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.

Native Type	Size	Java Type	Common Windows Types
char	8-bit integer	byte	BYTE, TCHAR
short	16-bit integer	short	WORD
wchar_t	16/32-bit character	char	TCHAR
int	32-bit integer	int	DWORD
int	boolean value	boolean	BOOL
long	32/64-bit integer	NativeLong	LONG
long long	64-bit integer	long	__int64
float	32-bit FP	float
double	64-bit FP	double
char*	C string	String	LPTCSTR
void*	pointer	Pointer	LPVOID, HANDLE, LPXXX

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