/**
|
|
* __struct_group() - Create a mirrored named and anonyomous struct
|
|
*
|
|
* @TAG: The tag name for the named sub-struct (usually empty)
|
|
* @NAME: The identifier name of the mirrored sub-struct
|
|
* @ATTRS: Any struct attributes (usually empty)
|
|
* @MEMBERS: The member declarations for the mirrored structs
|
|
*
|
|
* Used to create an anonymous union of two structs with identical layout
|
|
* and size: one anonymous and one named. The former's members can be used
|
|
* normally without sub-struct naming, and the latter can be used to
|
|
* reason about the start, end, and size of the group of struct members.
|
|
* The named struct can also be explicitly tagged for layer reuse, as well
|
|
* as both having struct attributes appended.
