Question

I tried searching the Node.js source code, but I could not find it. By default, where would I find the Node.js code that handles SIGINT (Ctrl+C) by default in the following example:

var http = require('http');

var server = http.createServer(function(req, res) {
  res.writeHead(200);
  res.end('Hello Http');
});


server.listen(5001);

Node’s default SIGINT handler is in node.cc, but it doesn’t do much. It calls signalExit, which does

uv_tty_reset_mode();
_exit(1);

You can add your own handler in node.js with

process.on('SIGINT', function () {
    // handle
});
