elf32_getehdr

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  allo-
       cate a new header if one exists already. If no header exists for elf32_getehdr(), 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 functions 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
       information differs between standard ELF files to those that require Extended Sections.
