 on failure.

ped_disk_delete_partition()

int ped_disk_delete_partition	(	PedDisk *	disk,
		PedPartition *	part
	)

Removes part from disk, and destroys part.

Returns

0 on failure.

ped_disk_destroy()

void ped_disk_destroy

(

PedDisk *

disk

)

Close disk.

What this function does depends on the PedDiskType of disk, but you can generally assume that outstanding writes are flushed (this mainly means that _ped_disk_free is called).

ped_disk_duplicate()

PedDisk * ped_disk_duplicate

(

const PedDisk *

old_disk

)

Clone a PedDisk object.

Returns

Deep copy of old_disk, NULL on failure.

ped_disk_extended_partition()

PedPartition * ped_disk_extended_partition

(

const PedDisk *

disk

)

ped_disk_flag_get_by_name()

PedDiskFlag ped_disk_flag_get_by_name

(

const char *

name

)

Returns the flag associated with name.

name can be the English string, or the translation for the native language.

ped_disk_flag_get_name()

const char * ped_disk_flag_get_name

(

PedDiskFlag

flag

)

Returns a name for a flag, e.g.

PED_DISK_CYLINDER_ALIGNMENT will return "cylinder_alignment".

Note

The returned string will be in English. However, translations are provided, so the caller can call dgettext("parted", RESULT) on the result.

ped_disk_flag_next()

PedDiskFlag ped_disk_flag_next

(

PedDiskFlag

flag

)

Iterates through all disk flags.

ped_disk_flag_next(0) returns the first flag

Returns

the next flag, or 0 if there are no more flags

ped_disk_get_flag()

int ped_disk_get_flag	(	const PedDisk *	disk,
		PedDiskFlag	flag
	)

Get the state (1 or 0) of a flag on a disk.

ped_disk_get_last_partition_num()

int ped_disk_get_last_partition_num

(

const PedDisk *

disk

)

Get the highest available partition number on disk.

ped_disk_get_max_partition_geometry()

PedGeometry * ped_disk_get_max_partition_geometry	(	PedDisk *	disk,
		PedPartition *	part,
		const PedConstraint *	constraint
	)

Get the maximum geometry part can be grown to, subject to constraint.

Returns

NULL on failure.

ped_disk_get_max_primary_partition_count()

int ped_disk_get_max_primary_partition_count

(

const PedDisk *

disk

)

Get the maximum number of (primary) partitions the disk label supports.

For example, MacIntosh partition maps can have different sizes, and accordingly support a different number of partitions.

ped_disk_get_max_supported_partition_count()

bool ped_disk_get_max_supported_partition_count	(	const PedDisk *	disk,
		int *	supported
	)

Get the highest supported partition number on disk.

Returns

0 if call fails. 1 otherwise.

ped_disk_get_partition()

PedPartition * ped_disk_get_partition	(	const PedDisk *	disk,
		int	num
	)

Returns the partition numbered num.

Returns

NULL if the specified partition does not exist.

ped_disk_get_partition_alignment()

PedAlignment * ped_disk_get_partition_alignment

(

const PedDisk *

disk

)

Get the alignment needed for partition boundaries on this disk.

The returned alignment describes the alignment for the start sector of the partition, for all disklabel types which require alignment, except Sun disklabels, the end sector must be aligned too. To get the end sector alignment decrease the PedAlignment offset by 1.

Returns

NULL on error, otherwise a pointer to a dynamically allocated alignment.

ped_disk_get_partition_by_sector()

PedPartition * ped_disk_get_partition_by_sector	(	const PedDisk *	disk,
		PedSector	sect
	)

Returns the partition that contains sect.

If sect lies within a logical partition, then the logical partition is returned (not the extended partition).

ped_disk_get_primary_partition_count()

int ped_disk_get_primary_partition_count

(

const PedDisk *

disk

)

Get the number of primary partitions.

ped_disk_get_uuid()

uint8_t * ped_disk_get_uuid

(

const PedDisk *

disk

)

Get the uuid of the disk disk.

This will only work if the disk label supports it.

ped_disk_is_flag_available()

int ped_disk_is_flag_available	(	const PedDisk *	disk,
		PedDiskFlag	flag
	)

Check whether a given flag is available on a disk.

