dwarf_frame_reg(9)

💅 dwarf_frame_reg(9) — from the Kernel API Manual ✨

🌸 NAME 🌸

dwarf_frame_reg — return a DWARF register 🎀

✨ SYNOPSIS ✨

struct dwarf_reg * dwarf_frame_reg (struct dwarf_frame *frame , unsigned
int reg_num );

🫶 ARGUMENTS 🫶

• frame — the DWARF frame to search in for reg_num 🔍
• reg_num — the register number to search for 🔢

💖 DESCRIPTION 💖

Okay so bestie, this one looks up and returns the dwarf reg reg_num for this frame. That's the whole main character move ✨.

If reg_num is an invalid register number, it returns NULL — no cap, that's your signal that the lookup didn't land 💀.
