💖 GELF_GETPHDR(3) 💖

okay bestie, welcome to the Libelf Programmer's Manual ✨ this one is literally called gelf_getphdr and it's here to hand you program header table entries that don't care about class 🫶

🌸 NAME 🌸

gelf_getphdr — Retrieve class-independent program header table entries for an ELF object file

---

✨ SYNOPSIS ✨

#include <gelf.h>

GElf_Phdr *gelf_getphdr (Elf *elf, int ndx, GElf_Phdr *dst);

---

🦋 DESCRIPTION 🦋

so basically 💅 you're retrieving the class-independent program header table entry sitting at index ndx inside the ELF descriptor elf, and you're stashing it in dst. that's the whole vibe. slay.

and if you're like "okay but how many entries even are there tho" — go check elf_getphdrnum(3), it tells you exactly how to acquire the number of entries in the program header table. no cap. 👑

---

🎀 PARAMETERS 🎀

• elf — the ELF descriptor of kind ELF_K_ELF that you're pulling the program header table entry out of 🧚
• ndx — the index of the program header table entry you want, like a lil number ticket 🎟️
• dst — pointer to a GElf_Phdr that you provide, bestie, and it receives the requested program header table entry 💖

---

⭐ RETURN VALUE ⭐

on success? the requested entry gets copied into dst and then dst is returned. iconic. ✅

on failure? NULL comes back and elf_errno gets set. 😭

and if elf is NULL? then NULL is returned and elf_errno is not set. like, we're not even gonna touch it. 🙈
