You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: plugin_unix.go
    path of file: ./repos/docker-ce/components/engine/daemon/logger
    
    the code of the file until where you have to start completion: //go:build linux || freebsd
// +build linux freebsd

package logger // import "github.com/docker/docker/daemon/logger"

import (
	"context"
	"io"

	"github.com/containerd/fi
    
func openPluginStream(a *pluginAdapter) (io.WriteCloser, error) {
	// Make sure to also open with read (in addition to write) to avoid borken pipe errors on plugin failure.
	// It is up to the plugin to keep track of pipes that it should re-attach to, however.
	// If the plugin doesn't open for reads, then the container will block once the pipe is full.
	f, err := fifo.OpenFifo(context.Background(), a.fifoPath, unix.O_RDWR|unix.O_CREAT|unix.O_NONBLOCK, 0700)
	if err != nil {
		return nil, errors.Wrapf(err, "error creating i/o pipe for log plugin: %s", a.Name())
	}
	return f, nil
}
