目前没有可用的官方 Mantle SDK，但有一个 beta 驱动程序（AMD Catalyst™ 14.1 Beta Driver for Windows）。Beta 驱动程序包含一个 mantle64.dll 和一个 mantleaxl64.dll 库。Dependency walker 提供了以下函数定义：

一些假设：要初始化 Mantle，需要调用 grCreateDevice。使用渲染管道时，还需要调用 grCreateGraphicsPipeline。关闭应用程序时，需要通过 grDestroyDevice 销毁设备。图形管线对象需要通过 grDestroyObject 销毁。
