elf32_newphdr
GELF_NEWPHDR(3) BSD Library Functions Manual GELF_NEWPHDR(3)
NAME
elf32_newphdr, elf64_newphdr, gelf_newphdr -- allocate an ELF program header table
LIBRARY
ELF Access Library (libelf, -lelf)
SYNOPSIS
#include <libelf.h>
Elf32_Phdr *
elf32_newphdr(Elf *elf, size_t count);
Elf64_Phdr *
elf64_newphdr(Elf *elf, size_t count);
#include <gelf.h>
void *
gelf_newphdr(Elf *elf, size_t count);
DESCRIPTION
These functions allocate an ELF Program Header table for an ELF descriptor. Elf32_Phdr and Elf64_Phdr descriptors are described further in
elf(5).
Functions elf32_newphdr() and elf64_newphdr() allocate a table of count Elf32_Phdr and Elf64_Phdr descriptors respectively, discarding any
existing program header table already present in the ELF descriptor elf. A value of zero for argument count may be used to delete an exist-
ing program header table from an ELF descriptor.
Function gelf_newphdr() will return a table of Elf32_Phdr or Elf64_Phdr with count elements depending on the ELF class of ELF descriptor elf.
The functions set the ELF_F_DIRTY flag on the program header table. All members of the returned array of Phdr structures will be initialized
to zero.
After a successful call to these functions, the pointer returned by a prior call to elf32_getphdr() or elf64_getphdr() on the same descriptor
elf will no longer be valid.
RETURN VALUES
The functions a valid pointer if successful, or NULL in case an error was encountered.
ERRORS
These functions may fail with the following errors:
[ELF_E_ARGUMENT] Argument elf was NULL.
[ELF_E_ARGUMENT] Argument elf was not a descriptor for an ELF object.
[ELF_E_CLASS] ELF descriptor elf was of an unrecognized class.
[ELF_E_RESOURCE] An out of memory condition was detected.
[ELF_E_SEQUENCE] An executable header was not allocated for ELF descriptor elf before using these APIs.
