.TH ELF32_NEWPHDR 3 2024-08-14 "Libelf" "Libelf Programmer's Manual"
.SH NAME
elf32_newphdr, elf64_newphdr \- create a new program header table for a
32-bit or 64-bit ELF object file
.SH SYNOPSIS
.nf
.B #include <libelf.h>
.BI "Elf32_Phdr *elf32_newphdr(Elf *" elf ", size_t " count ");"
.BI "Elf64_Phdr *elf64_newphdr(Elf *" elf ", size_t " count ");"
.SH DESCRIPTION
Create a new program header table for the ELF object file referred to by
.IR elf .
The number of entries in the new program header table is specified by
.IR count .
A
.I count
of zero removes the existing program header table.
The function allocates a new array of
.B Elf32_Phdr
and makes it the program header table for
.IR elf .
The new program header contents are set to zero and any previous program
header table is discarded. An ELF header must exist before creating a
program header table.
.SH PARAMETERS
.TP
.I elf
Pointer to the ELF object for which a new program header table is to be created.
.TP
.I count
The number of entries in the new program header table. A count of zero removes
the existing program header table.
.SH RETURN VALUE
On success, return a pointer to the first
.B Elf32_Phdr
in the newly created program header table. If
.I elf
is NULL then return NULL. If an error occurs, return NULL and set a libelf
error code.
