Method description:
Sync version of fsync(). Synchronize the disk cache.
Grammar:
fs.fsyncSync(fd)
Since this method belongs to the fs module, the fs module (var fs= require(" fs ")) needs to be introduced before use.
Receiving parameters:
Fd File descriptor.
Example:
var fs = require('fs');
fs.open('content.txt', 'a', function(err,fd){
if(err){
throw err;
}
console.log('file open');
fs.fsyncSync(fd);
fs.close(fd,function(err){
if(err){
throw err;
}
console.log('file closed');
})
})
Source:
fs.fsyncSync = function(fd) {
return binding.fsync(fd);
};
