NAME

       elf32_newehdr, elf64_newehdr - create a new ELF header for a 32-bit or 64-bit ELF object file

SYNOPSIS

       #include <libelf.h>

       Elf32_Ehdr *elf32_newehdr(Elf *elf);
       Elf64_Ehdr *elf64_newehdr(Elf *elf);

DESCRIPTION

       This  function initializes a new ELF header and associates it with elf.  If elf already has an ELF header
       associated with it, no new header will be created and the existing  header  will  be  returned.   An  ELF
       header must be present before calling elf_newscn or elf_newphdr.

PARAMETERS

       elf    ELF descriptor for which a new ELF header is to be created.

RETURN VALUE

       On  success,  return  a  pointer  to  the  newly  created  ELF  header.  If elf already has an ELF header
       associated with it, this pre-existing header is returned and no new header is created. On failure, return
       NULL and set a libelf error code.
