elf_getshdr(ELF)


elf_getshdr: elf32_getshdr, elf64_getshdr -- retrieve class-dependent section header

Synopsis

   cc [flag . . . ] file . . . -lelf [library] . . .
   

#include <libelf.h>

Elf32_Shdr *elf32_getshdr(Elf_Scn *scn);

Elf64_Shdr *elf64_getshdr(Elf *elf);

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;

elf64_getshdr provides the same functionality for 64-bit class files. The header includes the following members:


Elf64_Word sh_name; Elf64_Word sh_type; Elf64_Word 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.
