How to use the bindings.DeviceINQ function in bindings

(function () {
    "use strict";

    // javascript shim that lets our object inherit from EventEmitter
    var DeviceINQ = require('bindings')('BluetoothSerialPort.node').DeviceINQ,
        events = require('events');

    // extend prototype
    function inherits(target, source) {
        var k;

        for (k in source.prototype) {
            target.prototype[k] = source.prototype[k];
        }
    }

    inherits(DeviceINQ, events.EventEmitter);
    exports.DeviceINQ = DeviceINQ;

}());
