TRAILING_OVERLAP(9)

okay bestie, welcome to TRAILING_OVERLAP(9) from the Kernel API Manual — this is the kernel API situation where a flexible-array member overlaps with trailing members, and we're gonna read it together 💅✨

🎀 NAME 🎀

TRAILING_OVERLAP — overlap a flexible-array member with trailing members. That's it, that's the whole NAME-section serve.

🌸 SYNOPSIS 🌸

TRAILING_OVERLAP (TYPE , NAME , FAM , MEMBERS );

🦋 ARGUMENTS 🦋

• TYPE — the flexible structure type name, including the struct keyword. Yes, say struct out loud, bestie.
• NAME — the name for a variable to define. Name your variable, name your vibe.
• FAM — the flexible-array member within TYPE. Main character energy, fr fr.
• MEMBERS — trailing overlapping members. The overlap crew that comes after.

💖 DESCRIPTION 💖

It creates a union between a flexible-array member (FAM) in a struct and a set of additional members that would otherwise follow it. So the FAM gets a union situation with the extra members — overlapping instead of just trailing behind. No cap, that's the whole description.
