elf_getscn(3)

Usage

#include <libelf.h>

Elf_Scn *elf_getscn(Elf *elf, size_t index);

Overview

The elf_getscn function retrieves a section descriptor for the section at the specified index in the ELF object referred to by elf.

Parameters

elf: An Elf pointer to the ELF object from which the section descriptor is to be retrieved.

index: A size_t value representing the index of the section whose descriptor is to be retrieved. Section indices start at 0. The section at index 0 is always SHT_NULL and does not contain any data.

Return value

The elf_getscn function returns a pointer to the Elf_Scn for the section at the specified index. If an error occurs, it returns NULL and sets an appropriate libelf error code.
