Detailed Description

This class represents a super block and therefore describes the file system on a card. It contains information such as the used block size, the capacity of the card and so on.

Member Function Documentation

int CTSuperBlock::blocks (   )  const [inline]

Returns the number of data blocks on this card. You can use this and the value of blockSize() to determine the for data storage usable capacity of the card.

int CTSuperBlock::blockSize (   )  const [inline]

Returns the size of a data block in bytes. You can use this and the value of blocks() to determine the for data storage usable capacity of the card.

bool CTSuperBlock::changed (   )  const [inline]

string CTSuperBlock::dump (   )

int CTSuperBlock::firstDirBlock (   )  const [inline]

bool CTSuperBlock::isCrypted (   )  const [inline]

Tells whether the data on the card is encrypted.

bool CTSuperBlock::isReadOnly (   )  const [inline]

Tells whether the data on the card should be protected against writing. Todo: I must implement this feature.

const string CTSuperBlock::mediumName (   )  const [inline]

Returns the name you assigned to the card. To protect yourself against acidental data losses you should keeps the names of your card unique !

int CTSuperBlock::mediumSize (   )  [inline]

Returns the capacity of the card. This value does not represent the capacity for data storage, since the file system occupies a part of the memory for management purposes.

int CTSuperBlock::reservedBlocks (   )  const [inline]

void CTSuperBlock::setBlocks (  int  n  )  [inline]

void CTSuperBlock::setBlockSize (  int  n  )  [inline]

void CTSuperBlock::setChanged (  bool  b  )  [inline]

void CTSuperBlock::setFirstDirBlock (  int  i  )  [inline]

void CTSuperBlock::setIsCrypted (  bool  b  )  [inline]

void CTSuperBlock::setIsReadOnly (  bool  b  )  [inline]

void CTSuperBlock::setMediumName (  const string &  n  )  [inline]

void CTSuperBlock::setMediumSize (  int  n  )  [inline]

void CTSuperBlock::setReservedBlocks (  int  i  )  [inline]

void CTSuperBlock::setUserName (  const string &  n  )  [inline]

void CTSuperBlock::setVersion (  int  mj, int  mn )  [inline]

string CTSuperBlock::toString (   )

const string CTSuperBlock::userName (   )  const [inline]

unsigned char CTSuperBlock::versionMajor (   )  const [inline]

Returns the major version of the file system on the card. The file system library will refuse to mount a medium whose major version does not math that of the library.

unsigned char CTSuperBlock::versionMinor (   )  const [inline]

Returns the minor version of the file system on the card. It may differ from that of the library. Todo: When the minor version of the ard is higher than that of the library we should mount the medium readonly !
