elf_getshdr(S)


elf_getshdr: elf32_getshdr -- retrieve class-dependent section header

Syntax

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

#include <libelf.h>

Elf32_Shdr *elf32_getshdr(Elf_Scn *scn);

Description

For a 32-bit class file, elf_getshdr(S) returns a pointer to a section header for the section descriptor scn.

If elf_getshdr( ) returns NULL, the file is not a 32-bit class file, scn was null, or an error occurred.

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;

If the program is building a new file, it must create the file's ELF header before creating sections.

Diagnostics

Error conditions are identified through the routine elf_error(S).
