🦋 die_get_var_innermost_scope(9) 🦋

heyyy bestie, welcome to the Kernel API Manual, section 9 — today’s main character is die_get_var_innermost_scope, and she is literally here to find the innermost scope range of a variable DIE. periodt. 💅

---

✨ NAME ✨

die_get_var_innermost_scope — get the innermost scope range of the given variable DIE. no cap, that’s the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int die_get_var_innermost_scope (Dwarf_Die *sp_die , Dwarf_Die *vr_die ,
       struct strbuf *buf );

---

💖 ARGUMENTS 💖

• sp_die — a subprogram DIE. that’s her 🫶
• vr_die — a variable DIE. the variable in question, fr fr 🌟
• buf — a strbuf for variable byte offset range. put the range here, bestie 💌

---

🔥 DESCRIPTION 🔥

okay so the way this works is: get the innermost scope range of vr_die and store it in buf as "<function_name+[NN-NN,NN-NN]>". literally that exact format, iykyk. 🧚✨
