✨ ELF_VERSION(3) ✨

okay bestie, so like — this is elf_version from the Libelf Programmer's Manual, and it's literally the first thing you gotta do with libelf. no cap. it's giving "get your library in order before the party starts" 💅

🌸 NAME 🌸

elf_version — set the ELF version for libelf.

🎀 SYNOPSIS 🎀

#include <libelf.h>

unsigned int elf_version(unsigned int version);

💖 DESCRIPTION 💖

So elf_version sets libelf's ELF version to whatever value you hand it. and here's the tea: you MUST call this function before you use any other libelf functions. like, any of them. all of them. periodt. 🙈

think of it as the vibe check that libelf needs before it'll talk to you.

🦋 PARAMETERS 🦋

  • version — an unsigned int value specifying the desired ELF version for the library. you should set this to EV_CURRENT to indicate the current ELF version. and rn? EV_CURRENT is the only supported ELF version. that's it, that's the whole menu, bestie. 🍓

🌈 RETURN VALUE 🌈

okay so here's how the returns go down:

  • if version is supported, the function returns EV_CURRENT and sets the library's ELF version to that value. slay. ✨
  • if the version you passed is EV_NONE, it returns EV_CURRENT and does not set the library's ELF version. cute of it.
  • if the version you passed isn't supported at all? it returns EV_NONE. 💀

😭 REPORTING BUGS 😭

found a bug? not me gatekeeping — report it to <elfutils-devel@sourceware.org> or hit up https://sourceware.org/bugzilla/. go off, king. 👑

fr fr bestie: call elf_version with EV_CURRENT first, or nothing else works. iykyk.
