struct_group(9)

✨ NAME ✨

struct_group — wrap a set of declarations in a mirrored struct. This is the struct_group(9) manual page, bestie 💅

🎀 SYNOPSIS 🎀

struct_group (NAME , MEMBERS... );

💖 ARGUMENTS 💖

• NAME — the identifier name of the mirrored sub-struct. Like, the name-name for the named twin 🫶
• MEMBERS — the member declarations for the mirrored structs. All the little struct members go here ✨

🦋 DESCRIPTION 🦋

Okay so the whole vibe: this 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. No cap, that's the entire tea 😌
