Description

File format of an ELF header.

Byte order of members depends on e_ident value. This code comes directly from "System V Application Binary Interface, Edition 4.1" and the FreeBSD elf(5) man page, and the "Executable and Linkable Format (ELF) Portable Formats Specifications, Version 1.2" and not from any header file.
