elf32_getphdr(3ELF) ELF Library Functions elf32_getphdr(3ELF)
NAME
elf32_getphdr, elf32_newphdr, elf64_getphdr, elf64_newphdr - retrieve
class-dependent program header table
SYNOPSIS
cc [ flag ... ] file... -lelf [ library ... ]
#include <libelf.h>
Elf32_Phdr *elf32_getphdr(Elf *elf);
Elf32_Phdr *elf32_newphdr(Elf *elf, size_t count);
Elf64_Phdr *elf64_getphdr(Elf *elf);
Elf64_Phdr *elf64_newphdr(Elf *elf, size_t count);
DESCRIPTION
For a 32-bit class file, elf32_getphdr() returns a pointer to the pro‐
gram execution header table, if one is available for the ELF descriptor
elf.
elf32_newphdr() allocates a new table with count entries, regardless of
whether one existed previously, and sets the ELF_F_DIRTY bit for the
table. See elf_flagdata(3ELF). Specifying a zero count deletes an
existing table. Note this behavior differs from that of elf32_newehdr()
allowing a program to replace or delete the program header table,
changing its size if necessary. See elf32_getehdr(3ELF).
If no program header table exists, the file is not a 32-bit class file,
an error occurs, or elf is NULL, both functions return a null pointer.
Additionally, elf32_newphdr() returns a null pointer if count is 0.
The table is an array of Elf32_Phdr structures, each of which includes
the following members:
Elf32_Word p_type;
Elf32_Off p_offset;
Elf32_Addr p_vaddr;
Elf32_Addr p_paddr;
Elf32_Word p_filesz;
Elf32_Word p_memsz;
Elf32_Word p_flags;
Elf32_Word p_align;
The Elf64_Phdr structures include the following members:
Elf64_Word p_type;
Elf64_Word p_flags;
Elf64_Off p_offset;
Elf64_Addr p_vaddr;
Elf64_Addr p_paddr;
Elf64_Xword p_filesz;
Elf64_Xword p_memsz;
Elf64_Xword p_align;
For the 64−bit class, replace 32 with 64 as appropriate.
The ELF header's e_phnum member tells how many entries the program
header table has. See elf32_getehdr(3ELF). A program may inspect this
value to determine the size of an existing table; elf32_newphdr() auto‐
matically sets the member's value to count. If the program is building
a new file, it is responsible for creating the file's ELF header before
creating the program header table.
