       files.


SYNOPSIS
       #include <libelf.h>

       void elf_fill(int fill);


DESCRIPTION
       The elf_fill function sets the fill byte used by libelf to pad new gaps
       between ELF sections or data elements when an ELF object file is
       resized or realigned using elf_update.  The default fill byte used by
       libelf is zero.


PARAMETERS

              This value should be between 0 and 255 (inclusive).  Only the
              least significant 8 bits are used.


RETURN VALUE
