but how cann i call this function, so that the result is accessible to me :

PointerByReference ptr = new PointerByReference(spot_result.getPointer())

lib.klom_spot_get_result_struct(spot_id, ptr, BLOCKING_TIME);

ptr.getValue() will provide you with the returned pointer. Once you've dereferenced to the address of a structure, you can pass that to Structure.useMemory.

I really try to understand but i still fail.

The call

lib.klom_spot_get_result_struct(spot_id, ptr, BLOCKING_TIME)

should put a list of klom_spot_result_s elements in that ptr.

If i make

ptr.getValue()

that returns a Pointer. but i want something like this (pseudo-code)

klom_spot_result_s[] spot_result = new klom_spot_result_s[20]; lib.klom_spot_get_result_struct(spot_id, ptr, BLOCKING_TIME); for(int i = 0; i<spot_result.length; i++) System.out.println(spot_result[i].startTime);

How can i mangae this behaviour?

klom_spot_result_s s = new klom_spot_result_s(); s.useMemory(ptr.getValue(); klom_spot_result_s[] spot_result = (klom_spot_result_s[])s.toArray(LENGTH);
