# elf64\_getphdr(3)

retrieve the program header table for a 32-bit or 64-bit ELF object file

Part of [elf32\_getphdr(3)](/elf32_getphdr/3.md).

## NAME

elf32\_getphdr, elf64\_getphdr - retrieve the program header table for a 32-bit or 64-bit ELF object file

## SYNOPSIS

```
#include <libelf.h>
Elf32_Phdr *elf32_getphdr(Elf *elf);
Elf64_Phdr *elf64_getphdr(Elf *elf);
```

## DESCRIPTION

Retrieve the program header table for the given ELF descriptor *elf*. The number of elements in the program header table can be retrieved with **elf32\_getphdrnum** and **elf64\_getphdrnum**. **elf32\_newphdr** and **elf64\_newphdr** change the size of the program header table or to delete it. If changing an element of the program header table, you must call elf\_flagphdr with **ELF\_C\_SET** and **ELF\_F\_DIRTY** in order to write the new data to disk.

## PARAMETERS

- *elf*

  ELF descriptor from which to retrieve the program header table.

## RETURN VALUE

On success, return a pointer to the program header table. Return NULL if there is no program header.  On failure, return NULL and set a libelf error code.
