💖 die_find_variable_by_addr(9) — Kernel API Manual 💖

okay bestie, welcome to the die_find_variable_by_addr(9) page! This is the lookup where we find a variable DIE by its address, and every single argument plus every SEE ALSO reference is staying right here. Let’s get into it 🫶

🌸 NAME 🌸

die_find_variable_by_addr - Find variable located at given address

✨ SYNOPSIS ✨

Dwarf_Die * die_find_variable_by_addr (Dwarf_Die *sc_die , Dwarf_Addr
       addr , Dwarf_Die *die_mem , Dwarf_Die *type_die , int *offset );

🎀 ARGUMENTS 🎀

• sc_die — a scope DIE
• addr — the data address to find
• die_mem — a buffer to save the resulting DIE
• type_die — -- undescribed -- (the page literally says that, no extra lore 😭)
• offset — the offset in the resulting type

💅 DESCRIPTION 💅

Find the variable DIE located at the given address (in PC-relative mode). This is usually for global variables. That’s the whole quest, bestie 💅
