method description:

Change the timestamp of the file referenced by the file descriptor provided by 1 file.

Change timestamp for short


fs.futimes(fd, atime, mtime, callback)

Since this method belongs to fs module, fs module (var fs= require(" fs ") needs to be introduced before use.)

receive parameters:

fd                       identifier



callback     callback

Example:'/path/demo1.txt', 'a', function (err, fd) {
  if (err) {
    throw err;
  fs.futimes(fd, 1388648322, 1388648322, function (err) {
    if (err) {
      throw err;
    console.log('futimes complete');
    fs.close(fd, function () {

source code:

fs.futimes = function(fd, atime, mtime, callback) {
  atime = toUnixTimestamp(atime);
  mtime = toUnixTimestamp(mtime);
  binding.futimes(fd, atime, mtime, makeCallback(callback));
