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
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 descriptorelf. If no header exists for the descriptor, elf32_newehdr()
allocates a clean one, but it otherwise behaves the same aself32_getehdr(). It does not allocate 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;

ELF Library Functions elf32_getehdr(3ELF)
The elf32_newehdr() function automatically sets the
ELF_F_DIRTY bit. See elf_flagdata(3ELF).
An application can use elf_getident() to inspect the iden-
tification 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.ATTRIBUTES
