<!-- 需要注意的是:
* PA不涉及特权级的切换, RTFM的时候你不需要关心和特权级切换相关的内容.
* 你需要在自陷指令的实现中调用`isa_raise_intr()`,
而不要把异常响应机制的代码放在自陷指令的helper函数中实现,
因为在后面我们会再次用到`isa_raise_intr()`函数.

## 异常响应机制
需要注意的是, 上文介绍的异常和事件是两个层次的概念:
* 如果你选择的是x86, 通过IDTR中的地址对IDT进行索引的时候, 需要使用`vaddr_read()`. -->

ONScripter用到的API已经在`navy-apps/libs/libSDL_mixer/src/mixer.c`中列出,
我们也无需实现文件中的所有API, 有一些API只是用于链接,
ONScripter在运行部分游戏的时候并不会调用它们.
