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: nameWithNamlen.go
    path of file: ./repos/teller/vendor/github.com/karrick/godirwalk
    
    the code of the file until where you have to start completion: // +build aix darwin dragonfly freebsd netbsd openbsd

package godirwalk

import (
	"reflect"
	"syscall"
	"unsafe"
)

func nameFromDirent(de *syscall.Dirent) []byte {
	// Because this GOOS' syscall.Dirent provides a Namlen field that says how
	// long the name is, this function does not need to search for the NULL
	// byte.
	ml := int(de.Namlen)

	// Convert syscall.Dirent.Name, which is array of int8, to []byte, by
	// overwriting Cap, Len, and Data slice header fields to values from
	// syscall.Dirent fields. Setting the Cap, Len, and Data field values for
