Does anyone have example OCI code to do an array fetch of objects (not using OTT)

 Hello, I'm writing a query tool in C/OCI and I want it to perform well. So I want to do array fetches. It works perfectly for non-objects. Now I'm trying to add support for object types but I'm struggling with it. The OCI documentation is not very clear on how to cope with arrays.Does anyone have some sample code that I can look at to implement this? I do not know what objects will be queried upfront, so I cannot use the OTT to generate the structures for me. 

Thanks!
