func OpenFifo ¶

func OpenFifo(ctx context.Context, fn string, flag int, perm os.FileMode) (io.ReadWriteCloser, error)

OpenFifo opens a fifo. Returns io.ReadWriteCloser. Context can be used to cancel this function until open(2) has not returned. Accepted flags:

• syscall.O_CREAT - create new fifo if one doesn't exist
• syscall.O_RDONLY - open fifo only from reader side
• syscall.O_WRONLY - open fifo only from writer side
• syscall.O_RDWR - open fifo from both sides, never block on syscall level
• syscall.O_NONBLOCK - return io.ReadWriteCloser even if other side of the fifo isn't open. read/write will be connected after the actual fifo is open or after fifo is closed.
