Interface Struct<T extends Struct<T>>

Type Parameters:
T - the type of the actual structure interface
public interface Struct<T extends Struct<T>>
The representation of a C structure.

Returning a Struct from a downcall method or pass a Struct by value requires a registration to tell UnmarshalProcessor how to create an instance of the Struct and DescriptorTransformer the layout of the structure.
