在node.js中杀死异步函数调用

Question

是否有可能在node.js中终止异步函数调用 ，或者我是否必须调用该函数然后另一个函数在特定时间后终止整个进程 ？

Probably not, But check following code, you can get some idea to achieve the stuff.

var logrunningFunction = function(){
  setTimeout(function(){
    console.log("Delayed");
    cb();
  }, 5000);

};


var cb = function(){
  console.log("long running function completed");
};
logrunningFunction(cb);

setTimeout(function(){
  cb = function(){
    console.log("Overwrite long running handler");
  };
},1000);
