πŸ’– ELF_NEXTSCN πŸ’–

okay bestie, gather round, because this is the elf_nextscn page from the Libelf Programmer's Manual (yes, manual section 3, we love a library function moment) and it's literally just "gimme the next section bestie" and honestly? iconic.


✨ NAME ✨

elf_nextscn β€” return the next section in an ELF descriptor. that's it. that's the whole job. slay.


🌸 SYNOPSIS 🌸

#include <libelf.h>

Elf_Scn *elf_nextscn(Elf *elf, Elf_Scn *scn);

look at her. one function, two args, zero drama.


πŸ¦‹ DESCRIPTION πŸ¦‹

so the elf_nextscn() function hands you back a handle to the next section in the ELF object descriptor elf. walking the section list, one step at a time, main character energy fr fr.

if scn is NULL, you get the first section, which has index 1. and listen β€” section index 0 is reserved and skipped. do not come for index 0, she is not available, she is booked and busy being reserved. periodt.

if scn is not NULL, you get the section immediately following it. and if there are no further sections? you get NULL. that's the end of the list, bestie, we've reached the last slide of the carousel.


πŸŽ€ PARAMETERS πŸŽ€

  • elf β€” a pointer to an ELF descriptor. your whole elf object, your vibe, your context.
  • scn β€” a section handle returned by elf_getscn(3), or NULL to begin iteration. starting fresh? pass NULL. mid-walk? pass the handle you already have.

πŸ’… RETURN VALUE πŸ’…

returns a pointer to the next Elf_Scn structure in the section list. or NULL if there are no more sections, or if elf is NULL. yeah, NULL in, NULL out, the universe is balanced. 🫢


πŸ‘‘ SEE ALSO πŸ‘‘

go read those too, they're the friend group.


⭐ ATTRIBUTES ⭐

no tables here bestie, we're doing this as a list, but the facts are exactly the same:

  • Interface: elf_nextscn()
  • Attribute: Thread safety
  • Value: MT-Safe

so yes, she is thread safe. go off. πŸ”₯


πŸ™ˆ REPORTING BUGS πŸ™ˆ

found a bug? not the vibe, but okay, tell the people:


real talk: NULL from this function doesn't mean something broke, it usually just means you finished walking the section list. don't panic, you ate. πŸ’€

and that's the whole page, no cap. this was Libelf, dated 2025-06-30, and it's ELF_NEXTSCN(3) β€” now go iterate those sections, bestie, you've got this. πŸ’œβœ¨
