- get the base offset for an object file
cc [ flag ... ] file ... -lelf [ library ... ] #include <libelf.h> off_t elf_getbase(Elf *elf);
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.
