NAME
       elf_getbase - Retrieve the base offset for an ELF object file.


SYNOPSIS
       #include <libelf.h>

       int64_t elf_getbase(Elf *elf);


DESCRIPTION
       elf_getbase returns the file offset of the first byte of the ELF
       descriptor elf.  If elf is a member of an archive and has ELF kind
       ELF_K_AR, the base offset is the offset of the ELF object within the
       archive.  For other ELF object types the base offset is 0.


PARAMETERS
       elf    The ELF descriptor.


RETURN VALUE
       Return the base offset of elf if its ELF kind is ELF_K_AR, otherwise
       return 0.  If elf is NULL, return -1.
