ELF_NDXSCN(3)

💖 ELF_NDXSCN(3) 💖

okay bestie, welcome to the Libelf Programmer's Manual — this one's short and sweet, a lil snack of a man page, and honestly? it ate. we're talking elf_ndxscn, the function that tells you which number a section descriptor is in the lineup. let's go 🦋

---

✨ NAME ✨

elf_ndxscn — retrieve the index of a descriptor for an ELF file section

like, it gets you the index. of the descriptor. for a section. in an ELF file. no cap, that's the whole job 💅

---

✨ SYNOPSIS ✨

#include <libelf.h>

size_t elf_ndxscn(Elf_Scn *scn);

---

✨ DESCRIPTION ✨

so the elf_ndxscn function retrieves the index of the section descriptor that scn points at. that's it. that's the vibe. you hand it a pointer, it hands you back a number. iconic behavior, honestly 🎀

---

✨ PARAMETERS ✨

• scn — an Elf_Scn pointer to the section descriptor whose index you're trying to get at. it's the little guy you're asking about 🥺

---

✨ RETURN VALUE ✨

elf_ndxscn returns the index of the section descriptor. BUT — and this is the plot twist — if scn is NULL, it returns SHN_UNDEF. and heads up, SHN_UNDEF is zero. so like, zero. the big nothing. 0. just so we're clear 👑⭐

ngl if you're getting 0 back and you're confused, check if you passed a NULL pointer. the function is literally telling you 💀
