ELF_GETSHDR(3E)						       ELF_GETSHDR(3E)

NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

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

     #include <libelf.h>

     Elf32_Shdr	*elf32_getshdr(Elf_Scn *scn);
     Elf64_Shdr	*elf32_getshdr(Elf_Scn *scn);

DESCRIPTION    [Toc]    [Back]

     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;

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

     The 64-bit	class works identically, simply	replacing all instances	of 32
     in	the description	and table with 64.
