##### multiArgs
Type: `boolean`<br>
Default: `false`
By default, the promisified function will only return the first argument from the callback, which works fine for most APIs. This option can be useful for modules like `kue` that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, instead of just the first argument. This also applies to rejections.
Example:
```js
const kue = require('kue');
const pEvent = require('p-event');
const queue = kue.createQueue();
pEvent(queue, 'job enqueue', {multiArgs: true}).then(result => {
const [id, type] = result;
});
```
