Detailed Description

Access exFat partitions on raw file devices.

Member Function Documentation

bytesPerCluster()

uint32_t ExFatPartition::bytesPerCluster ( ) const

inline

Returns

the number of bytes in a cluster.

bytesPerClusterShift()

uint8_t ExFatPartition::bytesPerClusterShift ( ) const

inline

Returns

the power of two for bytesPerCluster.

bytesPerSector()

uint16_t ExFatPartition::bytesPerSector ( ) const

inline

Returns

the number of bytes in a sector.

bytesPerSectorShift()

uint8_t ExFatPartition::bytesPerSectorShift ( ) const

inline

Returns

the power of two for bytesPerSector.

cacheClear()

uint8_t* ExFatPartition::cacheClear ( )

inline

Clear the cache and returns a pointer to the cache. Not for normal apps.

Returns

A pointer to the cache buffer or zero if an error occurs.

clusterCount()

uint32_t ExFatPartition::clusterCount ( ) const

inline

Returns

the cluster count for the partition.

clusterHeapStartSector()

uint32_t ExFatPartition::clusterHeapStartSector ( ) const

inline

Returns

the cluster heap start sector.

fatLength()

uint32_t ExFatPartition::fatLength ( ) const

inline

Returns

the FAT length in sectors

fatStartSector()

uint32_t ExFatPartition::fatStartSector ( ) const

inline

Returns

the FAT start sector number.

fatType()

uint8_t ExFatPartition::fatType ( ) const

inline

Returns

Type FAT_TYPE_EXFAT for exFAT partition or zero for error.

freeClusterCount()

uint32_t ExFatPartition::freeClusterCount

(

)

Returns

the free cluster count.

init()

bool ExFatPartition::init	(	BlockDevice *	dev,
		uint8_t	part
	)

Initialize a exFAT partition.

Parameters

[in]	dev	The blockDevice for the partition.
[in]	part	The partition to be used. Legal values for part are 1-4 to use the corresponding partition on a device formatted with a MBR, Master Boot Record, or zero if the device is formatted as a super floppy with the FAT boot sector in sector zero.

Returns

true for success or false for failure.

rootDirectoryCluster()

uint32_t ExFatPartition::rootDirectoryCluster ( ) const

inline

Returns

the root directory start cluster number.

rootLength()

uint32_t ExFatPartition::rootLength

(

)

Returns

the root directory length.

sectorsPerCluster()

uint32_t ExFatPartition::sectorsPerCluster ( ) const

inline

Returns

the number of sectors in a cluster.

sectorsPerClusterShift()

uint8_t ExFatPartition::sectorsPerClusterShift ( ) const

inline

Returns

the power of two for sectors per cluster.
