I wanted to write a function inside the syslogd function and that function needs to return some value, can anyone please help me regarding this?

This simple piece of code can give all the json array information from server but i want to write a function inside this and i want to return those values .

 /**
 * Created by sysadmin on 4/6/2017.
 */
var Syslogd = require('syslogd');
var fs = require('fs');
var str1='';
var str2='';
var str3='';
var str4='';
var row=0;
Syslogd(function(info) {

    /*
     info = {
     facility: 7
     , severity: 22
     , tag: 'tag'
     , time: Mon Dec 15 2014 10:58:44 GMT-0800 (PST)
     , hostname: 'hostname'
     , address: '127.0.0.1'
     , family: 'IPv4'
     , port: null
     , size: 39
     , msg: 'info'
     }
     */
     console.log(info);

}).listen(514, function(err) {
    console.log('start'+err);
});

I want to write a function inside syslogd function and return some values.
