ELF32_GETEHDR(3)

💖 ELF32_GETEHDR(3) 💖

okay so bestie, we're in the Libelf Programmer's Manual and this is the page for elf32_getehdr. yes it's a mouthful. yes it slays. let's go 🦋

✨ NAME ✨

elf32_getehdr — grab the ELF header for a 32-bit ELF descriptor, no cap 🎀

🌸 SYNOPSIS 🌸

#include <libelf.h>

Elf32_Ehdr *elf32_getehdr(Elf *elf);

💅 DESCRIPTION 💅

so elf32_getehdr retrieves the ELF header for the 32-bit ELF descriptor you hand it, elf. like, it goes and gets it for you. queen behavior.

and the ELF header is not a vibe-light thing — it's holding crucial metadata about the ELF file. we're talking:

• the type
• the machine
• the version
• the entry point
• the program header table offset
• the section header table offset

if you wanna know more about the ELF header itself, go read elf(5). it's giving lore. 📖✨

🫶 PARAMETERS 🫶

• elf — a pointer to the ELF descriptor you want the ELF header from. that's the one. that's your girl.

👑 RETURN VALUE 👑

on success? elf32_getehdr hands you a pointer to the Elf32_Ehdr structure. periodt. 💖

but if the ELF descriptor is invalid, or it's not a 32-bit ELF? it returns NULL, and sets an error code you can retrieve with elf_errno(3). so like… go check that. don't just sit there staring at your NULL, bestie 😭