Returns

1 if the flag is available.

ped_disk_max_partition_length()

PedSector ped_disk_max_partition_length

(

const PedDisk *

disk

)

Return the maximum representable length (in sectors) of a partition on disk \disk.

ped_disk_max_partition_start_sector()

PedSector ped_disk_max_partition_start_sector

(

const PedDisk *

disk

)

Return the maximum representable start sector of a partition on disk \disk.

ped_disk_maximize_partition()

int ped_disk_maximize_partition	(	PedDisk *	disk,
		PedPartition *	part,
		const PedConstraint *	constraint
	)

Grow PedPartition part geometry to the maximum possible subject to constraint.

The new geometry will be a superset of the old geometry.

Returns

0 on failure

ped_disk_minimize_extended_partition()

int ped_disk_minimize_extended_partition

(

PedDisk *

disk

)

Reduce the size of the extended partition to a minimum while still wrapping its logical partitions.

If there are no logical partitions, remove the extended partition.

Returns

0 on failure.

ped_disk_new()

PedDisk * ped_disk_new

(

PedDevice *

dev

)

Read the partition table off a device (if one is found).

Warning

May modify dev->cylinders, dev->heads and dev->sectors if the partition table indicates that the existing values are incorrect.

Returns

A new PedDisk object; NULL on failure (e.g. partition table not detected).

ped_disk_new_fresh()

PedDisk * ped_disk_new_fresh	(	PedDevice *	dev,
		const PedDiskType *	type
	)

Create a new partition table on dev.

This new partition table is only created in-memory, and nothing is written to disk until ped_disk_commit_to_dev() is called.

Returns

The newly constructed PedDisk , NULL on failure.

ped_disk_next_partition()

PedPartition * ped_disk_next_partition	(	const PedDisk *	disk,
		const PedPartition *	part
	)

Return the next partition after part on disk.

If part is NULL, return the first partition. If part is the last partition, returns NULL. If part is an extended partition, returns the first logical partition. If this is called repeatedly passing the return value as part, a depth-first traversal is executed.

Returns

The next partition, NULL if no more partitions left.

ped_disk_print()

void ped_disk_print

(

const PedDisk *

disk

)

Prints a summary of disk's partitions.

Useful for debugging.

ped_disk_probe()

PedDiskType * ped_disk_probe

(

PedDevice *

dev

)

Return the type of partition table detected on "dev".

Returns

Type; NULL if none was detected.

ped_disk_remove_partition()

int ped_disk_remove_partition	(	PedDisk *	disk,
		PedPartition *	part
	)

Removes PedPartition part from PedDisk disk.

If part is an extended partition, it must not contain any logical partitions. part is NOT destroyed. The caller must call ped_partition_destroy(), or use ped_disk_delete_partition() instead.

Returns

0 on error.

ped_disk_set_flag()

int ped_disk_set_flag	(	PedDisk *	disk,
		PedDiskFlag	flag,
		int	state
	)

Set the state (1 or 0) of a flag on a disk.

Note

It is an error to call this on an unavailable flag – use ped_disk_is_flag_available() to determine which flags are available for a given disk label.

Exceptions

PED_EXCEPTION_ERROR

if the requested flag is not available for this label.

ped_disk_set_partition_geom()

int ped_disk_set_partition_geom	(	PedDisk *	disk,
		PedPartition *	part,
		const PedConstraint *	constraint,
		PedSector	start,
		PedSector	end
	)

Sets the geometry of part (i.e.

change a partitions location). This can fail for many reasons, e.g. can't overlap with other partitions. If it does fail, part will remain unchanged. Returns 0 on failure. part's geometry may be set to something different from start and end subject to constraint.

Warning

The constraint warning from ped_disk_add_partition() applies.

Note

this function does not modify the contents of the partition. You need to call ped_file_system_resize() separately.

ped_disk_type_check_feature()

int ped_disk_type_check_feature	(	const PedDiskType *	disk_type,
		PedDiskTypeFeature	feature
	)

This function checks if a particular type of partition table supports a feature.

Returns

1 if disk_type supports feature, 0 otherwise.

ped_disk_type_get()

PedDiskType * ped_disk_type_get

(

const char *

name

)

Return the disk type with a name of "name".

Returns

Disk type; NULL if no match.

ped_disk_type_get_next()

PedDiskType * ped_disk_type_get_next

(

PedDiskType const *

type

)

Return the next disk type registers, after "type".

If "type" is NULL, returns the first disk type.

Returns

Next disk; NULL if "type" is the last registered disk type.

ped_disk_type_register()

void ped_disk_type_register

(

PedDiskType *

type
