Since this method belongs to the fs module, the fs module (var fs= require(" fs "))

needs to be introduced before use

Receive parameter:

fd                             file descriptor

Example of :

var fs = require('fs');

fs.open('content.txt', 'a', function(err,fd){

 if(err){

  throw err;

 }

 console.log('file open');

 

 var statInfo = fs.fstatSync(fd);

 console.log(statInfo);

 

 fs.close(fd , function(){

  console.log('file close');

 })

})

source code:

fs.fstatSync = function(fd) {

  return binding.fstat(fd);

};
