method description:

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

Change timestamp for short

syntax:

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

atime

mtime

callback     callback

Example:

fs.open('/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 () {

      console.log('Done');

    });

  });

});

source code:

fs.futimes = function(fd, atime, mtime, callback) {

  atime = toUnixTimestamp(atime);

  mtime = toUnixTimestamp(mtime);

  binding.futimes(fd, atime, mtime, makeCallback(callback));

};
