find_frame_creation(9)

💖 find_frame_creation(9) 💖

okay bestie, welcome to the Kernel API Manual — we’re doing stack-frame detective work today, and yes, it’s giving very main-character energy 🔍✨

---

🌸 NAME 🌸

find_frame_creation — Search backward to find the instruction that creates the stack frame (hopefully, for the same function the initial PC is in).

---

🎀 SYNOPSIS 🎀

unsigned long * find_frame_creation (unsigned long *pc );

---

🦋 ARGUMENTS 🦋

• pc — Program counter at which to begin the search

---

✨ DESCRIPTION ✨

So here’s the vibe: you start at pc and search backward to find where the stack frame gets created. Iconic little archaeology moment, honestly 🏺💅

• Return: PC at which stack frame creation occurs; NULL if this cannot be found, i.e. a leaf function.

No cap, that NULL case is literally the “welp, leaf function” result 😭🌿
