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: mount.go
    path of file: ./repos/buildkit/vendor/github.com/Microsoft/hcsshim/computestorage
    
    the code of the file until where you have to start completion: //go:build windows

package computestorage

import (
	"context"

	"github.com/Microsoft/hcsshim/internal/interop"
	"github.com/Microsoft/hcsshim/internal/oc"
	"github.com/pkg/errors"
	"golang.org/x/sys/windows"
)

// GetLayerVhdMountPath returns the volume path for a virtual disk of a writable container layer.
func GetLayerVhdMountPath(ctx context.Context, vhdHandle window
    
func GetLayerVhdMountPath(ctx context.Context, vhdHandle windows.Handle) (path string, err error) {
	title := "hcsshim::GetLayerVhdMountPath"
	ctx, span := oc.StartSpan(ctx, title) //nolint:ineffassign,staticcheck
	defer span.End()
	defer func() { oc.SetSpanStatus(span, err) }()

	var mountPath *uint16
	err = hcsGetLayerVhdMountPath(vhdHandle, &mountPath)
	if err != nil {
		return "", errors.Wrap(err, "failed to get vhd mount path")
	}
	path = interop.ConvertAndFreeCoTaskMemString(mountPath)
	return path, nil
}
