Overview

Package fifo implements functions to create and open a fifo for inter-process communication in an OS agnostic way. A few assumptions should be made when using this package. First, New() must always be called before Open(). Second Open() returns an io.ReadWriteCloser that is only connected with the io.ReadWriteCloser returned from New().

Functions

func CreateAndRead

func CreateAndRead(path string) (func() (io.ReadCloser, error), error)

CreateAndRead creates a fifo at the given path, and returns an open function for reading. The fifo must not exist already, or that it's already a fifo file

It returns a reader open function that may block until a writer opens so it's advised to run it in a goroutine different from reader goroutine

func IsClosedErr

func IsClosedErr(err error) bool

func OpenWriter

func OpenWriter(path string) (io.WriteCloser, error)

OpenWriter opens a fifo file for writer, assuming it already exists, returns io.WriteCloser

func Remove

func Remove(path string) error

Remove a fifo that already exists at a given path
