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.
