| * struct { |
| * uint64_t version; |
| * union { |
| * struct version v1; |
| * ... |
| * } u; |
| * |
| * Each top level structure maintains independent versioning and is defined |

| * #define STRUCTNAME_V1 0x1 |
| * ... |
| * #define STRUCTNAME_Vn 0x### |
| * #define STRUCTNAME_VERSION STRUCTNAME_Vn |
| * |
| * Version fields should ALWAYS be declared as type uint64_t. This is because |
| * 64-bit compilers tend to pad the structure to 64-bit align the start of |
| * union structure members. Having an explicit 64-bit version helps to maintain |
| * consistent structure layout between 32-bit and 64-bit compilers. |
| * |
| * Updates to the structures UAPI should always define a new sub-structure to |
| * place within the union, and update STRUCTNAME_VERSION to reference the |
| * new version number. |
| * |
| * User mode code should always set the 'version' field to STRUCTNAME_VERSION. |
