word openmsx::RawTrack::calcCrc	(	int	idx,

	)		const

Convenience method to calculate CRC for part of this track.

void openmsx::RawTrack::clear ( unsigned size )

Clear track data.

Also sets the track length.

vector< RawTrack::Sector > openmsx::RawTrack::decodeAll ( ) const

Get info on all sectors in this track.

Definition at line 102 of file RawTrack.cc.

bool openmsx::RawTrack::decodeNextSector	(	unsigned	startIdx,
		Sector &	sector
	)		const

Get the next sector (starting from a certain index).

bool openmsx::RawTrack::decodeSector	(	byte	sectorNum,
		Sector &	sector
	)		const

Get a sector with a specific number.

Note that if a sector with the same number occurs multiple times, this method will always return the same (the first) sector. So don't use it in the implementation of FDC / DiskDrive code.
