Hi List. I'm a very beginner on JNA :)

I would like to start test it as soon as possible and I have a really simple question for you.

I have the following C code:

typedef void *MyDriverH; //Handle Type MyDriverH __declspec(dllexport) __stdcall getDriverByIndex(int driverIndex);

What I have to do to get a Driver Handler in Java? I'm trying this solution

public interface MyDLL extends StdCallLibrary{ MyDLL INSTANCE = (MyDLL) Native.loadLibrary("MyDLL", MyDLL.class, new HashMap() {{ put(OPTION_FUNCTION_MAPPER, FUNCTION_MAPPER); }});

public static class MyDriverH extends HANDLE { }

public MyDriverH getDriverByIndex(int driverIndex);

public static class HANDLE extends PointerType { public HANDLE() { }

public HANDLE(Pointer p) { super(p); } }; }

Then using this test code: public class Test { public static void main(String[]args){ MyDLL lib = MyDLL .INSTANCE; MyDriverH driver = lib.getDriverByIndex(1); } }

But I receive this error: Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot locate function 'getDriverByIndex' at com.sun.jna.NativeLibrary.getFunctionAddress(NativeLibrary.java:219) at com.sun.jna.Function.<init>(Function.java:141) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:206) at com.sun.jna.Library$Handler.invoke(Library.java:161) at $Proxy0.getDriverByIndex(Unknown Source) at attempt.Test.main(Test.java:9)

Surelly, I'm doing something wrong but I cant figure out what :)

Can someone help me? Thanks
