die_collect_global_vars(9) 💖

okay so this page is from the Kernel API Manual, and it’s giving “collect every global variable and save the receipts” energy. bestie, let’s get into it ✨

---

🌸 NAME 🌸

die_collect_global_vars — save all global variables. that’s the whole assignment, no cap 💅

---

✨ SYNOPSIS ✨

void die_collect_global_vars (Dwarf_Die *cu_die , struct die_var_type
**var_types );

---

💅 ARGUMENTS 💅

• cu_die — a CU DIE 🫶
• var_types — a pointer to save the resulting list. slay, that’s where the loot goes 💖

---

🦋 DESCRIPTION 🦋

Save all global variables in the cu_die and save them to var_types. The var_types is a singly-linked list containing type and location info. Actual type can be retrieved using dwarf_offdie with die_off later. iykyk 🔥

Callers should free var_types. yes bestie, that’s your job — don’t leave it hanging, periodt 💀
