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.

SEE ALSO¶
