elf_open()
  and elf_openmemory() are extensions to the
  elf(3) API, for the internal use of
  the Elftoolchain project. Portable applications should not use these
  functions.
The function elf_open() returns an Elf
    descriptor opened with mode ELF_C_READ for the ELF
    object or ar(1) archive referenced
    by the file descriptor in argument fd.
The function elf_openmemory() returns an
    ELF descriptor opened with mode ELF_C_READ for the
    ELF object or ar(1) archive
    contained in the memory area pointed to by the argument
    image. The argument sz specifies
    the size of the memory area in bytes.
NULL if an error occurred.
The behavior of these functions differs from their counterparts
    elf_begin(3) and
    elf_memory(3) in that
    these functions will successfully open malformed ELF objects and
    ar(1) archives, returning an Elf
    descriptor of type ELF_K_NONE.
