Killing async function calls in node.js

Question

Is it possible to kill an asynchronous function call in node.js or do I have to call the function and then another one to kill the whole process after a specific amount of time?

I know, but I'm talking about functions I didn't write. So I wanna start third party functions, and kill them if they run too long. — K..

Not in any general way, no. You only could if the asynchronous call returned an object that provided a means of canceling the operation it's tied to. — JohnnyHK

Node is single-threaded. How are you going to check whether it has taken too long? — Aaron Dufour

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);
