Update.
2003-11-07 Jakub Jelinek <jakub@redhat.com>
* io/ftw.c (NFTW_OLD_NAME, NFTW_NEW_NAME): Define.
(ftw_dir, ftw_startup): Add __attribute ((noinline)).
(NFTW_OLD_NAME, NFTW_NEW_NAME): New functions.
(NFTW_NAME): Only define if !_LIBC, add versioned_symbol
and compat_symbol.
* io/ftw64.c (NFTW_OLD_NAME, NFTW_NEW_NAME): Define.
* io/Versions (libc): Export nftw@@GLIBC_2.3.3
and nftw64@@GLIBC_2.3.3.
* io/ftw.h (FTW_ACTIONRETVAL): New flag.
(FTW_CONTINUE, FTW_STOP, FTW_SKIP_SUBTREE, FTW_SKIP_SIBLINGS): New.
* io/ftw.c (ftw_dir): Add old_dir argument.
Clear result if it was FTW_SKIP_SIBLINGS after processing all
dir entries. Change cwd back if old_dir != NULL.
(process_entry): Adjust caller. Don't change cwd back here.
Change FTW_SKIP_SUBTREE result to 0.
(ftw_startup): Adjust ftw_dir caller.
Clear result if it was FTW_SKIP_SUBTREE or FTW_SKIP_SIBLINGS.
* io/ftwtest.c (skip_subtree, skip_siblings): New variables.
(options, main): Add --skip-subtree and --skip-siblings options.
(cb): Use return FTW_CONTINUE instead of return 0.
Handle --skip-subtree and --skip-siblings.
* io/ftwtest-sh: Add tests for FTW_ACTIONRETVAL.
* manual/filesys.texi: Document FTW_ACTIONRETVAL.
