elf32_getehdr(3ELF)	     ELF Library Functions	   elf32_getehdr(3ELF)

NAME
       elf32_getehdr,  elf32_newehdr,  elf64_getehdr, elf64_newehdr - retrieve
       class-dependent object file header

SYNOPSIS
       cc [ flag ... ] file ... -lelf [ library ... ]
       #include <libelf.h>

       Elf32_Ehdr *elf32_getehdr(Elf *elf);

       Elf32_Ehdr *elf32_newehdr(Elf *elf);

       Elf64_Ehdr *elf64_getehdr(Elf *elf);

       Elf64_Ehdr *elf64_newehdr(Elf *elf);

DESCRIPTION
       For a 32-bit class file, elf32_getehdr() returns a pointer  to  an  ELF
       header,	if  one	 is available for the ELF descriptor elf. If no header
       exists for the descriptor, elf32_newehdr() allocates a clean  one,  but
       it  otherwise behaves the same as elf32_getehdr(). It does not allocate
       a new header if one exists already. If no header exists for elf32_gete‐
       hdr(),  one  cannot  be	created	 for  elf32_newehdr(),	a system error
       occurs, the file is not a 32-bit class file, or elf is NULL, both func‐
       tions return a null pointer.

       For the 64−bit class, replace 32 with 64 as appropriate.

       The header includes the following members:

       unsigned char  e_ident[EI_NIDENT];
       Elf32_Half     e_type;
       Elf32_Half     e_machine;
       Elf32_Word     e_version;
       Elf32_Addr     e_entry;
       Elf32_Off      e_phoff;
       Elf32_Off      e_shoff;
       Elf32_Word     e_flags;
       Elf32_Half     e_ehsize;
       Elf32_Half     e_phentsize;
       Elf32_Half     e_phnum;
       Elf32_Half     e_shentsize;
       Elf32_Half     e_shnum;
       Elf32_Half     e_shstrndx;

       The  elf32_newehdr()  function  automatically sets the ELF_F_DIRTY bit.
       See elf_flagdata(3ELF).

       An application can use elf_getident()  to  inspect  the	identification
       bytes from a file.

       An  application	can use elf_getshnum() and elf_getshstrndx() to obtain
       section header information. The location of this section header	infor‐
       mation  differs	between	 standard  ELF	files  to  those  that require
       Extended Sections.
