NAME

elf32_getshdr, elf64_getshdr - retrieve class-dependent section header for elf32 and elf64 ﬁles, respec-

tively

SYNOPSIS

cc [ﬂag... ] ﬁle...

-lelf [library ] ...

#include <libelf.h>

Elf32_Shdr *elf32_getshdr(Elf_Scn *scn);

Elf64_Shdr *elf64_getshdr(Elf_Scn *scn);

DESCRIPTION

For a 32-bit class ﬁle,

elf32_getshdr returns a pointer to a section header for the section descriptor

scn. Otherwise, the ﬁle is not a 32-bit class ﬁle, scn was null, or an error occurred;

elf32_getshdr

then returns NULL. The header includes the following members.

Elf32_Word sh_name;

Elf32_Word sh_type;

Elf32_Word sh_flags;

Elf32_Addr sh_addr;

Elf32_Off sh_offset;

Elf32_Word sh_size;

Elf32_Word sh_link;

Elf32_Word sh_info;

Elf32_Word sh_addralign;

Elf32_Word sh_entsize;

For a 64-bit class ﬁle, elf64_getshdr

returns a pointer to a section header for the section descriptor

scn. Otherwise, the ﬁle is not a 64-bit class ﬁle, scn was null, or an error occurred;

elf64_getshdr

then returns NULL. The header includes the following members.

Elf64_Word sh_name;

Elf64_Word sh_type;

Elf64_Xword sh_flags;

Elf64_Addr sh_addr;

Elf64_Off sh_offset;

Elf64_Xword sh_size;

Elf64_Word sh_link;

Elf64_Word sh_info;

Elf64_Xword sh_addralign;

Elf64_Xword sh_entsize;

If the program is building a new ﬁle, it is responsible for creating the ﬁle’s ELF header before creating

sections.
