💖 ELF_GETAROFF(3) 💖

okay bestie, welcome to the Libelf Programmer's Manual ✨ this is elf_getaroff from section 3 of the manual, and she's a tiny little function with main character energy 🎀

🌸 NAME 🌸

elf_getaroff — retrieve the offset of an archive member header 🗂️

✨ SYNOPSIS ✨

#include <libelf.h>

int64_t elf_getaroff(Elf *elf);

literally that's it, one function, one argument, we love a low-effort icon 💅

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function returns the file offset, in bytes, of the archive member header that the ELF descriptor is currently pointing at. 📍

it's the offset of the member header in the parent archive file, no cap. so like, the archive is the parent, the member header lives inside it, and this tells you exactly where. 🔍

and the way this offset is actually useful?? you can hand it straight to elf_rand 🎯 iykyk

🫶 PARAMETERS 🫶

  • elf — an Elf descriptor referring to a member of an archive file header. that's your girl. she's the whole input. 🌷

💀 RETURN VALUE 💀

  • returns the file offset, in bytes, of the archive member header that elf refers to ⭐
  • if elf is NULL, or if it's not a member of an archive, it returns -1. so like, if you get a -1 bestie... that's the sad path 😭

heads up bestie: this elfutils libelf function may not be found in other libelf implementations. so if you're on a different libelf and she's not there... that's why, don't panic 💅
