I just reviewed your code. My suggestion is to implement a class
in JavaScript to wrap your C++ addon, then you can easily implement event
dispatcher in JavaScript with callback mechanism.
For low-level things that's like byte processing, it's better to do its all
jobs in C++.
How about this design:
var Wayland = require('wayland');
var wl = new Waylan();
// wl.init will do connect(), get_registry(), and initialize event emitter
wl.init(function() {
});
---
Wayland.Client Class:
connect()
Wayland.Display Class:
get_registry()
roundtrip()
Wayland.Registry Class:
on() // event listener
emit() // emitter
Cheers,
Fred
