39 .Fn elf_rand "Elf *archive" "off_t offset"
43 function causes the ELF descriptor
45 to be adjusted so that the next call to
47 will provide access to the archive member at byte offset
52 is the byte offset from the start of the archive to the beginning of
53 the archive header for the desired member.
55 Archive member offsets may be retrieved using the
63 if successful or zero in case of an error.
65 To process all the members of an archive use:
66 .Bd -literal -offset indent
71 archive = elf_begin(fd, cmd, NULL);
72 while ((e = elf_begin(fd, cmd, archive)) != (Elf *) 0)
74 ... process `e' here ...
77 off = ...new value...;
78 if (elf_rand(archive, off) != off) {
85 To rewind an archive, use:
86 .Bd -literal -offset indent
89 if (elf_rand(archive, SARMAG) != SARMAG) {
96 may fail with the following errors:
