📦 version 7.3.1, in nixpkgs unstable

✨ die_find_variable_at — find a given name variable at given address ✨

okay so bestie, we're in the Kernel API Manual (section 9, the fancy kernel-internals one 💅) and this page is about die_find_variable_at. it's giving "detective but for DWARF debug info" 🔍

🌸 SYNOPSIS 🌸

Dwarf_Die * die_find_variable_at (Dwarf_Die *sp_die , const char *name ,
       Dwarf_Addr addr , Dwarf_Die *die_mem );

literally exactly that, no cap 🫶

🎀 ARGUMENTS 🎀

  • sp_die — a function DIE, bestie. that's the starting point, the main character of the search 🔥
  • name — the variable name you're hunting for 💖
  • addr — an address, yes ma'am 📍
  • die_mem — a buffer for the result DIE, so it has somewhere cute to live when it's found 🏠

🦋 DESCRIPTION 🦋

okay so here's the whole vibe: find a variable DIE called name at addr in sp_die. that's it, that's the plot ✨ like, you give it the function DIE, the name, the address, and a spot to stash the answer, and it goes and finds that variable DIE for you. obsessed tbh 💅
