ELF_GETDATA(3)

💖 ELF_GETDATA 💖

okay bestie, welcome to elf_getdata from the Libelf Programmer's Manual — she's a libelf function and she's here to hand you the data, no cap ✨

✨ NAME ✨

elf_getdata — get the washed data of a section 🧼🦋

🌸 SYNOPSIS 🌸

#include <libelf.h>

Elf_Data * elf_getdata (Elf_Scn *scn, Elf_Data *data);

💅 DESCRIPTION 💅

so the elf_getdata() function is literally your girl for retrieving the data buffers of the section scn. 🎀

ngl there can be more than one buffer in there — but only if the user explicitly added them. when a file gets read, libelf keeps it simple and creates exactly one data buffer. one. single. icon. 👑

• wanna get the first buffer in the list? just pass a null pointer in the parameter data. periodt.
• wanna get the next data buffer? pass the value that was previously returned in the data parameter. iykyk 🔁
• and if there are no more buffers left in the list? you get a null pointer back. bye bestie 👋

⚠️ okay important: if data is not a null pointer, it must be a descriptor for a buffer associated with the section scn. if it's not, you get a null pointer returned. no cap.

and to make error handling easier for you (so thoughtful fr fr), elf_getdata also returns a null pointer if the scn parameter is a null pointer. 🫶

🎀 SIGN-OFF 🎀
