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: container.go
    path of file: ./repos/moby/vendor/github.com/Microsoft/hcsshim/internal/runhcs
    
    the code of the file until where you have to start completion: //go:build windows

package runhcs

import (
	"bytes"
	"errors"
	"fmt"
	"io"
	"os"
	"syscall"
	"time"

	"github.com/Microsoft/go-winio/pkg/guid"
)

// ContainerState represents
    
func GetErrorFromPipe(pipe io.Reader, p *os.Process) error {
	serr, err := io.ReadAll(pipe)
	if err != nil {
		return err
	}

	if bytes.Equal(serr, ShimSuccess) {
		return nil
	}

	extra := ""
	if p != nil {
		_ = p.Kill()
		state, err := p.Wait()
		if err != nil {
			panic(err)
		}
		extra = fmt.Sprintf(", exit code %d", state.Sys().(syscall.WaitStatus).ExitCode)
	}
	if len(serr) == 0 {
		return fmt.Errorf("unknown shim failure%s", extra)
	}

	return errors.New(string(serr))
}
