NAME
     elf_getident -- return the initial bytes of a file

LIBRARY
     ELF Access Library (libelf, -lelf)

SYNOPSIS
     #include <libelf.h>

     char *
     elf_getident(Elf *elf, size_t *sz);

DESCRIPTION
     Function elf_getident() returns a pointer to the initial bytes of the file for descriptor elf.

     If argument sz is non-null, the size of the identification area returned is written to the location pointed to by sz.  This location is set
     to zero on errors.

RETURN VALUES
     Function elf_getident() will return a non-NULL pointer to the initial bytes of the file if successful, or NULL if an error condition is
     detected.

ERRORS
     Function elf_getident() can fail with the following errors:

     [ELF_E_ARGUMENT]  A NULL value was passed in for argument elf.

     [ELF_E_SEQUENCE]  ELF descriptor elf was opened for writing and function elf_getident() was called before a call to elf_update(3).
