Usage

#include <libelf.h>

int

elf_getshdrnum(Elf *elf, size_t *shnum);

Library

library “libelf”

Overview

Function elf_getshdrnum() retrieves the number of ELF sections associated with descriptor elf and stores it into the location pointed to by argument shnum.

This routine allows applications to uniformly process both normal ELF objects, and ELF objects that use extended section numbering.

Return values

Function elf_getshdrnum() returns zero value if successful, or -1 in case of an error.

Errors

Function elf_getshdrnum() can fail with the following errors:

[ELF_E_ARGUMENT]: A NULL value was passed in for argument elf.
[ELF_E_ARGUMENT]: Argument elf was not for an ELF file.
[ELF_E_ARGUMENT]: Argument elf lacks an ELF Executable header.
