本文整理了Java中com.sun.jna.Native.register()方法的一些代码示例，展示了Native.register()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Native.register()方法的具体详情如下：
包路径：com.sun.jna.Native
类名称：Native
方法名：register

Native.register介绍

[英]When called from a class static initializer, maps all native methods found within that class to native libraries via the JNA raw calling interface.
[中]从类静态初始值设定项调用时，通过JNA原始调用接口将该类中找到的所有本机方法映射到本机库。
