JNA Memory Leak - How to fix?

Question

        public static User32 USER32_INSTANCE = (User32) Native.loadLibrary(\"user32\", User32.class);

        user32 = USER32_INSTANCE;

        user32.EnumWindows((hWn         


        

Answer 1

After opening a handle to a process with OpenProcess, you need to close the process handle with CloseHandle. Remember that OpenProcess returns a Handle, not a Pointer.

Kernel32.INSTANCE.CloseHandle(process);

Note also that JNA provides a pretty in-depth mapping of the Windows API out of the box in the net.java.dev.jna-platform package (I think?)
