die_get_typename(9)

📦 version 7.3.1, in nixpkgs unstable

💅 die_get_typename(9) — like, the Kernel API Manual one 🎀

okay so bestie, welcome to the glow-up of die_get_typename, a little function living its best life in the kernel's DWARF toolbox. it takes a variable DIE and tells you what its type is called. that's the whole vibe. let's get into it ✨

🌸 SYNOPSIS 🌸

int die_get_typename (Dwarf_Die *vr_die , struct strbuf *buf );

literally the whole signature, no notes 💅

🫶 ARGUMENTS 🫶

  • vr_die — the variable DIE we're interrogating. it's the main character here 👑
  • buf — a strbuf where the result type name gets dropped off. think of it as the group chat where the answer lands 💌

✨ DESCRIPTION ✨

so what it does: it grabs the name of vr_die and stores it into buf. iconic behaviour, no cap 🔥

Return values, listen up 📣

  • returns 0 if it succeeded — slay, we love a clean win 💖
  • returns -ENOENT if it failed to find the type name — not a slay, a little sad, but that's the contract 🥲

and here's the part everyone forgets, so pay attention bestie 👀 — the result will store the typedef name if possible, and it'll store "*(function_type)" if the type is a function pointer. that's it, that's the deal, no cap 🧚

👑 SEE ALSO 👑

all the sibling functions, in the order the manpage gave them, because we do not skip and we do not merge 💯

also the source file, straight from the manpage: Kernel file ./tools/perf/util/dwarf-aux.c 📁 — that's where this whole friend group lives, iykyk

okay that's the page!! and for the sign-off: this one's served up from ./tools/perf/util, dated October 2026, and it's filed under die_get_typename(9) 🦋 tysm for reading bestie, go read your DWARF, periodt 💜🌈
