void TskVsInfo::close ( )

inline

Closes an open volume system.

See for tsk_vs_close() details.

References tsk_vs_close().

unsigned int TskVsInfo::getBlockSize ( ) const

inline

Return size of volume system blocks in bytes.

Returns: size of a block in bytes

References TSK_VS_INFO::block_size.

const TskImgInfo* TskVsInfo::getImgInfo ( ) const

inline

Get a reference to the parent image object.

Returns: Pointer to object or NULL on error. Caller is responsible for freeing object.

References TSK_VS_INFO::img_info.

TSK_DADDR_T TskVsInfo::getOffset ( ) const

inline

Return the byte offset where volume system starts in disk image.

Returns: byte offset

References TSK_VS_INFO::offset.

const TskVsPartInfo* TskVsInfo::getPart ( TSK_PNUM_T a_idx ) const

inline

Get reference to a volume in the volume system.

See tsk_vs_part_get() for details.

Parameters

a_idx Index for volume to return (0-based)

Returns: Pointer to partition or NULL on error. Caller is responsible for freeing object.

References tsk_vs_part_get().

TSK_PNUM_T TskVsInfo::getPartCount ( ) const

inline

Return number of partitions.

Returns: number of partitions

References TSK_VS_INFO::part_count.

TSK_VS_TYPE_ENUM TskVsInfo::getVsType ( ) const

inline

Return type of volume system / media management.

Returns: type of volume system / media management

References TSK_VS_INFO::vstype.

uint8_t TskVsInfo::open	(	TskImgInfo *	a_imgInfo,
		TSK_DADDR_T	a_offset,
		TSK_VS_TYPE_ENUM	a_type
	)

inline

Open a disk image and process the media management system data.

See tsk_vs_open() for details.

Parameters

a_imgInfo	The opened disk image.
a_offset	Byte offset in the disk image to start analyzing from.
a_type	Type of volume system (including auto detect)

Returns: 1 on error and 0 on success.

References tsk_vs_open().

ssize_t TskVsInfo::readBlock	(	TSK_DADDR_T	a_addr,
		char *	a_buf,
		size_t	a_len
	)

inline

Reads one or more blocks of data with an address relative to the start of the volume system.

See tsk_vs_read_block() for details.

Parameters

a_addr	Sector address to read from, relative to start of VOLUME SYSTEM.
a_buf	Buffer to store data in
a_len	Amount of data to read (in bytes - must be a multiple of block_size)

Returns: Number of bytes read or -1 on error

References tsk_vs_read_block().

static void TskVsInfo::typePrint ( FILE * a_hFile )

inlinestatic

See tsk_vs_type_print() for details.

Parameters

a_hFile Handle to print to.

References tsk_vs_type_print().

static TSK_VS_TYPE_ENUM TskVsInfo::typeSupported ( )

inlinestatic

Return the supported volume system types.

See tsk_vs_type_supported() for details.

Returns: The bit in the return value is 1 if the type is supported.

References tsk_vs_type_supported().

static const char* TskVsInfo::typeToDesc ( TSK_VS_TYPE_ENUM a_type )

inlinestatic

Return the string description of a partition type ID.

See tsk_vs_type_todesc() for details.

Parameters

a_type Volume system type

Returns: description of type or NULL on error

References tsk_vs_type_todesc().

static TSK_VS_TYPE_ENUM TskVsInfo::typeToId ( const TSK_TCHAR * a_str )

inlinestatic

Parse a string with the volume system type and return its internal ID.

See tsk_vs_type_toid() for details.

Parameters

a_str String to parse.

Returns: ID of string (or unsupported if the name is unknown)

References tsk_vs_type_toid().

static const char* TskVsInfo::typeToName ( TSK_VS_TYPE_ENUM a_type )

inlinestatic

Return the string name of a partition type ID.

See tsk_vs_type_toname() for details.

Parameters

a_type Volume system type

Returns: name of type or NULL on error

References tsk_vs_type_toname().

uint8_t TskVsInfo::vsPartWalk	(	TSK_PNUM_T	a_start,
		TSK_PNUM_T	a_last,
		TSK_VS_PART_FLAG_ENUM	a_flags,
		TSK_VS_PART_WALK_CPP_CB	a_action,
		void *	a_ptr
	)

inline

Walk a range of partitions and pass the data to a callback function.

See tsk_vs_part_walk() for details.

Parameters

a_start	Address of first partition to walk from.
a_last	Address of last partition to walk to.
a_flags	Flags that are used to identify which of the partitions in the range should be returned (if 0, all partitions will be returned).
a_action	Callback action to call for each partition.
