func NewReverseReader

func NewReverseReader(reader *os.File) (*ReverseReader, error)

NewReverseReader returns a reader that reads from the end of a file rather than the beginning. It sets the readsize to pagesize and determines the first offset using using modulus.

func (r *ReverseReader) Read() (string, error)

ReverseReader reads from a given offset to the previous offset and then sets the newoff set one pagesize less than the previous read.
