/**
|
||
|
|
* This example creates an ffi.Callback from the "Math.abs()" JavaScript function
|
||
|
|
* then creates a ffi.ForeignFunction from that callback function pointer.
|
||
|
|
*
|
||
|
|
* The result is basically the same as calling "Math.abs()" directly, haha!
|
||
|
|
*
|
||
|
|
* This example should basically just run forever, in an endless loop.
|
||
|
|
* This file is a "pummel test" of sorts for:
|
||
|
|
* https://github.com/rbranson/node-ffi/issues/74
|
||
|
|
*
|
||
|
|
* We should run this file periodically for a period of ~10 minutes to make sure
|
||
|
|
* it doesn't crash ever.
