struct_group_tagged(9) 💅

okay bestie, you're looking at the struct_group_tagged(9) page from the Kernel API Manual, and it's giving “reusable tag realness” ✨ no cap. Let's get into it.

✨ NAME ✨

struct_group_tagged — create a struct_group with a reusable tag 🎀

🌸 SYNOPSIS 🌸

struct_group_tagged (TAG , NAME , MEMBERS... );

🎀 ARGUMENTS 🎀

• TAG — the tag name for the named sub-struct, periodt 🏷️
• NAME — the identifier name of the mirrored sub-struct, iykyk 💖
• MEMBERS — the member declarations for the mirrored structs 🫶

🦋 DESCRIPTION 🦋

So this one is used to create an anonymous union of two structs with identical layout and size: one anonymous and one named 👑. The former 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 — literally the whole vibe-check of that member group 💅.

It includes a struct tag argument for the named copy, so the specified layout can be reused later 🔥. Reusable layout? Obsessed.
