The elf_getbase() function returns the file offset of the first byte of the file or archive member associated with elf, if it is known or obtainable, and −1 otherwise. A null elf is allowed, to simplify error handling; the return value in this case is −1. The base offset of an archive member is the beginning of the member's information, not the beginning of the archive member header.
