For doing a memset range, the preferred method is to use a struct_group in the structure itself. This makes the range self-documenting, and allows the compile to validate the exact size, makes it addressable, etc. The other memset helpers are for "everything to the end", which doesn't usually benefit from the struct_group style of range declaration.
