Hi Claudio, Sorry for my late response. I have gone through Claudio's solution. It's good. But I think this is not a common solution. There are two points: 1. This solution must use Pointerbyreference to encapsulate the Pointer. This is not clean.
Yes, as I said, this adds another level of indirection --- which is pretty useless in Java.
2. Libvirt provides virFree method. But a common library could not provide memory management functions.
Sorry, I don't get your point here.
My proposal is as following: 1. Add a new Class Libc.java public interface Libc extends Library{ Libc INSTANCE = (Libc) Native.loadLibrary("c", Libc.class);
public void free(Pointer p); }
Not every platform has a shared library called "c". On Windows this would be msvcrt.dll for the Microsoft runtime. So, you would need to branch on the platform to load whatever library seems appropriate. Also, I just discovered that since version 3.3.0 JNA provides a public free method itself. Since I get crashes when using callback functions with JNA 3.2.7 in certain circumstances it is better just to require a newer version of JNA, IMHO. I'll post a few patches with improvements and memory fixes tomorrow. -- AV-Test GmbH, Henricistraße 20, 04155 Leipzig, Germany Phone: +49 341 265 310 19 Web:<http://www.av-test.org> Eingetragen am / Registered at: Amtsgericht Stendal (HRB 114076) Geschaeftsfuehrer (CEO): Andreas Marx, Guido Habicht, Maik Morgenstern
