JNA编程之二：数据类型映射

以下关于C/C++及Java数据类型间的映射关系摘自JNA官网，由于笔者英语水平有限就不做翻译了，但是只要你曾经是个C/C++程序员，估计能领悟到它的具体意思。

Default Type Mappings

Java primitive types (and their object equivalents) map directly to the native C type of the same size.

Unsigned types use the same mappings as signed types. C enums are usually interchangeable with "int".
