I'm trying to use JNA with a DLL in Windows, so far I was able to successfully call a function called c_aa_find_devices(). But all the functions start with c_aa and I would like to rename it to find_devices(). From what I gather the way to do this is with StdCallFunctionMapper but I can't find the documentation of how to use it in an ex...
I have the following Delphi function: function DoX(const InputBuffer: Pointer; const InputBufferSize: longword; OutputBuffer: Pointer; var OutputBufferSize: longword): longbool; The OutputBuffer and OutputBufferSize would be set in the function as part of the result, with a boolean return to indicate whether the method was successful ...
I have to use some static windows library (*.lib) from java code, I can write C++ JNI wrappers, but I'd rather not do it (not that experienced in C++). What would be the easiest (least developement effort) way use it, performance is not important, since that code will just be fetching some data, that most probrably will be worked on on...
Question: I have a library contains a bunch of static *lib files, I wish to access them from JNA (a Java library that allows one to dynamically call `dll's from JAVA Code), so is there a way to magically change static lib to dll? Code was compiled using Visual studio (hope that is relevant), and I also have appropriate header files. ...

While searching for how to do this, I found some vague discussion about different options, like JNI vs JNA, but not much in the way of concrete examples. Context: if Java's File.renameTo() cannot do it's job (for whatever reason; it is a little problematic), I'd like to fall back to directly using this native Windows function, which is ...
The PInvoke.net site documents PInvoke signatures, user-defined types, and other information that you need to call unmanaged APIs from managed .NET code. Is there a site that does the same for Java's JNA? ...

Until now I have seen only tools and some information for the creation of Delphi code for a given C header file. However, in the 'Delphi first' case, there is a Delphi interface declaration and a generated DLL, and no C header. Are there tools which can extract the necessary information and build a C header file for a DLL? Such a tool ...
