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.
