die_find_top_inlinefunc(9)

✨ NAME ✨

die_find_top_inlinefunc — search the top inlined function at given address. 💫

okay so this is the Kernel API Manual page for die_find_top_inlinefunc(9), and it’s literally here to help you find the top inlined function at a given address, bestie. no cap. 🫶

---

✨ SYNOPSIS ✨

the signature, verbatim, because we do not play with code:

Dwarf_Die * die_find_top_inlinefunc (Dwarf_Die *sp_die , Dwarf_Addr addr
, Dwarf_Die *die_mem );

---

🎀 ARGUMENTS 🎀

• sp_die — a subprogram DIE which includes addr. that’s the starting point, bestie 🧚
• addr — the target address. the one we’re hunting for 🔥
• die_mem — a buffer for the result DIE. it’s where the found DIE gets stored 💖

---

💅 DESCRIPTION 💅

Search for an inlined function DIE which includes addr. if it finds one, it stores the DIE to die_mem and returns it. if it fails, it returns NULL. periodt. 😭

and here’s the key part, so listen up: even if several inlined functions are expanded recursively, this does not trace it down — it just returns the topmost one. it’s giving “top of the stack only, we’re not doing the whole recursive scavenger hunt.” 💀✨

bestie PSA: NULL means it failed — not a vibe, just no match. 🙈
