elf_getshdr(3E)

NAME
     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 *elf32_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;

     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.
