Types

type Tailer

type Tailer struct {
	io.ReadCloser
}

A Tailer holds an io.ReadCloser interface. It implements a Read() function which emulates the tailf UNIX program.

func New

func New(path string) (*Tailer, error)

New returns a new Tailer for the given path.

func (*Tailer) Read

func (t *Tailer) Read(b []byte) (int, error)

Read provides a tailf like generator by handling the io.EOF error. It returns the number of bytes read and any error encountered. At end of file, when no more input is available, Read handles the io.EOF error by continuing the reading loop.
