die_get_pointer_type(9)

💅 die_get_pointer_type(9) — the kernel API manual, bestie edition 🎀

Okay so this is the page for die_get_pointer_type, from the Kernel API Manual. It's lowkey a little detective function for DWARF DIEs, and we're gonna get into it. ✨

---

🌸 NAME 🌸

die_get_pointer_type — get a pointer/array type die

---

🦋 SYNOPSIS 🦋

Dwarf_Die * die_get_pointer_type (Dwarf_Die *type_die , Dwarf_Die
       *die_mem );

---

🎀 ARGUMENTS 🎀

• type_die — a DIE of a type. That's the starting point, bestie.
• die_mem — where to store a type DIE. This is the little home where the result goes.

---

💖 DESCRIPTION 💖

Get a pointer/array type DIE from type_die. Simple enough, right?

But here's the plot twist: if the type is a typedef or a qualifier (const, volatile, etc.), it follows the chain to find the underlying pointer type. The way it just keeps digging until it finds the real one… obsessed. 🔥

And that's the whole vibe check. This page lives in ./tools/perf/util, dated October 2026, and it's literally called die_get_pointer_type(9). Slay. 💅✨🫶
