Hi,

I have structure A,B and C.

public class A extends Structure { public A() { super(-1, ALIGN_NONE); }

public byte[] aField1 = new byte[3]; public NativeLong aField2; public short aField3; public Pointer aField4; public NativeLong aField5;

public void useMemory(Pointer p) { super.useMemory(p); } }

public class B extends Structure { public B() { super(-1, ALIGN_NONE); } public short bFild1; public NativeLong bField2; public short bField3; public Pointer bField4 public NativeLong bField5; }

public class C extends Structure { public C() { super(-1, ALIGN_NONE); } public NativeLong[] cFild1= new NativeLong[5]; }

I invoke my C function passing structure A, where i set A.aFild4 = B.getPointer() and B.bFild3 = C.getPointer(), see the example:

A a = new A(); a.aFild1 = 0; a.aFild2 = 1;

B b = new B(); b.bField1 = "ABC".getBytes(); b.bField2= new NativeLong(20); b.bField3 = 1;

C c = new C(); NativeLong[] values = new NativeLong[5]; values[0] = new NativeLong(1); values[1] = new NativeLong(0); values[2] = new NativeLong(0); values[3] = new NativeLong(0); values[4] = new NativeLong(0); c.cField1 = values; b.bField4 = numerario.getPointer();

b.bField5 = new NativeLong(0); a.aField4 = b.getPointer();

B oP = new B(); oP.useMemory(a.aField4); //I just set with b.getPointer() oP.read(); System.out.println(oP);//Here print B Structure with all attributes NULL or Zero

Here print B Structure with all attributes NULL or Zero (the same with new B()) and when I invoke my C Function response is a error, that is my problem... somebody help me?
