NAME
       gelf_getclass - return the ELF class (32-bit or 64-bit) for an object

SYNOPSIS
       #include <gelf.h>

       int gelf_getclass(Elf *elf);


DESCRIPTION
       gelf_getclass() returns the class of the ELF object referenced by elf.
       The class of a valid ELF file will be one of:

       ELFCLASS32
              The object is a 32-bit ELF class.

       ELFCLASS64
              The object is a 64-bit ELF class.

       If elf does not denote a valid ELF object, or the class cannot be
       determined, ELFCLASSNONE is returned.


RETURN VALUE
       Returns ELFCLASS32 or ELFCLASS64 on success.  If elf is NULL or does
       not refer to a valid ELF binary with kind ELF_K_ELF, then ELFCLASSNONE
       is returned.
