✨ GELF_GETEHDR ✨

okay bestie, welcome to the Libelf Programmer's Manual πŸ’– this one's called gelf_getehdr, and it's about grabbing the header of an ELF binary as a class-independent structure. yes, we're doing elf lore today. slay 🧚


🌸 NAME 🌸

gelf_getehdr β€” retrieve the header of an ELF binary as a class-independent structure πŸ¦‹


πŸ’… SYNOPSIS πŸ’…

#include <gelf.h>

GElf_Ehdr *gelf_getehdr(Elf *elf, GElf_Ehdr *dest );

✨ DESCRIPTION ✨

so like, gelf_getehdr() goes and retrieves the ELF header of the binary that elf is pointing at, and it hands it to you as a class-independent GElf_Ehdr representation. it's giving "I don't care what class you are, I'll translate it for you" energy πŸ‘‘


πŸŽ€ PARAMETERS πŸŽ€

  • elf β€” a pointer to an ELF descriptor. your little handle on the binary 🫢
  • dest β€” a pointer to a caller-provided GElf_Ehdr structure that's gonna receive the translated file header. it must not be NULL, bestie, fr fr. on success, the function stores the header in *dest πŸ’–

🌈 RETURN VALUE 🌈

  • on success: returns dest. iconic. ✨
  • on failure: returns NULL and sets elf_errno. πŸ’€
  • if elf is NULL: NULL is returned and elf_errno is not set. not even a little. no cap πŸ™ˆ

πŸ‘‘ SEE ALSO πŸ‘‘


πŸ“ ATTRIBUTES πŸ“

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

so yeah, she's thread safe. main character behavior πŸ’…


😭 REPORTING BUGS 😭

found a bug? don't suffer in silence, tell the girlies:


that's the whole vibe, bestie. go forth and read some ELF headers. πŸ’œ
