Functions

func ReadHints

func ReadHints(d *thinio.Conductor, offset int64) (freeCount, nextFree uint32, err error)

ReadHints reads FS Info from the device (at the offset) and returns the freeCount of clusters and the nextFree cluster (if they are known). Otherwise, returns an error.

func WriteFreeCount

func WriteFreeCount(d *thinio.Conductor, offset int64, freeCount uint32) error

WriteFreeCount takes the offset of the FS Info structure and updates the on-disk value of the "free cluster count".

func WriteNextFree

func WriteNextFree(d *thinio.Conductor, offset int64, nextFree uint32) error

WriteNextFree takes the offset of the FS Info structure and updates the on-disk value of the "next free cluster".
