jnajava对应类型_JNA编程之数据类型映射
数据类型 说明 来源 int8_t 带符号8位整数 uint8_t ⽆符号8位整数 int16_t 带符号16位整数 uint16_t ⽆符号16位整数 int32_t 带符号32未整数 uint32_t ⽆符号32位整数
1 ，当前路径是在项⽬下，⽽不是 bin 输出⽬录下。
2 ，数据结构的对应关系：

除了上⾯的类型， JNA 还⽀持常见的数据类型的映射。
char*
NUL-terminated array (native encoding ding )
WString
wchar_t*
NUL-terminated array (unicode)
char**
NULL-terminated array of C strings
WString[]
wchar_t**
NULL-terminated array of wide C strings
Structure
struct*
struct
pointer to struct (argument or return) ( or explicitly )
struct by value (member of struct) ( or explicitly )
Union
union
same as Structure
Structure[]
struct[]
array of structs, contiguous in memory
Callback
(*fp)()
function pointer (Java or native)
NativeMapped
varies
depends on definition
NativeLong
long
platform-dependent (32- or 64-bit integer)
PointerType
pointer
same as Pointer
Unsigned types use the same mappings as signed types. C enums are usually interchangeable with "int".参考链接：
