Juergen,
This is great! If you can figure out how to get this
right, I would really appreciate it. If you have a
tape drive handy, definitely test with that. My first
attempts here actually broke reading from tape drives,
which is why the current code is so conservative.
Minor style comments:
else if (S_ISCHR(st.st_mode) &&
!ioctl(fd, DIOCGMEDIASIZE, &mediasize) && mediasize) {
Please be explicit: S_ISCHR() && ioctl() == 0 && mediasize > 0
archive_read_extract_set_skip_file(a, st.st_dev, st.st_ino);
extract_skip_file isn't needed here; we don't read the
contents of device nodes.
Let me know as soon as you have something you're confident of.
Cheers,
Tim
