       gelf_getehdr() retrieve the ELF header of the binary referenced by elf
       as a class-independent GElf_Ehdr representation.


PARAMETERS
       elf    Pointer to an ELF descriptor.

       dest   Pointer to a caller-provided GElf_Ehdr structure that will
              receive the translated file header. Must not be NULL.  On
