Function elf32_newehdr
() returns a pointer
to a 32 bit Elf32_Ehdr structure. Function
elf64_newehdr
() returns a pointer to a 64 bit
Elf64_Ehdr structure.
When argument elfclass has value
ELFCLASS32
, function
gelf_newehdr
() returns the value returned by
elf32_newehdr
(elf). When
argument elfclass has value
ELFCLASS64
it returns the value returned by
elf64_newehdr
(elf).
If a fresh header structure is allocated, the members of the structure are initialized as follows:
EI_MAG0
,
EI_MAG1
, EI_MAG2
and
EI_MAG3
are set to the ELF signature.EI_CLASS
is set
to the ELF class associated with the function being called or to argument
elfclass for function
gelf_newehdr
().EI_DATA
is set
to ELFDATANONE
.EI_VERSION
is
set to the ELF library's operating version set by a prior call to
elf_version(3).EM_NONE
.ELF_K_NONE
.Other members of the header are set to zero. The application is
responsible for changing these values as needed before calling
elf_update
().
If successful, these three functions set the
ELF_F_DIRTY
flag on ELF descriptor
elf.
