这个是用来调用标准DLL的类
Class for working with a reference to a single Win32 function exposed in standard DLL's. The Jawin Userguide - Calling a DLL Entry Point
这个文档可以当作如何使用JAWIN的参考
document should be consulted about how to use this class. 包括了一些常用的函数的调用方法
Contains several invoke_*-methods for some standard function signatures.
可以大概分成一下三种
These falls in three groups: invoke_I- 一些以INT做为标准返回的本地方法的调用函数
methods for native methods with a standard int as [retval]
invoke_OI-一些最后参数作为[out]返回的本地方法的调用函数methods for native methods with a last parameter being a [out] int
invoke_S-一些返回数组的本地方法的调用函数（也可以被使用那些返回为STRUCTS的方法）
methods for native methods returning a byte array (can be used for methods returning structs)
Please notice that because of the TYPEDEF in C/C++ many method signatures are covered by the relatively few invoke_*-methods, as eg. HWND, HRESULT, LONG etc. all can be represented as Java int's.
请注意C/C++的返回信息的类型和JAVA不同，但是有一些类型可以用java的一些类型代替
比图 HWND,HRRSULT LONG等等 这些都能被表示成为java的int
If working with a function that does not match one of the standard signatures, use the generic invoke(String, int, NakedByteStream, Object[], ReturnFlags).
如果使用的一些函数不能和标准的调用方法不匹配，请使用标准的调用方法Version:
