Elf32_Phdr *elf32_getphdr(Elf *elf);
Elf64_Phdr *elf64_getphdr(Elf *elf);
```

# [DESCRIPTION](#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.
