PointerByReference is appropriate. Create an instance of your structure in Java and use Structure.useMemory to use the returned pointer. Then use Structure.toArray() to expand from the single structure instance.

Hi, Can somebody give me a code sample of getting a pointer to an array of structs from C as a function parameter?

example of structure:

typedef struct abc { int a; int b; char c; } str;

C function to access which returns the pointer:

void getIt(str **x)

I tried to use PointerByReference on the Java side, but I don't know how to convert the PointerByReference (and if that's the correct class to be used!) object returned into a Java Structure class. I couldn't find any method that would allow me to convert a Pointer or a Pointer[] into an Object and then into the desired Java Structure.

Thanks!
