ELF Library Functionself32_getshdr(3ELF)


NAME

 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_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 elf32_getshdr 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;

while the elf64_getshdr 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;

For the 64-bit class, replace 32 with 64 as appropriate.

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