\brief Defines a new resource type within this instance.

This can be used to define a new resource type that the guest will be able to import. Here the resource is a type, often a host-defined type, which can be used to distinguish and definite different types of resources. A destruction callback is also specified via destructor which has private data data along with an optional finalizer for the data too.

\return on success NULL, otherwise an error
