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: futimens.go
    path of file: ./repos/wazero/internal/sysfs
    
    the code of the file until where you have to start completion: //go:build linux || darwin

package sysfs

import (
	"syscall"
	"unsafe"

	"github.com/tetratelabs/wazero/experimental/sys"
)

func timesToPtr(times *[2]syscall.Timespec) unsafe.Pointer { //nolint:unused
	if times != nil {
		return unsafe.Pointer(&times[0])
	}
	return
    
func timesToTimespecs(atim int64, mtim int64) (times *[2]syscall.Timespec) {
	// When both inputs are omitted, there is nothing to change.
	if atim == sys.UTIME_OMIT && mtim == sys.UTIME_OMIT {
		return
	}

	times = &[2]syscall.Timespec{}
	if atim == sys.UTIME_OMIT {
		times[0] = syscall.Timespec{Nsec: _UTIME_OMIT}
		times[1] = syscall.NsecToTimespec(mtim)
	} else if mtim == sys.UTIME_OMIT {
		times[0] = syscall.NsecToTimespec(atim)
		times[1] = syscall.Timespec{Nsec: _UTIME_OMIT}
	} else {
		times[0] = syscall.NsecToTimespec(atim)
		times[1] = syscall.NsecToTimespec(mtim)
	}
	return
