|
|
* - `name-windows.ndll` for Windows targeted ndlls
|
|
* - `name-linux.ndll` for Linux targeted ndlls
|
|
* - `name-mac.ndll` for Mac targeted ndlls

* If:
|
|
* - The platform does not support NDLLs
|
|
* - The NDLL is not found
|
|
* - The Function cannot be found in the NDLL
|
|
* then an empty function will be returned instead, and a message will be shown in logs.
