DESCRIPTION

The return value of elf_next() is suitable for use in a loop invoking elf_begin().

EXAMPLES
To process all the members of an archive use:
Elf_Cmd cmd; Elf *archive, *e; ... cmd = ELF_C_READ; archive = elf_begin(fd, cmd, NULL); while ((e = elf_begin(fd, cmd, archive)) != (Elf *) 0) { ... process `e' here ... cmd = elf_next(e); elf_end(e); } elf_end(archive);
